Error loading shared libraries: libmpc



  • I have an existing project with C++ files. I opened that project on Qt and went to Debug->Start debugging, but I get an error message
    /opt/apps/ossw/applications/gcc/gcc-4.6/sl6/libexec/gcc/x86_64-unknown-linux-gnu/4.6.3/cc1plus:-1: error: error while loading shared libraries: libmpc.so.3: cannot open shared object file: No such file or directory

    I don't understand why I'm getting this because I never got this error when I compiled before using CMakeLists and make on Linux

    When I tried to search for that file, I see a ton of directories, but they all also say Permission denied on the command prompt

    What can I do to resolve this?

    Hi and welcome to devnet,

    Do you have that file there ? The rights to access it ? Is it pointing to something valid ?

    Permission denied can have several sources, either your user just don't have the rights to access these folders (which is strange) or you may be trying to access a mounted device that's not there anymore.
