Hey!
I'm trying to debug an opencl application on my Odroid Xu3 (With the Mali-T628 MP6), and when i try to use MGD, it completely crashes after the first opencl call giving me this error that the passthroughglesapi could not locate the handler function, but I'm not using any OpenGL in my project, just openCL... Does anyone have a clue on how I can solve this?
Thanks in advance,
Rui

Hi Rui,
The messages about not being able to find OpenGL functions in the pass through layer are just DEBUG messages not errors, so you can safely ignore those (typically the things that cannot be found are because the MGD supports the latest OpenGL ES spec and your driver may not).
The one about not being able to find 'clSetCommandQueueProperty' is more worrying since that's an OpenCL function that should be in every OpenCL library.
Can you tell us how you are loading the MGD interceptor? (e.g. LD_PRELOAD or using LD_LIBRARY_PATH).
And also the path to the OpenCL library on your device.
Thanks,
Jon.
Hi Jon
So, on my system OpenCL's library (libOpenCL.so) is in the /usr/lib folder.
As for the MGD interceptor, I'm using LD_PRELOAD=~/hard_float/libinterceptor.so followed by the programs and arguments.
I'm going to try and use the LD_LIBRARY_PATH and I'll edit this post with the results.
Hey Jon!
To complement my last post, i just found out that i have more than one libOpenCL.so, and I honestly don't know for sure which one is being used.
I have it in usr/lib; usr/local/lib and usr/lib/arm-linux-gnueabihf....
I tried setting LD_LIBRARY_PATH to include the path to libinterceptor.so (/home/ruialbuquerque/hard_float) and MGD
I wasan't abble to run my application with this method, but i did run a simple device query script and got this output:

Thanls for the atention,
Thanks for the info. Regarding ''clSetCommandQueueProperty', after a bit more digging that function has been deprecated and removed in later OpenCL versions so you can safely ignore that debug message.
What we think might be happening is that MGD is loading the incorrect version of libOpenCL. This might happen for example if you've set an rpath at link time to a specific OpenCL library, MGD doesn't know about that and tries to get libOpenCL just with a simple dlopen.
To try and fix it, if you can work out the version of libOpenCL.so that you app uses when running without MGD (either with ldd or strace). Once you have that, you can pass that location to MGD using the MGD_LIBRARY_PATH environment variable.
So LD_LIBRARY_PATH should point to the directory with MGD in it and MGD_LIBRARY_PATH should point to the directory with the libOpenCL.so your app wants in it.
If that fails or if you want more help, please ask.
The outputs of ldd and strace with and without loading MGD would be useful for us.
