Description Mamadou Babaei 2024-12-27 17:26:13 UTC

When I do the following, it fails to build (otherwise it builds):

echo 'llvm-core/clang-common default-compiler-rt default-libcxx default-lld' > /etc/portage/package.use/llvm-core_clang-common
echo 'llvm-core/clang default-compiler-rt default-libcxx static-analyzer WebAssembly' > /etc/portage/package.use/llvm-core_clang
echo 'llvm-core/clang-runtime compiler-rt -crt libcxx openmp sanitize' > /etc/portage/package.use/llvm-core_clang-runtime
echo 'llvm-core/llvm -exegesis gold libedit libffi ncurses sanitize xar xml WebAssembly' > /etc/portage/package.use/llvm-core_llvm
echo 'llvm-runtimes/compiler-rt clang' > /etc/portage/package.use/llvm-runtimes_compiler-rt
echo 'llvm-runtimes/libcxx -clang libcxxabi -libcxxrt -libunwind' > /etc/portage/package.use/llvm-runtimes_libcxx
echo 'llvm-runtimes/libcxxabi -clang -libunwind' > /etc/portage/package.use/llvm-runtimes_libcxxabi
echo '# abi_x86_32 abi_x86_64 is a remedy for https://bugs.gentoo.org/834490' > /etc/portage/package.use/sys-libs_libunwind
echo 'sys-libs/libunwind abi_x86_32 abi_x86_64 debug-frame -libatomic lzma static-libs' >> /etc/portage/package.use/sys-libs_libunwind

# static libs are required with libs that statically depend on libunwind
echo 'app-arch/xz-utils static-libs' > /etc/portage/package.use/app-arch_xz-utils
echo 'sys-libs/zlib static-libs' > /etc/portage/package.use/sys-libs_zlib

emerge -atuv llvm-core/llvm llvm-core/clang llvm-core/lldb llvm-core/lld
emerge -1atv app-arch/xz-utils sys-libs/zlib
