Add to C program :
#include <Cg/cg.h> /* To include the core Cg runtime API into your program */ #include <Cg/cgGL.h> /* to include the OpenGL-specific Cg runtime API */
Using the Java native interface (JNI), Java applications can call C libraries.
To mix Perl and C, we can use XS. XS is an interface description file format used to create an extension interface between Perl and C code (or a C library) which one wishes to use with Perl.
The basic procedure is very simple. We can create the necessary subdirectory structure by running "h2xs" application (e.g. "h2xs -A -n Modulename"). This will create - among others - a Makefile.PL, a .pm Perl module and a .xs XSUB file in the subdirectory tree. We can edit the .xs file by adding our code to that, let's say:
void hello() CODE: printf("Hello, world!\n");
and we can successfully use our new command at Perl side, after running a "perl Makefile.PL" and "make".
Here can be found some details about extending Python with moduls written in C. You might read about Cython and Pyrex as well, that makes easier to create modules in C, translating a Python-like code into C.
