* caching system: use 16 bytes siphash final(), there was a bug in the std lib that wasn't catching undefined values for 18 bytes. fixed in master branch. * fix caching system unit test logic to not cause error.TextBusy on windows * port the logic from stage1 for building glibc shared objects * add is_native_os to the base cache hash * fix incorrectly freeing crt_files key (which is always a reference to global static constant data) * fix 2 use-after-free in loading glibc metadata * fix memory leak in buildCRTFile (errdefer instead of defer on arena)
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

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brew outdated llvm || brew upgrade llvm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.
