Here's the doc comment from the commit: For one example of why this is handy, consider the case of building musl libc. We keep a lock open for each of the object files in the form of a file descriptor until they are finally put into an archive file. This is to allow a zig-cache garbage collector to run concurrently to zig processes, and to allow multiple zig processes to run concurrently with each other, without clobbering each other. This code is disabled until #6361 is implemented (getrlimit/setrlimit are not yet added to the standard library).
A general-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.

Building from Source
Note that you can download a binary of master branch or install Zig from a package manager.
Stage 1: Build Zig from C++ Source Code
Dependencies
POSIX
- cmake >= 2.8.5
- gcc >= 5.0.0 or clang >= 3.6.0
- LLVM, Clang, LLD development libraries == 10.x, compiled with the same gcc or clang version above
- Use the system package manager, or build from source.
Windows
- cmake >= 3.15.3
- Microsoft Visual Studio. Supported versions:
- 2015 (version 14)
- 2017 (version 15.8)
- 2019 (version 16)
- LLVM, Clang, LLD development libraries == 10.x
- Use the pre-built binaries or build from source.
Instructions
POSIX
mkdir build
cd build
cmake ..
make install
Need help? Troubleshooting Build Issues
MacOS
brew install cmake llvm
brew outdated llvm || brew upgrade llvm
mkdir build
cd build
cmake .. -DCMAKE_PREFIX_PATH=$(brew --prefix llvm)
make install
You will now run into this issue:
homebrew and llvm 10 packages in apt.llvm.org are broken with undefined reference to getPollyPluginInfo
or
error: unable to create target: 'Unable to find target for this triple (no targets are registered)',
in which case try -DZIG_WORKAROUND_4799=ON
Hopefully this will be fixed upstream with LLVM 10.0.1.
Windows

License
The ultimate goal of the Zig project is to serve users. As a first-order effect, this means users of the compiler, helping programmers to write better code. Even more important, however, are the end users.
Zig is intended to be used to help end users accomplish their goals. For example, it would be inappropriate and offensive to use Zig to implement dark patterns and it would be shameful to utilize Zig to exploit people instead of benefit them.
However, such problems are best solved with social norms, not with software licenses. Any attempt to complicate the software license of Zig would risk compromising the value Zig provides to users.
Therefore, Zig is available under the MIT (Expat) License, and comes with a humble request: use it to make software better serve the needs of end users.
