Zig 0.7.1 to zig 0.9-dev moved from clang-11 to clang-12, so, from the
|
|
|
|
|
|
surface, I would attribute behavior changes to this. Did you narrow
|
|
|
|
|
|
this down to something specific?

Have you noticed regressions with `zig cc` when upgrading zig? Since
|
|
|
|
|
|
it is covered by "bug stability program[1]", I expect zig upstream to
|
|
|
|
|
|
be quite responsive with regressions there. If C++ behavior changes,
|
|
|
|
|
|
it's probably a fault of a new clang, which should be reported to
|
|
|
|
|
|
Apple (likely with help of zig developers, since they have done this
|
|
|
|
|
|
many times).

We already have //test:hello[2]. Feel free to add yours.

|

|
|
|

|
|
|
|
|
|
I am looking for multi-arch build support in sr.ht, which is "not yet
|
|
|
|
|
|
available"[3], which would be ideal.
|
|
|
|
|
|
|
|
|
|
|
|
Currently I am cross-compiling to a few architectures and checking
|
|
|
|
|
|
whether the resulting "file" command returns an expected string. I
|
|
|
|
|
|
agree qemu-system-<arch> is a good next step. What are your
|
|
|
|
|
|
architectures of interest?

Looking forward to anything that will simplify it's setup/boilerplate.

Interesting!
|
|
|
|
|
|
|
|
|
|
|
|
I have slightly updated the toolchain today:
|
|
|
|
|
|
- added support for darwin-arm64 and linux-arm64 host (though don't
|
|
|
|
|
|
have an arm64 machine to test this with).
|
|
|
|
|
|
- tried to upgrade zig itself, but cross-compilation to darwin-amd64
|
|
|
|
|
|
fails with it; there seems to be a regression somewhere. I will look
|
|
|
|
|
|
into it sometime soon.
|
|
|
|
|
|
|
|
|
|
|
|
... so please rebase before sending patches.

Hi all,
|
|
|
|
|
|
|
|
|
|
|
|
the way plans are panning out now, at some point in 2022H1 bazel-zig-cc
|
|
|
|
|
|
will be scrutinized by much more competent colleagues than myself,
|
|
|
|
|
|
before being moved to github.com/uber (or equivalent). After that major
|
|
|
|
|
|
changes will be much harder to make.
|
|
|
|
|
|
|
|
|
|
|
|
Steeve, if you are still considering on major changes in bazel-zig-cc,
|
|
|
|
|
|
this year is better than next year.
|
|
|
|
|

Applied[1], thank you. Although I left only the acknowledgement in the
|
|
|
|
|
|
README; see [2] for why.

Hi Thomas!

|
|
|

See [1]; I also recommend you to subscribe. I haven't heard of anyone
|
|
|
|
|
|
using bazel-zig-cc, so I guess I'll need to be more careful/upfront
|
|
|
|
|
|
about breaking changes.

Have you found a need/way to specify a different default url for the zig
|
|
|
|
|
|
bundle? I've been playing with it[2], but unsatisfied with the API so
|
|
|
|
|
|
far.

Hi bazel-zig-cc users,
|
|
|
|
|
|
|
|
|
|
|
|
Due to a recent bug-fixing spree in zig, bazel-zig-cc improved quite a
|
|
|
|
|
|
bit:
|
|
|
|
|
|
|
|
|
|
|
|
- `zig c++` no longer errs with the dreaded FileNotFound[1]. This was
|
|
|
|
|
|
very prominent on many-core machines, and now unblocked larger-scale
|
|
|
|
|
|
tests.
|
|
|
|
|
|
- can compile Darwin again: x86_64[2] and aarch64[3]. Although if you
|
|
|
|
|
|
are interested in compiling for Darwin, Jakub's comments in [3] are
|
|
|
|
|
|
must-read.
|
|
|
|
|
|
|
|
|
|
|
|
My only short-term wish-list from Zig today is [4]: if Foundation
|
|
|
|

framework is requested, but zig doesn't find it, the compiler should
|
|
|
|
|
|
fail. Currently only a warning is emitted, and the binary is wedged with
|
|
|
|
|
|
a possibly "difficult to track runtime exception"[5]:
|
|
|
|
|
|
|
|

I added an Upcoming Wishlist category to the README[6], which is:
|
|
|
|
|
|
|
|
|
|
|
|
- Move Zig cache path to bazel root, so bazel clean --expunge clears the
|
|
|
|
|
|
zig cache.
|
|
|
|
|
|
- Provide a way to specify alternative URLs for the zig toolchain
|
|
|
|
|
|
(currently zig is downloaded from jakstys.lt, which is nuts).
|
|
|
|
|
|
- Rename @zig_sdk//:<toolchain>_toolchain to
|
|
|
|
|
|
@zig_sdk//toolchain:<toolchain> or similar; so the user-facing targets
|
|
|
|
|
|
are in their own namespace.
|
|
|
|
|
|
- Provide a way to specify sysroot for Darwin (OSX). See [#Compiling OS X
|
|
|
|
|
|
executables] for an ongoing discussion.
|
|
|
|
|
|
|
|
|
|
|
|
As bazel-zig-cc is only ~10% of my $dayjob, I am not planning to work on
|
|
|
|
|
|
the above any time soon. But it gives a nice starting point for a
|
|
|
|
|
|
question "how do I help/contribute"?
|
|
|
|
|
|
|
|
|
|
|
|
Zig 0.9.0 is 10 days away, I will cut bazel-zig-cc 0.4.0 once that
|
|
|
|
|
|
happens.

