When trying to use cdparanoia, I noticed the following: $ ldd `which cdparanoia`
linux-vdso.so.1 => (0x00007fff1e9dd000) libcdda_interface.so.0 => not found libcdda_paranoia.so.0 => not found libm.so.6 => /nix/store/53afsq4c7r10hn77h3iyyavy2bs02403-glibc-2.17/lib/libm.so.6 (0x00007fb37355b000) librt.so.1 => /nix/store/53afsq4c7r10hn77h3iyyavy2bs02403-glibc-2.17/lib/librt.so.1 (0x00007fb373353000) libc.so.6 => /nix/store/53afsq4c7r10hn77h3iyyavy2bs02403-glibc-2.17/lib/libc.so.6 (0x00007fb372fa5000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fb372d89000) /nix/store/53afsq4c7r10hn77h3iyyavy2bs02403-glibc-2.17/lib/ld-linux-x86-64.so.2 => /lib64/ld-linux-x86-64.so.2 (0x00007fb373877000) The two missing libraries are part of the package itself; apparently, they do not get encoded into the rpath. Could this be handled somehow by the build system? Should it be done in the package definition? Or should I set an LD_LIBRARY_PATH? Andreas
