I have a test application that uses OpenGL to draw in glContext Viewport. It used to compile correctly using GCC in the shell on ABIv1 with -lgl -lglu -lglut but now on ABIv11 the compilers says there are unknown symbols such as glPopAttrib which is part of OpenGL and for AROS I suppose it's Mesa.

What is the correct includes for the test application and the GCC lib links (-l + ?) to get it to compile?

I'll post the source code for my test app later today.

Can you post the linker command like you are using and the error you are getting?

For example:
gcc 3dwireframe.c -o 3dwireframe -lgl -lglu -lglut

The error is "unknown symbols" and it's a list of about 10 items all starting with gl which seem to be OpenGL commands. The first item in the list is glPopAttrib.

-lgl has to be after -lglut I think

just do:

-lgl -lglu -lglut -lgl

Godsend; just compiling new Skia and I needed GL as well.

@coffeecat

Is it the same setup for compiling Skia with GL ? What are your GL include statements?

Success!

Thank you @deadwood

I used -lglu -lglut -lgl and that compiled correctly on 64bit.

My includes:
<GL/gl.h>
<GL/glu.h>
<GL/glut.h>

Now I have GL wireframes!

Great Congratz
