I've switched to merge-usr and since then I have issues with some packages that uses cmake. Basically when cmake modules uses find_library() to find libraries, errors like /usr/lib/gcc/x86_64-pc-linux-gnu/12/../../../../x86_64-pc-linux-gnu/bin/ld: /usr/lib/librhash.so: error adding symbols: file in wrong format happens. Apparently, find_library() is not able to detect properly that the right path should be /usr/lib64 and not /usr/lib When cmake module can use different strategies to find the libraries there are no problems. I tested this assumption by inserting a line like this one: set(CMAKE_FIND_LIBRARY_CUSTOM_LIB_SUFFIX "64") in a cmake module that showed the error, like FindCurses.cmake and the issue disappeared. Maybe the cmake.eclass could manage this situation, more or less similarly to what is done here: # See bug 689410 if [[ "${ARCH}" == riscv ]]; then echo 'set(CMAKE_FIND_LIBRARY_CUSTOM_LIB_SUFFIX '"${libdir#lib}"' CACHE STRING "library search suffix" FORCE)' >> "${common_config}" || die fi I'm trying to see if I can hack something but I'm not even sure if my diagnosis makes sense or not :) For

I made a quite dirty try, adding those lines to cmake.eclass and the compilation seems to go thru. I'm pretty sure this is not the right solution, but at least it seems to go in the right direction: # See bug 890967 if [[ "${ARCH}" == amd64 ]]; then if [[ "${ABI_X86}" == "64" ]]; then echo 'set(CMAKE_FIND_LIBRARY_CUSTOM_LIB_SUFFIX '"64"' CACHE STRING "library search suffix" FORCE)' >> "${common_config}" || die fi fi (or maybe any other suitable variable instead of ABI_X86)