Hi folks,
|
|
|
|
|
|
|
|
|
|
|
|
I released v0.4.0-rc1; notable changes from v0.3.4:
|
|
|
|
|
|
|
|
|
|
|
|
- upgrade to zig 0.9.0-dev.1950+a76910b69. Now compilation on Darwin
|
|
|
|
|
|
will fail if `-framework` was specified, but wasn't able to be
|
|
|
|
|
|
linked[1]. This happens on darwin/arm64, which I had to disable CI
|
|
|
|
|
|
for. A patch that passes `zig cc --sysroot=/path/to/sdk` is sought
|
|
|
|
|
|
for, if you care about darwin/arm64 (or darwin in general).
|
|
|
|
|
|
- remove default `-O3`[2]. This now re-enables UBSAN by default, which
|
|
|
|
|
|
is an important default in upstream[3].
|
|
|
|
|
|
|
|
|
|
|
|
v0.4.0 will be released when zig 0.9.0 is released, which is scheduled
|
|
|
|
|
|
for Dec 20.
|
|
|
|
|
|
|
|
|
|
|
|
About undefined behavior (removal of `-O3`)
|
|
|
|
|
|
-------------------------------------------
|
|
|
|
|
|
|
|
|
|
|
|
The second change broke my use of brotli, which relies on undefined
|
|
|
|
|
|
behaior[4]. This is my ugly way to mitigate it:

Hi folks,
|
|
|
|
|
|
|
|
|
|
|
|
I released v0.4.0-rc2, this time only upgrading zig to
|
|
|
|
|
|
0.9.0-dev.1968+ff93486d0 (from 1950). Two notable changes with regards
|
|
|
|
|
|
to `zig cc`:
|
|
|
|
|
|
|
|
|
|
|
|
- [darwin] zig cc will now fail hard if `-framework` is specified, but
|
|
|
|
|
|
not found. It used to produce a strange-looking, likely-unworkable
|
|
|
|
|
|
binary.
|
|
|
|
|
|
- glibc stubs are fixed[2]. I have been waiting for this for a long
|
|
|
|
|
|
time. More on this in HN[3].
|
|
|
|
|
|
|
|
|
|
|
|
These resolve the last known high-severity issues. Thanks zig team! As I
|
|
|
|
|
|
am not expecting any final-day fixes in zig itself, there likely won't
|
|
|
|
|
|
be an rc3. A few weeks after 0.9.0 is released, I am planning to remove
|
|
|
|
|
|
the dev versions from my mirror[4].
|
|

Tip of the day
|
|
|
|
|
|
--------------
|
|
|
|
|
|
|
|
|
|
|
|
This is helpful in `.bazelrc`:
|
|
|
|
|
|
|
|
|
|
|
|
build --compilation_mode=opt
|
|
|
|
|
|
|
|
|
|
|
|
This makes non-tests to be compiled with -O2. Tests will be compiled
|
|
|
|
|
|
without optimizations, making compilation faster, and retaining
|
|
|
|
|
|
UBSAN[5].

Open questions
|
|
|
|
|
|
--------------
|
|
|
|
|
|
|
|
|
|
|
|
The question from last week[6] still holds: how to adjust CFLAGS for an
|
|
|
|
|
|
external Bazel project?

Hi folks,
|
|
|
|
|
|
|
|
|
|
|
|
I cannot yet release bazel-zig-cc 0.4.0, because there is a regression
|
|
|
|
|
|
in `zig c++`; you may follow along here[1].
|
|
|
|
|
|
|
|
|
|
|
|
I am happy bazel-zig-cc CI caught this[2]; this regression was quite
|
|
|
|
|
|
easy to trigger.
|
|
|
|
|
|
|
|
|
|
|
|
I accidentally pushed 0.4.0 a few days ago, but promptly deleted the
|
|
|
|
|
|
tag. If you managed to catch 0.4.0 (it was there for <1 hour), please
|
|
|
|
|
|
remove the tag. My mistake, I will try harder not to do this again.
|
|
|
|
|
|
|
|
|
|
|
|
Note that this affects only glibc targets; I am successfully using zig
|
|
|
|
|
|
0.9.0 with a musl target (0.4.0-rc2 with a custom zig version).
|
|
|
|
|
|
|
|
|
|

