I would like to install openmpi from repository and need to use it with GCC. The problem is I have installed intel libraries too and it causes problems like this:

mpicc.openmpi --version
mpicc.openmpi: error while loading shared libraries: libimf.so: cannot open shared object file: No such file or directory

Version of my GCC is:

gcc (Ubuntu 5.4.0-6ubuntu1~16.04.2) 5.4.0 20160609

I'm trying to install openmpi with following command:

sudo aptitude install openmpi-bin libopenmpi-dev

So, how can I install OpenMPI from repositories in the way which would ignore intel libraries and use only GCC?

I've installed intel package Intel® Parallel Studio XE | Intel® Software manually (i.e., ./install_gui.sh).

EDIT 2

I tried to reinstall OpenMPI with

sudo apt-get install --reinstall openmpi-bin libopenmpi-dev

and with

sudo apt-get purge openmpi-bin libopenmpi-dev
sudo apt-get install openmpi-bin libopenmpi-dev

but none of them had the desired effect, library still links against intel libraries.

Intel libraries are located in /opt/intel.

• As it seems, the Intel mpicc.openmpi overwrote the official one from repository or one of its linked libraries.

  Here is my output of a official install from repository:

   ~$ dpkg -S /usr/bin/mpicc.openmpi libopenmpi-dev: /usr/bin/mpicc.openmpi ~$ ldd /usr/bin/mpicc.openmpi linux-vdso.so.1 => (0x00007ffd785f4000) libopen-pal.so.13 => /usr/lib/libopen-pal.so.13 (0x00007ff1d848d000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007ff1d8270000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007ff1d7ea6000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007ff1d7ca2000) librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007ff1d7a9a000) libutil.so.1 => /lib/x86_64-linux-gnu/libutil.so.1 (0x00007ff1d7896000) libhwloc.so.5 => /usr/lib/x86_64-linux-gnu/libhwloc.so.5 (0x00007ff1d765c000) /lib64/ld-linux-x86-64.so.2 (0x000056499326f000) libnuma.so.1 => /usr/lib/x86_64-linux-gnu/libnuma.so.1 (0x00007ff1d7450000) libltdl.so.7 => /usr/lib/x86_64-linux-gnu/libltdl.so.7 (0x00007ff1d7246000)

  It does not relay on those missing libraries.

• To fix it you can reinstall libopenmpi:

   sudo apt-get install --reinstall openmpi-bin libopenmpi-dev

• Also notice /usr/local/lib/libopen-pal.so.13. It's in /usr/local/lib/ folder so it has higher priority then official one in /usr/lib/, compatibility may be broken.

  Check for all sub-versions using

   ls -l /usr/local/lib/libopen-pal.so.13*

  then rename them, example

   sudo mv /usr/local/lib/libopen-pal.so.13 /usr/local/lib/libopen-pal.so.13.backup
