Hi Charles,
I have another curious situation. I have installed pocl 0.14 on a
ubuntu 14.04 system. I can install and run clinfo without any
problems. However, when I compile and run my context.cpp file
(https://github.com/cdeterman/gpuR/blob/develop/src/context.cpp) and try
to run the initContexts function I keep getting a -1001 error for the
get_platforms call.
Any idea why this script would be failing to find the platforms whereas
even a basic query file like this
(https://github.com/cdeterman/pocl_test/blob/master/clDeviceQuery.cpp)
can be compiled simply with
g++ -o clDeviceQuery clDeviceQuery.cpp -lOpenCL
and run without a problem.
whenever I've seen problems with querying platform information it was
due to a problem with the OpenCL environment: Either the GPU driver was
not correctly installed (unlikely in your case) or the wrong
libOpenCL.so was picked up (more likely here). Can you verify with ldd
that the correct libOpenCL.so is picked up? clDeviceQuery and gpuR
should pick up the same libOpenCL.so.
Best regards,
Karli
