bug#63238: issue linking to librt
librt and libpthread were merged into libc with glibc 2.34, however, for compatibility, there exist empty .a files to satisfy the linker. But because Guix has a separate output for the static libraries, they need to be explicitly installed from ‘glibc:static’, which allows Cargo to do its thing. Cargo itself should probably be fixed so that it no longer tries to link with these libraries, but until that time, the above work-around suffices.
bug#63238: issue linking to librt
Hello All, I believe I have stumbled on an issue with how the libraries in glibc are stored. If I run "ld -lrt" it reports "ld: cannot find -lrt: No such file or directory" Meanwhile, I can find librt with "ldconfig -p | grep librt": "librt.so.1 ... => /gnu/store/...". In order to get ld to find librt I need to take the following steps: - make a folder I can write to (not .~/guix-profile/lib) - symlink ~/.guix-profile/lib/librt.so.1 to /my-folder/librt.so - add the corresponding option to ld: "ld -lrt -L ~/lib" Then ld is able to find librt. I stumbled on this while trying to compile a rust project with "cargo build". Compiling any dependency that relied on libc failed on linking to librt. Feel free to let me know if there is some Guix facility I should be using instead. I am pretty new to this. I tried using cargo in a Guix shell but the same problem persisted.
