I have installed openmpi-bin and openmpi-common, and I get the following error when I run either mpirun or mpiexec:

mpirun: error while loading shared libraries: libopen-rte.so.12

As I checked, this library should be a part of the openmpi-bin (or common), but no matter how many times I try to reinstall it i get the same error.

Also no libraries like lib*-rte.* can be found at /usr/lib, and i cant find anything similar in other lib folders neither.

What should I do?

  • Did you install openmpi-bin and openmpi-common fromthe standard repositories? What does apt-cache policy libopenmpi1.10 say? – steeldriver Jan 19 '18 at 13:09
  • @steeldriver $ apt-cache policy libopenmpi1.10 libopenmpi1.10: Installed: 1.10.2-8ubuntu1 Candidate: 1.10.2-8ubuntu1 Version table: *** 1.10.2-8ubuntu1 500 500 http://archive.ubuntu.com/ubuntu xenial/universe amd64 Packages 100 /var/lib/dpkg/status – Gábor Erdős Jan 19 '18 at 13:43

You may just need to run this command to link the appropriate libraries:

sudo ldconfig

    what does it do? – Pierre.Vriens Dec 11 '18 at 11:32

    ldconfig creates the necessary links and cache to the most recent shared libraries found in the directories specified on the command line, in the file /etc/ld.so.conf, and in the trusted directories (/lib and /usr/lib). look here for many informations https://www.systutorials.com/docs/linux/man/8-ldconfig – Compiii Dec 11 '18 at 20:24

    @Compiii Could you please [edit] your answer and provide the above comment there? – Fabby Dec 12 '18 at 00:46

My system says that this library comes from the package libopenmpi1.10. So you will need to install this.

$ find /usr/lib -name *libopen-rte*
/usr/lib/libopen-rte.so
/usr/lib/openmpi/lib/libopen-rte.so
/usr/lib/openmpi/lib/libopen-rte.so.12.0.2
/usr/lib/libopen-rte.so.12.0.2
/usr/lib/libopen-rte.so.12
$ dpkg -S /usr/lib/libopen-rte.so.12
libopenmpi1.10: /usr/lib/libopen-rte.so.12
