Hi, so yes I'm trying to install the source but after installing, it does
not seem to be able to locate the libraries.
mpirun gives the error
libopen-rte.so.0: cannot open shared object file: No such file or directory
Of course, I have seen this faq
But this is more than a little beyond me. The libraries seem to be
installed in usr/lib, (at least, that's where it locates the library in
question.) but I can't seem to get this to work by modifying
LD_LIBRARY_PATH, or using the --prefix switch. Obviously I am doing
something very wrong, never having bothered with editing paths before. (This
is why I use packages.)