Hello,
|
|
|
|
|
|
|
|
|
|
|
|
I'm a big fan of this project. It's *lot* easier than trying to figure
|
|
|
|
|
|
out other Bazel CC toolchains.
|
|
|
|
|
|
|
|
|
|
|
|
One of my teammates ran into a curious error on an M1 Macbook using
|
|
|
|
|
|
the latest bazel-zig-cc.
|
|
|
|
|
|
|
|
|
|
|
|
cc/toolchain/defs.bzl", line 219, column 70, in _zig_repository_impl
|
|
|
|
|
|
zig_include_root =
|
|
|
|
|
|
repository_ctx.attr.host_platform_include_root[host_platform]
|
|
|
|
|
|
Error: key "macos-arm64" not found in dictionary
|
|
|
|
|
|
|
|
|
|
|
|
I traced this to toolchain/defs.bzl [1] which uses `uname -m` to get
|
|
|
|
|
|
the architecture. It looks like bazel-zig-cc only supports aarch64 but
|
|
|
|
|
|
M1 Macs return arm64.
|
|
|
|
|
|
|
|
|
|
|
|
What's really spooky is that bazel-zig-cc worked on my M1 mac but it
|
|
|
|
|
|
didn't work for two other devs on my team also on M1 macs; they got
|
|
|
|
|
|
the above error.
|
|
|
|
|
|
|
|
|
|
|
|
I was able to work around the problem with the following steps:
|
|
|
|
|
|
https://gist.github.com/jschaf/c9be10d806020087680310e49f6e2072.
|
|
|
|
|
|
|
|
|
|
|
|
- Uploaded all zig SDKs to my own hosting. I had to use my own hosting
|
|
|
|
|
|
to create macos-arm64 which is really just a copy of maco-aarch64 but
|
|
|
|
|
|
I had to change the folder name to match the archive name.
|
|
|
|
|
|
|
|
|
|
|
|
- Added "macos-arm64" to host_platform_include_root, similar to "macos-aarch64".
|
|
|
|
|
|
|
|
|
|
|
|
I'm by no means a Bazel toolchain expert, but I would have thought
|
|
|
|
|
|
there's a better way to get the host platform architecture than by
|
|
|
|
|
|
shelling out to uname. Appears that there's not [2] but that answer is
|
|
|
|
|
|
from 2017. Maybe platforms provide a way out [3]?

Hi, Joe,
|
|
|
|
|
|
|
|
|
|
|
|
that's interesting indeed. I don't have an M1 mac, nor know anyone
|
|
|
|
|
|
with M1 mac, to test this "more closely".

|

|
|
|
|
|
|
|
|

Re [3]: looks like `declare_toolchains` is an external function, and it
|
|
|
|
|
|
accepts `host` as a parameter, which should be set by the caller? If so,
|
|
|
|
|
|
I am not following how that would help.
|
|
|
|
|
|
|
|
|
|
|
|
If you can dig in for more information why `uname -m` returns arm64 vs
|
|
|
|
|
|
aarch64 (OSX minor version? something else?). If there is no other way
|
|
|
|
|
|
out, I would be OK to for an internal workaround to map darwin/arm64 to
|
|
|
|
|
|
darwin/aarch64 during download, provided it's the only problem
|
|
|
|
|
|
|
|
|
|
|
|
Is downloading the toolchain the only problem? Once you add that
|
|
|
|
|
|
workaround, does it keep working as one would expect?

|
|

I think I figured it out. It depends on whether the Bazel binary is an amd6=
|
|
|
|
|
|
4
|
|
|
|
|
|
or arm64 binary. I installed the amd64 version Bazel first on my team befor=
|
|
|
|
|
|
e
|
|
|
|
|
|
arm64 was available. macOS runs the amd64 binary and propagates the
|
|
|
|
|
|
architecture down the call chain, including the subshell to uname. I can
|
|
|
|
|
|
confirm by running uname under x86_64 emulation with:
|
|
|
|
|
|
|
|
|
|
|
|
arch -x86_64 uname -m
|
|
|
|
|
|
x86_64
|
|
|
|
|
|
|
|
|
|
|
|
So I think this package will not work for an M1 mac running an arm64 versio=
|
|
|
|
|
|
n
|
|
|
|
|
|
of Bazel. I think an internal translation from arm64 to aarch64 is likely t=
|
|
|
|
|
|
he
|
|
|
|
|
|
easiest approach.

Yep, as long as both the host_platform_sha256 and
|
|
|
|
|
|
host_platform_include_root dictionaries account for arm64.

Hi Joe, thanks for clarifying!
|
|
|
|
|
|
|
|
|
|
|
|
In that case, I will accept a patch that rewrites the architecture for
|
|
|
|
|
|
OSX from arm64 to aarch64. Please don't extend the dict though, as it
|
|
|
|
|
|
will be duplicate information and thus harder to maintain. Something
|
|
|
|
|
|
along the lines:
|
|
|
|
|
|
|
|
|
|
|
|
arch = `uname -m`
|
|
|
|
|
|
# two sentence explanation (an extract from your email would suffice)
|
|
|
|
|
|
if macos and arch == "arm64"
|
|
|
|
|
|
arch = "aarch64"
|
|
|
|
|
|
|
|
|
|
|
|
... keep going with the `arch` variable.
|
|
|
|
|
|
|
|
|
|
|
|
See https://sr.ht/~motiejus/bazel-zig-cc/#questions-amp-contributions
|
|
|
|
|
|
for how to send the patch. Thanks for your report!

