[GAP Forum] Compiling GAP for Use in C Program

[Wolstenholme, Robert]

I want to compile some of my GAP functions into static libraries for use in a C program. I have compiled them using gac -c on Ubuntu but I 'm not sure how to now call these functions in my C program. I tried a few things but whenever I tried to link and create a binary I got an error.

For example I initially tried a "Hello World" example with

HelloWorld.g =
-------------------------------------------------------------+
PrintEO := function ( n )  Print( "Hello World" ); end; |
-------------------------------------------------------------+

HelloWorldMain.c =
-----------------------+
#include <stdio.h>  |
                             |
'''?void PrintEO()?'''' |
int main()               |
{                            |
    '''?PrintEO()?'''     |
    return 0;            |
}                           |
-----------------------+
Where I don't know what to put for the '''?PrintEO()?'''. I analysed the created source code using gac -C but it still wasn't clear to me. How would I go about getting this to work?
