### Interfacing with Other Languages

The standardized GNU compiler back-end makes it relatively easy to share libraries between GNU Pascal and other GNU compilers. On Unix-like platforms (not on Dos-like platforms), the GNU compiler back-end usually complies to the standards defined for that system, so communication with other compilers should be easy, too.

In this chapter we discuss how to import libraries written in other languages, and how to import libraries written in GNU Pascal from other languages. While the examples will specialize to compatibility to GNU C, generalization is straightforward if you are familiar with the other language in question.