Hi all,
|
|
|
|
|
|
|
|
|
|
|
|
I just released bazel-zig-cc v0.4.0. It is the first release after zig
|
|
|
|
|
|
0.9.0 came out. I didn't cut a release with 0.9.0 due to[1]. Many thanks
|
|
|
|
|
|
Xavier for addressing that one!
|
|
|
|
|
|
|
|
|
|
|
|
This version has no known upstream issues, and, as usual, a few ones[2]
|
|
|
|
|
|
I will be accepting patches to, or will get to myself at some point.
|
|
|
|
|
|
|
|
|
|
|
|
Happy hacking,
|

Hi all,
|
|
|
|
|
|
|
|
|
|
|
|
I cut bazel-zig-cc v0.4.1, which upgrades zig to
|
|
|
|
|
|
0.10.0-dev.399+366c76744. Notably, it implements the following linker
|
|
|
|
|
|
args:
|
|
|
|
|
|
|
|
|
|
|
|
* --whole-archive, -whole-archive
|
|
|
|
|
|
* --no-whole-archive, -no-whole-archive
|
|
|
|
|
|
* -s, --strip-all
|
|
|
|
|
|
* -S, --strip-debug
|
|
|
|
|
|
|
|
|
|
|
|
... which were surfaced by Envoy trying out bazel-zig-cc[1].
|
|
|
|
|
|
|
|
|
|
|
|
I also renewed my gpg key (just updated the expiry date, keys are
|
|
|
|
|
|
unchanged), which you can find in today [2]. For some inexplicable
|
|
|
|
|
|
reason I keep signing my releases.
|
|
|
|
|
|
|
|
|
|
|

Hi all,
|
|
|
|
|
|
|
|
|
|
|
|
I cut bazel-zig-cc v0.4.2, which upgrades zig to
|
|
|
|
|
|
0.10.0-dev.430+35423b005. Notable changes:
|
|
|
|
|
|
- fix linux kernel's aarch64 include paths, use stable kernel for
|
|
|
|
|
|
headers[1].
|
|
|
|
|
|
- implement --hash-style linker parameter[2].
|
|
|
|
|
|
|
|
|
|
|
|
I am working on aarch64 at my dayjob, which resulted in (1). The latter
|
|
|
|
|
|
was surfaced in envoy's ongoing investigation into zig-cc and
|
|
|
|
|
|
bazel-zig-cc[3].

Hi all,
|
|
|
|
|
|
|
|
|
|
|
|
I released v0.4.3. It only zig, which fixes[1] `--hash-style` and
|
|
|
|
|
|
`--whole-archive`. The README was also updated following some users'
|
|
|
|
|
|
questions[2]. "The starlark" remains the same.
|
|
|
|
|
|
|
|
|
|
|
|
At some point I will not be releasing new versions of bazel-zig-cc when
|
|
|
|
|
|
*only* zig is updated; at that point, you will need to download zig
|
|
|
|
|
|
provide it to bazel-zig-cc. Something akin to [3].
|
|

Hi folks,
|
|
|
|
|
|
|
|
|
|
|
|
I spent a good day trying to figure this out, I need help enabling tests
|
|
|
|
|
|
for aarch64.
|
|
|
|
|
|
|
|
|
|
|
|
Goal: run `bazel test //test/...` for 2 architectures: amd64 and arm64.
|
|
|
|
|
|
Arm64 would be executed under qemu-aarch64.
|
|
|
|
|
|
|
|
|
|
|
|
This works on my laptop (amd64/buster):
|
|
|
|
|
|
|
|
|
|
|
|
git clone https://git.sr.ht/~motiejus/bazel-zig-cc -b qemu
|
|
|
|
|
|
cd bazel-zig-cc; direnv allow .
|
|
|
|
|
|
bazel test --run_under=qemu-aarch64 \
|
|
|
|
|
|
--platforms @zig_sdk//:linux_arm64_platform \
|
|
|
|
|
|
--extra_toolchains @zig_sdk//:linux_arm64_musl_toolchain \
|
|
|
|
|
|
//test/go:go_test
|
|
|
|
|
|
|
|
|
|
|
|
Fails[1] on builds.sr.ht, which is also buster/amd64.
|
|
|
|
|
|
|
|
|
|
|
|
2022/02/04 09:21:03 fork/exec /home/<...>/go_test: exec format error
|
|
|
|
|
|
|
|
|
|
|
|
However, when executed directly via qemu-aarch64 on the given CI
|
|
|
|
|
|
machine, it works:
|
|
|
|
|
|
|
|
|
|
|
|
build@build:~/bazel-zig-cc$ qemu-aarch64 /<...>/go_test
|
|
|
|
|
|
PASS
|
|
|
|
|
|
build@build:~/bazel-zig-cc$
|
|
|
|
|
|
|
|
|
|
|
|
strace, investigating the bazel's sandboxing (I suspected this may be
|
|
|
|
|
|
caused by linux-sandbox-pid1.cc) didn't reveal anything. Any pointers?
|
|
|
|
|
|
|
|
|
|
|
|
Thanks,
|
|
|

