Similar to https://github.com/ziglang/zig/issues/11137, and it may be caused by detecting the wrong libc version, like https://github.com/ziglang/zig/issues/6469, but this is prefix, so maybe zig is looking into hosts' libc
Update: On another prefix with Debian host (the original bug report is produced on RHEL 8 host where /lib64 -> /usr/lib64 contains libm.so and other libraries), the error messages are: ``` FAILED: stage3/bin/zig /fast/portage/dev-lang/zig-0.11.0/work/zig-0.11.0/build/stage3/bin/zig cd /fast/portage/dev-lang/zig-0.11.0/work/zig-0.11.0 && /fast/portage/dev-lang/zig-0.11.0/work/zig-0.11.0/build/zig2 build --prefix /fast/portage/dev-lang/zig-0.11.0/work/zig-0.11.0/build/stage3 --zig-lib-dir /fast/portage/dev-lang/zig-0.11.0/work/zig-0.11.0/lib -Dconfig_h=/fast/portage/dev-lang/zig-0.11.0/work/zig-0.11.0/build/config.h -Denable-llvm -Doptimize=ReleaseFast -Dno-langref -Dno-autodocs -Dtarget=native -Dcpu=native -Dversion-string=0.11.0 zig build-exe zig ReleaseFast native: error: the following command failed with 1 compilation errors: /fast/portage/dev-lang/zig-0.11.0/work/zig-0.11.0/build/zig2 build-exe --stack 33554432 /fast/portage/dev-lang/zig-0.11.0/work/zig-0.11.0/src/main.zig /fast/portage/dev-lang/zig-0.11.0/work/zig-0.11.0/build/zigcpp/libzigcpp.a /opt/gentoo/usr/lib/llvm/16/lib64/libclang-cpp.so.16 /opt/gentoo/usr/lib/llvm/16/lib64/liblldMinGW.so /opt/gentoo/usr/lib/llvm/16/lib64/liblldELF.so /opt/gentoo/usr/lib/llvm/16/lib64/liblldCOFF.so /opt/gentoo/usr/lib/llvm/16/lib64/liblldWasm.so /opt/gentoo/usr/lib/llvm/16/lib64/liblldMachO.so /opt/gentoo/usr/lib/llvm/16/lib64/liblldCommon.so /opt/gentoo/usr/lib/llvm/16/lib64/libLLVM-16.so /opt/gentoo/usr/lib/gcc/x86_64-pc-linux-gnu/13/libstdc++.so -lunwind -lc -OReleaseFast --cache-dir /fast/portage/dev-lang/zig-0.11.0/work/zig-0.11.0/zig-cache --global-cache-dir /fast/portage/dev-lang/zig-0.11.0/homedir/.cache/zig --name zig --mod build_options::/fast/portage/dev-lang/zig-0.11.0/work/zig-0.11.0/zig-cache/c/8be3380d7aa95aa051fdfc613f919a48/options.zig --deps build_options -I /opt/gentoo/usr/lib/llvm/16/include -I /opt/gentoo/usr/lib/llvm/16/include -L /opt/gentoo/usr/lib/llvm/16/lib64 -I /opt/gentoo/usr/lib/llvm/16/include --zig-lib-dir /fast/portage/dev-lang/zig-0.11.0/work/zig-0.11.0/lib --listen=- Build Summary: 2/5 steps succeeded; 1 failed (disable with --summary none) install transitive failure +- install zig transitive failure +- zig build-exe zig ReleaseFast native 1 errors error: ld.lld: cannot open /lib64/libm.so.6: No such file or directory ``` So it's more evident that something goes wrong when zig detects system lib locations
Can you share output of: * getconf GNU_LIBC_VERSION * zig2 build-exe --show-builtin on both systems please? Thanks in advance!

I see, thanks! Guess I need to return getconf patch for a while.

Sorry, after applying the patch, the `./zig2 build-exe --show-builtin` command shows glibc version to 2.36, but not 2.37 which is the output of `getconf GNU_LIBC_VERSION`. And the build error remains the same. And I noticed that, before applying this patch, both system `./zig2 build-exe --show-builtin` gives glibc version 2.19, despite the Gentoo prefix has 2.37, while RHEL 8 has 2.19 and Debian 12 has 2.36. After the patch, `./zig2 build-exe --show-builtin` both gives 2.36. It looks very weird. I will add the output prefixed with "new-" in attachments.

Above are my test results after the fix, and I didn't notice any new commit introduced to dev-lang/zig-0.11.0 since then. So I guess the issue is still here.

Yes, I was using https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=54b20cb55a644f07faa7f426118e4ff9b6c4d8e9 which contains the two new commits, and I also confirms that dev-lang/zig-9999 has new `llvm` use flag in my tree.
