This is the beginning of supporting minimum GLIBC version as part of the target. See #2509 for the motivation. The dummy libc zig files are removed. A future commit will build them on-the-fly, using the generated text files generated by the new tool, which are checked into source control and distributed along with zig. These generated text files are, together, 142KB (20KB gzipped). Compare that to a naive bundling of the .abilist files, which would be 2.2MiB (375KB gzipped). This is based on glibc 2.29.
Zig is an open-source programming language designed for robustness, optimality, and maintainability.
Resources
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 == 8.x, compiled with the same gcc or clang version above
- Use the system package manager, or build from source.
Windows
- cmake >= 2.8.5
- Microsoft Visual Studio 2017 (version 15.8)
- LLVM, Clang, LLD development libraries == 8.x, compiled with the same MSVC version above
- Use the pre-built binaries or build from source.
Instructions
POSIX
mkdir build
cd build
cmake ..
make install
MacOS
brew install cmake llvm@8
brew outdated llvm@8 || brew upgrade llvm@8
mkdir build
cd build
cmake .. -DCMAKE_PREFIX_PATH=/usr/local/Cellar/llvm/8.0.0_1
make install
Windows
See https://github.com/ziglang/zig/wiki/Building-Zig-on-Windows
Stage 2: Build Self-Hosted Zig from Zig Source Code
Note: Stage 2 compiler is not complete. Beta users of Zig should use the Stage 1 compiler for now.
Dependencies are the same as Stage 1, except now you can use stage 1 to compile Zig code.
bin/zig build --prefix $(pwd)/stage2
This produces ./stage2/bin/zig which can be used for testing and development.
Once it is feature complete, it will be used to build stage 3 - the final compiler
binary.
Stage 3: Rebuild Self-Hosted Zig Using the Self-Hosted Compiler
Note: Stage 2 compiler is not yet able to build Stage 3. Building Stage 3 is not yet supported.
Once the self-hosted compiler can build itself, this will be the actual compiler binary that we will install to the system. Until then, users should use stage 1.
Debug / Development Build
./stage2/bin/zig build --prefix $(pwd)/stage3
Release / Install Build
./stage2/bin/zig build install -Drelease
