Public bug reported:
Recently I built a library with Intel MKL as a dependency (libmkl-dev
package). Trying to run an application threw me an error message:
"undefined symbol: omp_get_num_procs". The problem turned up to be old
and known (https://software.intel.com/en-us/forums/intel-system-
studio/topic/611682) -- missing libiomp5.so.
Examining dependencies of libmkl-dev leads to chain: libmkl-dev ->
libmkl-rt -> libomp5 which must contain libiomp5.so. The last one
depends only on libc6.
But package libomp5 only contains documentation, not the library:
$ apt-file show libomp5
libomp5: /usr/lib/x86_64-linux-gnu/libomp.so.5
libomp5: /usr/share/doc/libomp5/changelog.Debian.gz
libomp5: /usr/share/doc/libomp5/copyright
libomp5: /usr/share/lintian/overrides/libomp5
All libraries are packed into libomp-dev:
$ apt-file show libomp-dev
libomp-dev: /usr/include/omp.h
libomp-dev: /usr/include/ompt.h
libomp-dev: /usr/lib/x86_64-linux-gnu/libgomp.so
libomp-dev: /usr/lib/x86_64-linux-gnu/libiomp5.so
libomp-dev: /usr/lib/x86_64-linux-gnu/libomp.so
libomp-dev: /usr/lib/x86_64-linux-gnu/libomptarget.so
libomp-dev: /usr/share/doc/libomp-dev/changelog.Debian.gz
libomp-dev: /usr/share/doc/libomp-dev/copyright
