Kernel doesn't want to be found

[dmitrii.m...@gmail.com]

Hi!

On one of the clusters I use mpi version of Plumed.
I installed it with ./configure CC=/usr/bin/mpicc CXX=/usr/bin/mpicxx

When I try to run plumed, it seems to work fine, even though every time it warns me:

libibverbs: Warning: couldn't open config directory '/etc/libibverbs.d'.
libibverbs: Warning: couldn't open config directory '/etc/libibverbs.d'.

But when I try to run it with gromacs:

+++ Loading the PLUMED kernel runtime +++
+++ PLUMED_KERNEL="/home/nikolaev_d/QUEEN/lib/libplumedKernel.so" +++
+++ PLUMED kernel not found ! +++
+++ error message from dlopen(): libmpi_cxx.so.20: cannot open shared
object file: No such file or directory

However, libplumedKernel.so is located in this file, I defined it right. And this kernel is for the proper version of plumed.

Moreover, when I tried to use "static" mode, it just crashed on the step of gromacs installation...

Should I ask my system administrator to install some specific libraries?
Or may be I can solve this problem without "sudo" command?

Thank you in advance, Dmitrii.

The message is slightly misleading. The reported error means that even though /home/nikolaev_d/QUEEN/lib/libplumedKernel.so is present it cannot be opened since libmpi_cxx.so.20 is not in the LD_LIBRARY_PATH

Find that file and add its path to LD_LIBRARY_PATH
