Compiler Mixed-Language Programs

When you compile with the -v(verbose) option, the Pascal driver brings in the runtime libraries for the main module.

However, when you compile a module that is not the main module, and which is written in a language different from the main module, you must explicitly bring in the runtime library on the command-line.

For example, you must use the compiler options –lpfcand –lpcwhen you compile a FORTRAN main routine that calls Pascal. The –lpfcoption links the common startup code for programs containing mixed Pascal and FORTRAN object libraries. The –lpcoption includes the Pascal object library, libpc.
