Motiejus Jakštys 79674a1d96 replace /usr/bin/env sh with /bin/sh 
/bin/sh exists in NixOS and in fact is the only file in `/bin`:

    $ docker run -ti --rm nixos/nix ls /bin /usr/bin
    /bin:
    sh

    /usr/bin:
    env

Motiejus Jakštys 15f9578591 use a specific template if cache prefix is known 2022-08-26 10:55:29 +03:00
Ken Micklas 0612c6ed9c Support configuring cache prefix with an environment variable 
The user may want to build with `--sandbox_tmpfs_path=/tmp`, in which
case the Zig cache will not be shared between sandboxes, massively
slowing down the build. With this feature, the user can pass flags
like `--repo_env=BAZEL_ZIG_CC_CACHE_PREFIX=$HOME/.cache/bazel-zig-cc`
together with `--sandbox_writable_path=$HOME/.cache/bazel-zig-cc` to
put the cache somewhere else which can be shared between sandboxes.

Motiejus Jakštys db7beefbe4 c++: fall back to cache dir in /tmp 
rules_go is making calls that do `env - <...>` and are setting neither
TMPDIR nor HOME. So we should always fallback somewhere.

Motiejus Jakštys e50d1597f4 upgrade zig sdk to one of last night 2022-08-12 05:38:34 +03:00
Luis Holanda c4125cf13b Support NixOS and others non-FHS Linux distros 
As it expects Bash to be at `/bin/bash`, the current implementation
fails to execute on NixOS, given that there bash is in a non-standard
path (i.g. `/nix/store/<hash>-bash-interactive-<version>/bin/bash`).

This patch specifically changes `/bin/bash` paths to use `/usr/bin/env bash`,
which should give the correct path in every Unix system.

Motiejus Jakštys 8fec0e3441 zig sdk: download from zig upstream as well as jakstys.lt 
Now that the toolchain supports multiple mirrors, we can have more
robust defaults: try ziglang.org first, then dl.jakstys.lt when that one
removes the build we rely on.

This will make builds less prone to inevitable failures of my home
server.

Motiejus Jakštys 9ce21b5276 [zig ld] --gc-sections workaround + tests 
`zig cc` emits `--gc-sections` for the linker, which is incompatbile
with what CGo thinks about linking.

This commit adds a workaround: it will add `--no-gc-sections` to the
linking step if the command is not specified (falling back to the
default behavior of gcc/clang).
