Created attachment 843297 [details] dev-lang/zig-0.10.0's build.log CMake Error at cmake/Findllvm.cmake:90 (continue): A CONTINUE command was found outside of a proper FOREACH or WHILE loop scope. Call Stack (most recent call first): cmake/Findllvm.cmake:93 (NEED_TARGET) CMakeLists.txt:138 (find_package) this is cmake's error; attached to this bug is the full build.log

It's very rarely useful but could you include /var/tmp/notmpfs/portage/dev-lang/zig-0.10.0/work/zig-0.10.0/build/CMakeFiles/CMakeOutput.log for completeness just because this might be more of a weird CMake internal thing?

At 237 line in "emerge-info.log" there is this line > LLVM_TARGETS="X86" Does this mean that other LLVM_TARGETS are disabled for `sys-devel/llvm`? Zig expects all targets to be enabled

It's about how Zig compiler designed, with stuff like "cross-compilation out-of-box" (which means they enable all targets for LLVM and it's easier for them to expect from other people same), consistency etc. In your "CMakeOurput.log" there is hint for 93 line in "cmake/Findllvm.cmake": > NEED_TARGET("AArch64") Amd above there is what should be printed when target is not found: > # Save the error message, in case this is the last llvm-config we find > list(APPEND LLVM_CONFIG_ERROR_MESSAGES "LLVM (according to ${LLVM_CONFIG_EXE}) is missing target ${TARGET_NAME}. Zig requires LLVM to be built with all default targets enabled.") > # Ignore this directory and try the search again > list(APPEND CMAKE_IGNORE_PATH "${LLVM_CONFIG_DIR}") > continue() Somehow error is not printed and "continue()" leads to the error. I'm not so good at CMake writing, so I'll fix it tomorrow (and send to upstream ofc) [if it is not bug in CMake or installed CMake files for llvm]
May be regression since https://github.com/ziglang/zig/commit/3f640ef3d20db848a4d38299cb66db8a3c14b3b1