Hi all,
|
|
|
|
|
|
|
|
|
|
|
|
Piotr Sikora replied out-of-band[1]. Two things needed to be changed:
|
|
|
|
|
|
|
|
|
|
|
|
1. Install binfmt-support. That registers qemu handlers to binfmt.
|
|
|
|
|
|
2. use qemu-aarch64-static instead of the shared version.
|
|
|
|
|
|
|
|
|
|
|
|
... and now we run all unit tests on both amd64 and arm64, and the test
|
|
|
|
|
|
runner[2] is less ugly.
|
|
|
|
|

Hi all,
|
|
|
|
|
|
|
|
|
|
|
|
bazel-zig-cc v0.4.4 is out. Major changes:
|
|
|
|
|
|
|
|
|
|
|
|
- register "bazel platforms" @zig_sdk//:<os>_<arch>_platform. Example
|
|
|
|
|
|
`--platform @zig_sdk//:linux_amd64_platform`. Note that this is in the
|
|
|
|
|
|
wrong place[1] and is likely to be changed.
|
|
|
|
|
|
- Tests are now executed[2] with `bazel test //test/...` on amd64
|
|
|
|
|
|
(natively) and arm64 (via qemu-aarch64-static). You are enocouraged to
|
|
|
|
|
|
add your own tests if you would like me to catch issues for you before
|
|
|
|
|
|
bumping zig-cc.
|
|
|
|
|
|
- I did NOT upgrade zig, it's the same as in v0.4.3.
|
|
|
|
|
|
|
|
|
|
|
|
Zig's maintainer Andrew asked me to test the 0.9.x release branch before
|
|
|
|
|
|
he does a zig 0.9.1 release. So if you care for zig not breaking
|
|
|
|
|
|
something before the release, but that doesn't really fit into zig's
|
|
|
|
|
|
test suite, a test in test/ may be a good place.
|
|
|
|
|
|

|

Hi all,
|
|
|
|
|
|
|
|
|
|
|
|
thanks to Ken Micklas contributions, bazel-zig-cc can now do the
|
|
|
|
|
|
following:
|
|
|
|
|
|
|
|
|
|
|
|
- support netrc authentication. You can use internal mirrors for zig
|
|
|
|
|
|
bundle now (assuming they support netrc, of course).
|
|
|
|
|
|
- provide multiple download urls for the zig toolchain via
|
|
|
|
|
|
`url_formats`. This option is now documented, among with `version` and
|
|
|
|
|
|
`sha256`.
|
|
|
|
|
|
- while at it, upgraded zig to 0.10.0-dev.1393+291f5055f. I will be
|
|
|
|
|
|
cleaning up pre-0.10.0 from dl.jakstys.lt, consider yourself warned.
|
|
|
|
|
|
|
|
|
|
|
|
Since `sha256`, `urls` and `version` are part of the "official" API, I
|
|
|
|
|
|
will not be upgrading zig in bazel-zig-cc (or, rather, will upgrade much
|
|
|
|
|
|
more rarely); please do so in your application.
|
|
|
|
|
|
|
|
|
|
|
|
Reminder: dl.jakstys.lt is a small machine in my home closet. No UPS, no
|
|
|
|
|
|
monitoring whatsoever. So, if you are depending on this for work, you
|
|
|
|
|
|
may want to use your mirror.
|
|
|
|
|
|
|
|
|
|
|
|
Happy compiling,
|
|
|
|
|
|
Motiejus

I was on the edge about this myself, since that would require us to
|

|
|
right, leaving it like this for reproducibility.

Hi all,
|
|
|
|
|
|
|
|
|
|
|
|
As I've received significant contributions from Ken Micklas and Laurynas
|
|
|
|
|
|
Lubys, I decided to grant them write access to bazel-zig-cc. Here is an
|
|
|
|
|
|
email I've sent them privately with the rules:
|
|
|
|
|
|
|
|
|
|
|
|
- When WIP, feel free to push your code to <your name>/<feature name>
|
|
|
|
|
|
branch. Remove the branch when done.
|
|
|
|
|
|
- When ready for merging, push it to the `next` branch and ping me.
|
|
|
|
|
|
- I will keep merging to `main`, tagging the releases keep emailing the
|
|
|
|
|
|
announcements.
|
|
|
|
|
|
|
|
|
|
|
|
That way, `main` will still have the latest tagged release signed by me.
|
|
|
|
|
|
|
|
|
|
|
|
I will also be talking about bazel-zig-cc in the upcoming Zig meetup
|
|
|
|
|
|
this weekend[1]. I was also listed in Google FOSS peer award and
|
|
|
|
|
|
"earned" $250 for bazel-zig-cc[2]. Thanks Google!
|

Hi all,
|
|
|
|
|
|
|
|
|
|
|
|
this change is a breaking change to bazel-zig-cc. Main points (from changelog):

