Recently I had to mix two large models written in C and Fortran (95 standard) to build a single monolithic program. In theory cross compilation is easy -- in practice its far from it. Your run off the mill 'hello world' implemented in C and called from Fortran (or vice versa) is one thing, but marrying off two large programs (numerous code files in each) written in two languages is a whole different story. Following is an account of my experience:
