[petsc-users] multiple definition of `main' with intel compilers

Configure attempts to automatically determine the language compatible libraries by running 'icc -v' and 'ifort -v' - and uses what it says. [this list can be different based on compiler options used]

And PETSc examples work fine - so its not clear why fcoremt_pic is causing issues with your app build.

There are some differences in your build vs examples - so that could be one reason. So its best to build PETSc and your app with the exact same compilers and options and see if that works.

Alternative is to specify to PETSc configure the compatibility libraries so that it doesn't try to figure this out. [and add extra un-needed libraries]

With Intel compilers - its likely the additional configure option is:

LIBS="-Bstatic -lifcore -Bdynamic"

If this works - configure won't run 'ifort -v' and grab fcoremt_pic etc..
