    Problem debugging OpenGL applications on Fedora 18

    muogoro

      I'm trying (without success) to use CodeXL to debug my OpenGL applications. I'm working on a Fedora 18 64bit installation, using 14.1 beta driver, APP SDK 2.9 and CodeXL 1.3. The driver is installed using the official installer. Outside the CodeXL debugging environment, everything works with no problem (even context sharing with OpenCL). Using the aforementioned debugging environment, I cannot manage to initialize a valid OpenGL context with version greater than 1.1. For instance, the provided teapot example works fine if launched standalone, but when run inside CodeXL it only shows an empty black window.

      Looking at the log file, it seems that the AMDTOSWrappers module does not manage to retrieve the functions pointer for a lot of OpenGL API functions:

      For further information, I've attached the complete log files.

       

      Thanks for your help,
