Hi Nadir,

I looked into the configuration and source files and got the  
impression that it might take some time to fix this cleanly.

The build system has a compiler-dependent support of single and  
double trailing underscores in Fortran function names in libraries.   
Right now there seems to be no support  for a leading underscore.

A way that might fix your problem (although not very elegantly) could  
be to

1.) replace in mtl2lapack.h

#define MTL_FCALL(x) x##_

with

#define MTL_FCALL(x) _##x##_

2.) replace in lapack_interface.h

   void dgeev_(const char& jobvl, const char& jobvr,

with

   void _dgeev_(const char& jobvl, const char& jobvr,

I hope this works.

Best,
Peter
