plumed error rerated to its library "libplumedKernel.so"

[kimu handexyin]

Dear all,

I executed these commands and installed plumed successfully according to this screenshot;

 $./configure --prefix /misc/home/ikuma/plumed-2.6.1

 $make 

 $make install

But when I try run plumed, it fails as the bellow;

$ plumed

plumed : error while loading shared libraries: libplumedKernel.so: cannot open sheared object files: No such file or directory

I followed instructions on the attached screenshot, meaning;

 1. add /misc/home/ikuma/plumed-2.6.1/bin to $PATH

 2. add /misc/home/ikuma/plumed-2.6.1/lib to $PATH

 3. set PLUMED_KERNEL=/misc/home/ikuma/plumed-2.6.1/lib/libplumedKernel.so as an environmental variable

 4. save these settings in my .bashrc and activate it using $ source

But the same error message happens.

Does anyone know what I should do?

Best Regards,

kimu

You should add /misc/home/ikuma/plumed-2.6.1/lib to LD_LIBRARY_PATH I think

Dear Giovanni,

Thank you for your advise.

I added /misc/home/ikuma/plumed-2.6.1/lib to LD_LIBRARY_PATH, and the error message doesn`t happen now, but a new error appears;

$ plumed

plumed : error while loading shared libraries: libmpi_cxx.so.1: cannot open sheared object files: No such file or directory

Do anyone know what I should do next ? Do I have to find the directory where "libmpi_cxx.so.1" is stored? 

Best Regards, 

kimu

Yes, you have to find where the library is and add that path to LD_LIBRARY_PATH.

The standard way (at least in my institute) to manage software installed in non canonical paths is to write modulefiles that allow you to add specific paths to PATH and LD_LIBRARY_PATH (and also to INCLUDE and LIBRARY_PATH, if they are library that should be used in other programs) using commands such as `module load openmpi`.
