Hi, I can't get cuda-gdb to stop at breakpoint. Namely, I get

I'm using Debian jessie/sid amd64. I have tried both 319.60 and 325.15 drivers (and many other versions previously), and CUDA toolkit 5.0.35 and 5.5.22. No change on this front. I'm using PyCUDA 2013.1.1. Any ideas? Regards, Vedran _______________________________________________ PyCUDA mailing list PyCUDA@tiker.net http://lists.tiker.net/listinfo/pycuda