### [laurynasl] Hide toolchain internals
|
|
|
|
|
|
|
|
|
|
|
|
This is a long-standing issue where platforms, toolchains and private stuff was
|
|
|
|
|
|
mixed together. Now platforms and toolchains are defined in their own
|
|
|
|
|
|
namespaces:

### [Ken Micklas] Upgrade to Bazel 5.1.0
|
|
|
|
|
|
|
|
|
|
|
|
... we now require minimal bazel 5.1.0. And there are some other minor
|
|
|
|
|
|
CI improvements, like specifying golang version for reproducibility.
|
|
|
|
|
|
|
|
|
|
|
|
Laurynas is preparing a different way to specify musl and glibc
|
|
|
|
|
|
platforms by selecting the platform, not the toolchain. This should
|
|
|
|
|
|
happen soon. This was desirable from day 0, but I couldn't make it
|
|
|
|
|
|
happen reliably at the time, so resorted to `--extra_toolchains`.
|
|
|
|
|
|
Looking forward to it!

Hi all,

Slight rule correction:

Since I allow for force-pushes, we have 3 contributors, `next` doesn't
|
|
|
|
|
|
make sense. So push to "your" branch (<your name>/<feature slug>) and
|
|
|
|
|
|
I'll merge from there.
|
|
|
|
|
|
|
|
|
|
|
|
So we should have only those branches in ~motiejus/bazel-zig-cc:
|
|
|
|
|
|
- `main`: passes CI and is always the latest released tag.
|
|
|
|
|
|
- for our sandbox work: `motiejus/<X>`, `laurynasl/<X>`,
|
|
|
|
|
|
`kmicklas/<X>`. You are the boss there.
|
|
|
|
|
|
|
|
|
|
|
|
There seems to be a problem with sourcehut picking the patches from the
|
|
|
|
|
|
mailing list, which I reported to `#sr.ht:libera.chat`:
|
|
|
|
|
|

|
UI-generated patchset
|
|
|
|
|

(https://lists.sr.ht/~motiejus/bazel-zig-cc/%3C164932427279.26543.1789507091630612744-0%40git.sr.ht%3E)
|
|
|
|
|
|
did not end up in https://lists.sr.ht/~motiejus/bazel-zig-cc/patches
|
|
|
|
|
|
and, consequently, did not trigger a CI run. Is this appropriate
|
|
|
|
|
|
place to report it? Happened ~1 hour ago.

Looks like this slipped through the CI. We should think about how to
|
|
|
|
|
|
catch cases like these.

I think the next step, where you suggested replacing
|
|
|
|
|
|
`--extra_toolchains` with
|
|
|
|
|
|
registering-all-toolchains-and-specifying-the-platforms, would have
|
|
|
|
|
|
helped here?
|
|
|
|
|
|
|
|
|
|
|
|
Once transitioned to platforms, I expect us to stop specifying the
|
|
|
|
|
|
`--extra_toolchains` and only use platform constraints. Then write a
|
|
|
|
|
|
couple of test targets and confirm they are building artifacts for
|
|
|
|
|
|
correct architectures
|
|
|
|
|
|
|
|
|
|
|
|
Transitions can even allow `sh_test` targets, which would run `file` on
|
|
|
|
|
|
the output binary and assert it's architecture. The `ci/test` script
|
|
|
|
|
|
would become even simpler.

Hi all,
|
|
|
|
|
|
|
|
|
|
|
|
Laurynas rewrote bazel-zig-cc. Now it will support specifying
|
|
|
|
|
|
arch/os/libc via *platforms* alone (provided toolchains are registered).
|
|
|
|
|
|
E.g.
|
|
|
|
|
|
|
|
|
|
|
|
--platforms @zig_sdk//libc_aware/platform:linux_amd64_gnu.2.28
|
|
|
|
|
|
--platforms @zig_sdk//libc_aware/platform:linux_amd64_musl
|
|
|
|
|
|
|
|
|
|
|
|
I intend to merge this on ~Tuesday. There will be (almost) no breaking
|
|
|
|
|
|
changes, but many new ways to use bazel-zig-cc. I am excited about this
|
|
|
|
|
|
release, as now it makes many things "right". Read the README. :)
|
|
|
|
|
|
|
|
|
|
|
|
While updating documentation, I accidentally wrote my mental model on
|
|
|
|
|
|
how `--platforms`, `--toolchains` and constraints interact. If you find
|
|
|
|
|
|
lies there, please let me know, I will un-lie them.
|
|
|
|
|
|
|
|
|
|
|
|
Here are the updated docs; notice they are much longer than the
|
|
|
|
|
|
original:
|
|
|
|
|
|
https://git.sr.ht/~motiejus/bazel-zig-cc/tree/laurynasl_libc/item/README.md?view-rendered
|
|
|
|
|
|
|
|
|
|
|
|
Thanks Laurynai!

