Question

I have several object files (.o) ,without source code, for a vxWorks project.

How can I test if they are OS independent or not?

I try to use them for a Linux project.
They should include openGL stuff.

edit:

I have a Graphic board with a S3 on it.
There is a driver available for it, but just for vxWorks.
I found a startup script for vxWorks. In this several Objekt files will be loaded.

e.g this

ld 1,0,"lib/libGL.o"        
ld 1,0,"lib/libGLU.o"       

And I think they are independent from the OS.But I’m not sure.
Because I try to use this board with Linux.

Link them against a main() function. If you get no errors, then they don’t use OS specific functions.

[EDIT] Object files are linked, not included. You need to write a main() function which calls code in the .o files (check the OpenGL documentation for the names).

Now you can compile this with:

 cc -c -o main.o main.c
 cc -o main main.o lib/libGL.o lib/libGLU.o
