Shared libraries for third-party binaries

Hummel-2 has a minimal operating system image, which in turn contains only a minimal set of shared libraries. Therefore it happens that third-party software is missing some shared libraries. On Hummel-2 many shared libraries are provided by pkgsrc Modules, but Hummel-2 Modules do not set $LD_LIBRARY_PATH.

If a shared library is missing it is likely to be available in a pkgsrc Module and can be used by setting $LD_LIBRARY_PATH:

   module avail env
   ...
   module switch env env/yyyyQq-compiler-MPI
  • set $LD_LIBRARY_PATH to $LIBRARY_PATH before calling the third-party binary
   LD_LIBRARY_PATH=$LIBRARY_PATH third-party-binary
  • if there are still libraries missing try an older pkgsrc Module
