The problem is that I personally do not want to program C.
I need to adjust a program that is written in C by a colleague that left the company.
With minimum effort, if possible.
The program that is being executed actually only needs to return 0, 1 or -1, so that is quite simple.
If I could program C, I would not use a system command at all.
It is basically a C program calling a Perl program, which seems stupid.
Anyway, it is working now and serves its purpose.
Perhaps later I will have a go at it and integrate the Perl program into the C program.

GL_INVALID_OPERATION is generated if shader is not a shader object.
GL_INVALID_OPERATION is generated if shader is not attached to program.