Hi all,
|
|
|
|
|
|
|
|
|
|
|
|
I've released bazel-zig-cc v0.7.0. It's a rewrite by laurynasl@ and
|
|
|
|
|
|
major documentation upgrade by myself.
|
|
|
|
|
|
|
|
|
|
|
|
Incompatible changes
|
|
|
|
|
|
--------------------
|
|
|
|
|
|
|
|
|
|
|
|
1. `register_toolchains` renamed to `toolchains`. Before:
|
|
|
|
|
|
|
|
|
|
|
|
load("@bazel-zig-cc//toolchain:defs.bzl", zig_register_toolchains = "register_toolchains")
|
|
|
|
|
|
|
|
|
|
|
|
After:
|
|
|
|
|
|
|
|
|
|
|
|
load("@bazel-zig-cc//toolchain:defs.bzl", zig_toolchains = "toolchains")
|
|
|
|
|
|
|
|
|
|
|
|
2. `toolchains(register = ...)` was removed. You should be registering
|
|
|
|
|
|
the toolchains directly in the WORKSPACE or via `.bazelrc` (see README).
|
|
|
|
|
|
|
|
|
|
|
|
3. "glibc version autodetection" is removed: the glibc version must now
|
|
|
|
|
|
be always specified.
|
|
|
|
|
|
|
|
|
|
|
|
New Features
|
|
|
|
|
|
------------
|
|
|
|
|
|
|
|
|
|
|
|
1. Now one can specify the libc variant (glibc+version or libc) via
|
|
|
|
|
|
`--platforms` alone. See README.
|
|
|
|
|
|
|
|
|
|
|
|
2. Internal: more examples with multiple architectures, transitions, and
|
|
|
|
|
|
a new "C" test case.
|
|
|
|
|
|
|
|
|
|
|
|
Ecosystem
|
|
|
|
|
|
---------
|
|
|
|
|
|
|
|
|
|
|
|
While testing this internally, we've realized that the new version of
|
|
|
|
|
|
rules_docker[1] is not compatible with the new libc-in-the-platform
|
|
|
|
|
|
feature, since the libc version is *part of the platform now*. Laurynas
|
|
|
|
|
|
will comment in the PR with more details.
|
|
|
|
|
|
|
|
|
|
|
|
Enjoy!

|
|
|
|
Regarding rules_docker:
|
|
|
|
|
|
|
|
|
|
|
|
In 0.23.0, rules_docker added transitions based on the architecture
|
|
|
|
|
|
and operating system specified on the container_image. The platform
|
|
|
|
|
|
transition is "hard-coded" in a sense where it will use a specific
|
|
|
|
|
|
platform that only includes the os and cpu constraints. This means
|
|
|
|
|
|
that it is not possible to provide a platform which includes a libc
|
|
|
|
|
|
version. There seem to still be some discussion on how this should
|
|
|
|
|
|
best be solved in rules_docker.
|
|
|
|

Cheers,

Hi everyone,
|
|
|
|
|
|
|
|
|
|
|
|
I just cut bazel-zig-cc v0.7.1, which adds a workaround for the infamous
|
|
|
|
|
|
libc linking problem:
|
|
|
|
|
|
|
|
|
|
|
|
net(.text): relocation target __errno_location not defined
|
|
|
|
|
|
net(.text): relocation target getaddrinfo not defined
|
|
|
|
|
|
<...>
|
|
|
|
|
|
|
|
|
|
|
|
Read about it, as well as related issues, in this github summary[1].
|
|
|
|
|
|
Many thanks to Andrew Kelley and Ken Micklas for working on it!
|
|
|
|
|
|
|
|
|
|
|
|
What is the cause? Because `zig cc` adds `--gc-sections` to the `ld.lld`
|
|
|
|
|
|
flags, which does not play well with cgo. So the workaround adds
|
|
|
|
|
|
`--no-gc-sections` to the linker flags for the time being.

Hi all,
|
|
|
|
|
|
|
|
|
|
|
|
It was a long time ago since the last Zig SDK update. I just released
|
|
|
|
|
|
v0.7.2, which updates the zig to tonight's build
|
|
|
|
|
|
zig-0.10.0-dev.2252+a4369918b, along with bazel-zig-cc's test
|
|
|
|
|
|
dependencies (rules_go, bazel-gazelle, golang).
|
|
|
|
|
|
|
|
|
|
|
|
Also, I removed many prehistorical zig-sdk versions from the
|
|
|
|
|
|
dl.jakstys.lt mirror and left only the ones referenced by v0.7.1 and
|
|
|
|
|
|
v0.7.2. If your build broke as a result, it's a good time to reconsider
|
|
|
|
|
|
hosting zig sdk yourself.
|
|
|
|
|
|
|
|
|
|
|

