Building from Source

Note that you can download a binary of master branch.

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brew outdated llvm || brew upgrade llvm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.
