Hi Andreas,
Building from git on windows 64 bit with the tss issue commented out I
get an executable that runs my own little codes but fails lots of test
cases. It may be a problem of this tss, but I am lost on how to fix it
properly. I have the impression that the tss patch is not really the
issue for these failures, but any suggestion is welcome.
Thanks
Jon
test_wrapper.py:
================
segfaults early on. Running the test using "py.test --capture=no" helped
to find the problem... it boils down to an intel issue (SDK 1.5), I get
the same crash from a C program:
ctx=pyopencl.create_some_context()
ctx.get_info( pyopencl.context_info.PROPERTIES )
**CRASH**, gdb output is attached in case it makes sense to you:
Choose platform:
[0] <pyopencl.Platform 'NVIDIA CUDA' at 0x482afd0>
[1] <pyopencl.Platform 'Intel(R) OpenCL' at 0x3599700>
Choice [0]:1
Set the environment variable PYOPENCL_CTX='1' to avoid being asked again.