|
|

Hello there,
|
|
|
|
|
|
|
|
|
|
|
|
First of all, thank you for this great project! I was always intrigued
|
|
|
|
|
|
by zig's C/C++ compilation abilities but wasn't too keen on adopting it
|
|
|
|
|
|
as a build system. Being able to use zig as a bazel toolchain using this
|
|
|
|
|
|
project is incredible and exactly the way I always wanted to use zig.
|
|
|
|
|
|
|
|
|
|
|
|
My intended use case for bazel-zig-cc was to enable cross compilation
|
|
|
|
|
|
between the two supported platforms Linux and Windows in my project [1].
|
|
|
|
|
|
To this end, I started looking into extending bazel-zig-cc with Windows
|
|
|
|
|
|
support both as a host and target system. The attached three commits in
|
|
|
|
|
|
made this work and successfully allowed me to cross compile all of my
|
|
|
|
|
|
cc_binary targets between Linux and Windows using zig cc. That said,
|
|
|
|
|
|
they do not actually depend on each other and can be used individually.
|
|
|
|
|
|
I hope others might find them useful, too, and would like to ask you to
|
|
|
|
|
|
consider accepting them into the mainline of the project.
|
|
|
|
|
|
|
|
|
|
|
|
Best,
|
|
|
|
|
|
Fabian

This commit adds support for Windows as a host system. For example, given
|
|
|
|
|
|
an existing bazel project on Windows, this commit enables cross
|
|
|
|
|
|
compilation to other supported target platforms of bazel-zig-cc such as
|
|
|
|
|
|
Linux. I've successfully used it to cross compile a Linux cc_binary from a
|
|
|
|
|
|
Windows machine and validated that it works correctly by copying it to a
|
|
|
|
|
|
Linux box and launching it there.
|
|
|
|
|
|
|
|
|
|
|
|
Apart from downloading the correct zig SDK version on Windows, the main
|
|
|
|
|
|
crux here was to actually make all of the zig tools properly executable.
|
|
|
|
|
|
In order for the wrapper script to be executable, it needs to be a batch
|
|
|
|
|
|
script with the proper extension instead of bash. Further, the actual
|
|
|
|
|
|
zig binary itself is called zig.exe instead of just zig on Windows.

This commit adds support for Windows targets to bazel-zig-cc by
|
|
|
|
|
|
registering the appropriate toolchains and platforms for it. I've
|
|
|
|
|
|
validated this by building a cc_binary on Linux targeting
|
|
|
|
|
|
the windows_amd64 platform/toolchain combination, copying the resulting
|
|
|
|
|
|
binary to a Windows box and successfully executing it there. I was also
|
|
|
|
|
|
able to run the resulting binary under wine.
|
|
|
|
|
|
|
|
|
|
|
|
One thing to note is that even though cross compilation builds work
|
|
|
|
|
|
completely fine, the resulting build outputs are named .a for static
|
|
|
|
|
|
libraries (instead of .lib), .so for dynamic libraries (instead of
|
|
|
|
|
|
.dll), and have no extension for executables (instead of .exe). I tried
|
|
|
|
|
|
to find out why this is but unfortunately couldn't figure it out. That
|
|
|
|
|
|
said, the resulting binaries work completely fine.

This commit adds a constraint_setting that can be used to select()
|
|
|
|
|
|
between builds with and without zig cc. The reason I added this is
|
|
|
|
|
|
because I found that selecting on @bazel_tools//platforms:windows is not
|
|
|
|
|
|
enough for Windows builds since that constraint value alone will match
|
|
|
|
|
|
both native builds using the MSVC compiler as well as builds using zig
|
|
|
|
|
|
cc. The problem arises when passing custom compiler on linker flags that
|
|
|
|
|
|
differ in syntax between MSVC and zig's clang format. For example, to

link the gdi32 system library on Windows MSVC expects the argument
|
|
|
|
|
|
"-DEFAULTLIB:gdi32.lib". However, with zig cc this needs to be "-lgdi32"
|
|
|
|
|
|
instead. Having the additional constraint setting for the bazel-zig-cc
|
|
|
|
|
|
platforms allows you to define more specific config settings such as:
|
|
|
|
|
|
|
|
|
|
|
|
config_setting(
|
|
|
|
|
|
name = "windows",
|
|
|
|
|
|
constraint_values = [
|
|
|
|
|
|
"@bazel_tools//platforms:windows",
|
|
|
|
|
|
"@zig_sdk//platform:zig_cc_disabled",
|
|
|
|
|
|
],
|
|
|
|
|
|
)
|
|
|
|
|
|
|
|
|
|
|
|
config_setting(
|
|
|
|
|
|
name = "windows_zig",
|
|
|
|
|
|
constraint_values = [
|
|
|
|
|
|
"@bazel_tools//platforms:windows",
|
|
|
|
|
|
"@zig_sdk//platform:zig_cc_enabled",
|
|
|
|
|
|
],
|
|
|
|
|
|
)
|
|
|
|
|
|
|
|
|
|
|
|
This can then be used to switch between linker options as follows:
|
|
|
|
|
|
cc_binary(
|
|
|
|
|
|
# [...]
|
|
|
|
|
|
linkopts = select({
|
|
|
|
|
|
":windows": ["-DEFAULTLIB:gdi32.lib"],
|
|
|
|
|
|
":windows_zig": ["-lgdi32"],
|
|
|
|
|
|
}),
|
|
|
|
|
|
)
