OpenGL Debugging Tips:
- If you suspect an error in your OpenGL code, try using the glGetError() command to find the location of the error, then gluErrorString() to parse the error message.
- There is a web page on common OpenGL mistakes.
- For debugging under Linux, the command line debugger gdb and the GUI wrapper around it ddd are among the most popular debugging tools, both of which allow tracing through C++ code step by step and displaying the content of variables.
- The Curses debugger is a powerful text mode extension of gdb: CGDB
For GLSL Shader Development:
- If your shader code builds but won't use the shaders, and you are using Linux and a laptop with hybrid graphics systems, try Ironhide.
