Zig Version

0.11.0-dev.809+b911b54ae

Steps to Reproduce and Observed Behavior

  1. compile LLVM 15 from source and install to /home/nunzio/local/llvm15-release/
  2. compile zstd from source and install to same prefix (not sure this actually matters, was trying to debug when I did this)
  3. git clone https://github.com/ziglang/zig
  4. cd zig
  5. git checkout b911b54 (latest CI passed commit when I cloned)
  6. mkdir build
  7. cmake .. -DCMAKE_PREFIX_PATH=$HOME/local/llvm15-release -DCMAKE_INSTALL_PATH=$HOME/local/zig
  8. make install

First got:

cd /home/nunzio/Repos/zig && /home/nunzio/Repos/zig/build/zig1 /home/nunzio/Repos/zig/lib build-exe src/main.zig -ofmt=c -lc -OReleaseSmall --name zig2 -femit-bin="/home/nunzio/Repos/zig/build/zig2.c" --
pkg-begin build_options /home/nunzio/Repos/zig/build/config.zig --pkg-end -target amd64-freebsd
error: UnknownArchitecture
[2/6] cd /home/nunzio/Repos/zig && /home/nunzio/Repos/zig/build/zig1 /home/nunzio/Repos/zig/lib build-obj lib/compiler_rt.zig -ofmt=c -OReleaseSmall --name compiler_rt -femit-bin="/home/nunzio/Repos/zig/
build/compiler_rt.c" --pkg-begin build_options /home/nunzio/Repos/zig/build/config.zig --pkg-end -target amd64-freebsd

Then after I forced the arch to be x86_64 I got:

Expected Behavior

I expected it to build. My solution:

  1. nano CMakeFiles/zig2.dir/build.make (replace amd64 with x86_65)
  2. nano ./CMakeFiles/stage3.dir/build.make (add -Duse-zig-libcxx=true to build compile line)
  3. nano cmake_install.cmake add -Duse-zig-libcxx=true to ZIG_BUILD_ARGS
  4. make install

Here's my uname -a:

FreeBSD <host> 13.1-RELEASE FreeBSD 13.1-RELEASE releng/13.1-n250148-fc952ac2212 GENERIC amd64

Looking forward to playing with zig, thank you for all of the hard work!

Update: I tried to use https://github.com/ratfactor/ziglings to get started with learning zig and discovered I have a non-funcitonal build:

If I use the stage2 compiler, it appears to work (I get the first error message that I'm supposed to fix).

see #13699

I'm holding off pushing a rebase of the PR until I work out linking system c++ standard library for stage3 for more than just FreeBSD.

btw,

  • unknown arch; solved in PR commit cmake: CMAKE_HOST_SYSTEM_PROCESSOR ignore case
  • panic incorrect alignment; solved in a commit I haven't pushed to the PR yet; fixes std.heap.rawCAlloc

Thanks for the heads up, I've subscribed to your PR. I'll re-check this once it's merged.

Now that #13699 is merged I will give this another try when I get a chance. Thank you @mikdusan!

Both of my issues are resolved in master, thanks again!
