Link Pardiso solver with gfortran

[Arjen Markus]

Hello Behnam,

please understand that there is NO relationship between the name of
the source file and the name of the subroutine(s) it contains. It is
merely a convention to make them the same. It is the subroutine or
function statement that defines the name as it is to be used in
Fortran code.

The underscore you see in the error messages is added by the compiler
as a simple decoration. It defines the name of the program unit as
seen by the linker. In particular: all lowercase (Fortran is
case-insensitive and some but not all compilers translate the names to
lowercase) and an underscore appended to avoid clashes with system
routines or C routines.

So, no, you do not want to rename the files.

What you need to do is run the "nm" command for the BLAS and LAPACK
libraries that you use in the link command. That should you what the
actual names are in these libraries. (Use the man pages to read about
this command and its output)

Regards,

Arjen
