    opencl symbols


      Is there any way to get debug symbols for the AMDAPPSDK-3.0 libraries?


      I'm getting a persistenat segv from calling clGetPlatformIDs, very far down in the stack.  I have almost nothing to go on since the call is quite innocuous. I'd be happy to narrow it down, work around it whatever, but I have nothing to go on.


      Thanks in advance

          Please share below information for debugging the issue.

          1) Your setup details (OS, driver and SDK version etc.) and related environmental variables such as LD_LIBRARY_PATH.

          2) Are you observing similar segmentation fault if you run "clinfo"  or any sample from APP SDK?
