I installed cuda 5 in my Ubuntu 12.10 and it is working well, I can compile and debug through cuda-gdb in terminal as well. I'm trying to use nsight, it compiles and executes my code with no issues, but when I try to debug I got the following error
Error in final launch sequence
Failed to execute MI command:
-gdb-set cuda api_failures ignore
Error message from debugger back end:
Undefined set cuda command: "api_failures ignore". Try "help set cuda".
Undefined set cuda command: "api_failures ignore". Try "help set cuda".
I'm using ubuntu 12.10 64 bits and launching cuda executables and nsight with optirun (bumblebee) because I have a GTX 675M (optimus). I installed cuda-gdb throught apt-get, I got version 4.2:
frederico@zeus:~/Dropbox/coisas/projetos/delta_cuda$ cuda-gdb --version
NVIDIA (R) CUDA Debugger
4.2 release
Portions Copyright (C) 2007-2012 NVIDIA Corporation
GNU gdb (GDB) 7.2
I think this is not a problem since I can use it alone (without nsight). I changed nsight to launch cuda-gdb with optirun as well, keep receiving the same error.
The problem was the version of cuda-gdb, I had to use cuda-gdb version 5. It comes with the toolkit version 5, just did a symbolic lick to /usr/bin and it's working.
