Erhm, why are you linking against libf2c? I assume you're using G77 or GFortran. In either case, you should use the appropriate library for that compiler: libg2c for G77 and libgfortran (possibly also libgfortranbegin) for GFortran.

If you use Autotools for your build system, then "configure" will figure these things out automatically for you. A quick search on ROOTTalk will give you pointers to examples.

If you rolled your own build system - which I certainly would not recommend - then you need to make proper checks yourself - see for example the ROOT build system.

Note, that you should not link against an archive (aka static library - normally ending in ".a") when building libraries (aka shared library - normally containing ".so" and ending in a version number), since the archive does not contain position independent code (PIC). If you're building an executable via archives, then you need to be a bit careful with the link order (most derived first).

Yours,
