Re: [f2py] problem finding shared library: libsvml.so

Hello
When using the intel compilers, it is important to add in the basrc
the proper path
there is a batch in the bin directory to do so. Just add in your bashrc:

for example in my case:
source /opt/intel/composerxe-2011.0.084/bin/compilervars.sh intel64
in case of 64 bits and I think the option is ia32 for the alternative.
just check inside this file, it's written.

everything should work with this
Cheers
Xavier
