If dev-lang/rust-1.79.0 is compiled with "wasm", it fails with the error: failed to run custom build command for `compiler_builtins v0.1.109` (The command itself is a bit long, so look for yourself in the attached build.log)
You have failed to attach the build log. Please also provide emerge --info.

(In reply to Mike Gilbert from comment #1) > You have failed to attach the build log. Please also provide emerge --info. Yeah, sorry about that. I guess I am either stupid or it didn't upload because it was larger than the upload limit.

Following that link, I tried: Enabling 'system-llvm' doesn't help, probably due to: https://bugs.gentoo.org/735154 I modified the ebuild so the [llvm] section has clang = false and the wasm target has cc = "${CHOST}-clang" and cxx = "${CHOST}-clang++" That also didn't work, same errors: [compiler_builtins 0.1.123] error occurred: Command "x86_64-pc-linux-gnu-clang" "-O3" "-ffunction-sections" "-fdata-sections" "-fPIC" "--target=wasm32-unknown-unknown" "-ffunction-sections" "-fdata-sections" "-fPIC" "--target=wasm32-unknown-unknown" "-pipe" "-mno-cldemote" "-mno-kl" "-mno-sgx" "-mno-widekl" "-mshstk" "--param=l1-cache-line-size=64" "--param=l1-cache-size=32" "--param=l2-cache-size=36864" "-fno-builtin" "-fvisibility=hidden" "-ffreestanding" "-DCOMPILER_RT_HAS_FLOAT16" "-DVISIBILITY_HIDDEN" "-o" "/var/tmp/portage/dev-lang/rust-1.82.0/work/rustc-1.82.0-src/build/x86_64-unknown-linux-gnu/stage2-std/wasm32-unknown-unknown/release/build/compiler_builtins-8e0c09697ead9752/out/98bdc0515731792f-absvdi2.o" "-c" "/var/tmp/portage/dev-lang/rust-1.82.0/work/rustc-1.82.0-src/src/llvm-project/compiler-rt/lib/builtins/absvdi2.c" with args x86_64-pc-linux-gnu-clang did not execute successfully (status code exit status: 1).

At some point I'll probably need to update, not sure what I'll do then as I haven't a clue how to solve this. For others with this same problem, you'll also need to mask these as they require later versions of rust: >sys-apps/fd-9.9.9 >www-client/chromium-126.0.6478.126 >dev-util/cargo-c-0.10.0
