[mpich-discuss] error while loading shared libraries: libsvml.so

[Martin Siegert]

Hi Angel,

you may want to add the line

-Wl,-rpath,/opt/intel/cce/9.1.042/lib

to you icc.cfg file (and a similar line to ifort.cfg, icpc.cfg)
and then recompile. The problem appears to be that the library is
not found at runtime.

Cheers,
Martin
