https://github.com/Infrasonics/eselect-llvm or gcc-config alike all the easier seems they canned the eslect-llvm idea ??? ... else like crossdev gcc-config/eselect-llvm /opt/rpi5-genpi , chroot bang out bins rsync binhost n done .. eselect-llvm seems it could have in theory handled swapping from systems-llvm/clang to llvm-mingw and back to systemsset ... forgoing need of doing symlinks etc ie # Create relative symlinks for clang mingw binaries for system clang folders etc ... but as i gathered registry file in each $pv llvm ... seen article mentioning or new updates on emerge eons ago... # Create relative symlinks for clang mingw binaries this likely would need filtering as to not clober the system clang but symlink libs , and commandeered items to extend the system-llvm/clang appropriately ie clang-mingw-$pv into system clang else a bash script derivation of sys-devel/clang-toolchain-symlinks as sys-devel/clang-toolchain-symlinks-mingw for arm64 gcc crossdev styled symlinks for GCC if wanted /fix clang-llvm--mingw-gcc symlinks as needed FLAG="msvcrt FLAG="ucrt" some time ago this was quite Arch specific ie arm64/AMD64 @@@@ a Caveat i might have forgotten ? @@@@ # Determine the correct tarball based on USE flags ### Enjoy ... .
