If so, it might not be possible to use the standard LD_PRELOAD approach on its own.

Instead, you must use that approach as normal while defining the MGD_LIBRARY_PATH environment variable as follows:

MGD_LIBRARY_PATH=/path/to/original/drivers/dir/

The /path/to/original/drivers/dir/ contains the pre-existing libGLESv2.so and libEGL.so files from the graphics driver installation.

When a graphics application runs, the Graphics Analyzer interceptor libraries are preloaded as normal. The interceptor libraries then dynamically load the original graphics libraries from the MGD_LIBRARY_PATH location as required.

See 6.1 Intercepting without using LD_PRELOAD for more information.
