I have built zig from source before successfully, but now I am stumped. I get a segfault on the step where it builds or is using zig stage3 (I can’t tell which it is).
I use a combination of these instructions:
- How to build LLVM, libclang, and liblld from source · ziglang/zig Wiki · GitHub
- Building Zig From Source · ziglang/zig Wiki · GitHub
Which produces the following procedure:
(I am on x86_64-linux debian 12)
LLVM Build
cd ~/Downloads
# wipe the whole build state
rm -rf llvm-project-20
# wipe my llvm install
rm -rf ~/local/llvm20-assert/
git clone --depth 1 --branch release/20.x https://github.com/llvm/llvm-project llvm-project-20
cd llvm-project-20
git checkout release/20.x
mkdir build-release
cd build-release
cmake ../llvm \

-DCMAKE_BUILD_TYPE=Release \
-DLLVM_ENABLE_PROJECTS="lld;clang" \
-DLLVM_ENABLE_LIBXML2=OFF \
-DLLVM_ENABLE_TERMINFO=OFF \
-DLLVM_ENABLE_LIBEDIT=OFF \
-DLLVM_ENABLE_ASSERTIONS=ON \
-DLLVM_PARALLEL_LINK_JOBS=1 \
-G Ninja
ninja install
The LLVM build seems to work fine, it just takes 3 hours and I can’t use my browser otherwise it will OOM.
I did this today. So it should be the most recent llvm 20.x

I can build just fine on another machine (WSL2 on windows). Not sure what I have done wrong here.
Things I have checked:
- LLVM config output shows detected c and cpp compilers are correct (GNU 12.2.0) and is above the minimum required on zig build from source instructions
- Zig build config output shows correctly detected c, cpp, and llvm. (GNU 12.2.0 again). The llvm build and the zig build used the same cmake, c, and cpp compilers, as required by the zig build from source instructions.
- I deleted the LLVM install before I rebuilt and install LLVM to
~/local/llvm20-assert/ - I am not aware of any addtional caching mechanism / state that I need to wipe between builds.
