std.os.execvpeZ_expandArg0: fix not restoring argv[0] 
This function expands argv[0] into the absolute path resolved with PATH
environment variable before making the execve syscall. However, in case
the execve fails, e.g. with ENOENT, it did not restore argv to how it
was before it was passed in. This resulted in the caller performing an
invalid free.

This commit also adds verbose debug info when native system C compiler
detection fails. See #4521.

Building from Source

Build Status

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 == 9.x, compiled with the same gcc or clang version above
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 == 9.x

Instructions

POSIX
mkdir build
cd build
cmake ..
make install
MacOS
brew install cmake llvm@9
brew outdated llvm@9 || brew upgrade llvm@9
mkdir build
cd build
cmake .. -DCMAKE_PREFIX_PATH=$(brew --prefix llvm)
make install
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
