Segmentation default caused by DFTI function

TravelerPhys — Thu, 21 Sep 2023 16:32:55 GMT

I wrote a c language code in which DFTI is used, and it is attached. The filename is "test.c"

The compilation command line is " icx test.c -g -qmkl=parallel -lgsl -lgslcblas -lmkl_core -lmkl_intel_lp64 -lmkl_intel_thread -liomp5 -lpthread -qopenmp -lm -o test ".

I then used gdb: " gdb ./test ".

It can be seen that after DftiCommitDescriptor(fft_handle) was called, the address that the pointer "uv" pointed to cannot be accessed.

I would be very grateful if this problem could be solved.

Hi,

Thank you for posting in Intel Communities..

Please use below command line to compile the attached test code.

" icx test.c -g -qmkl=parallel -lmkl_core -lmkl_intel_lp64 -lmkl_intel_thread -liomp5 -lpthread -qopenmp -lm -o test ".

We have removed "-lgsl -lgslcblas " flags from command line as we could see that your code is not using any GSL specific implementations. We could see the code is working fine without any issues after this change.
