I made the mistake of upgrading from Precise Pangolin to Quantal Quetzal thinking the drivers/opencl would work without issue.
I just found these links which might be helpful for others:
I have an opencl issue:
3.5.0-17-generic #28-Ubuntu SMP Tue Oct 9 19:31:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
display: screen: 0
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: AMD Radeon HD 7900 Series
OpenGL version string: 4.2.11903 Compatibility Profile Context
Then, when I do:
I get the following error:
SDKCommon.cpp: In member function ‘std::string streamsdk::SDKCommon::getPath()’:
SDKCommon.cpp:41:67: error: ‘readlink’ was not declared in this scope
make: *** [build/debug/x86_64//SDKCommon.o] Error 1
That fixes it and everything builds. The fix is related to changes in the new gcc 4.7 found in Quantal Quetzal(ubuntu 12.10).
