(Define a macro to) facilitate OpenGL command debugging?

Question

Sometimes it takes a long time of inserting conditional prints and checks to glGetError() to narrow down using a form of binary search where the first function call

Answer 1

BuGLe sounds like it will do what you want:

• Dump a textual log of all GL calls made.
• Take a screenshot or capture a video.
• Call glGetError after each call to check for errors, and wrap glGetError so that this checking is transparent to your program.
• Capture and display statistics (such as frame rate)
• Force a wireframe mode
• Recover a backtrace from segmentation faults inside the driver, even if the driver is compiled without symbols.
