[question] Running CCTag with GDB/Valgrind
anand97 opened this issue · 1 comments
I am trying to use CCTag as a third party library with Cuda acceleration as described in the docs, and want to debug my application w/ cctag, which seems to be crashing with a Segfault. I tried to run the application with gdb, and later with cuda-gdb, but both seem to segfault before processing the first image, at Line 76 in src/cctag/cuda/tag_threads.cu. The line seems to be capturing a lock on a mutex in the TagSemaphore class, so its not clear what is causing the segfault.
I'm happy to provide additional information a necessary, I would appreciate any help towards enabling debugging with the cctag library or suggestion to what this segfault could be about. Thanks!
