Ubuntu 12.10 64 ビットに cuda 5 をインストールしました。私は GTX 675M を持っているので、bumblebee を使用して cuda デバイスでアプリを実行しています。バンブルビー(optirun)でnsightを実行しています:
frederico@zeus:~$ optirun /usr/local/cuda/libnsight/nsight
そして、問題なく動作し、アプリケーションをコンパイルして実行できます。問題は、nsight で cuda-gdb を使用しようとすると、デバッグ ボタンをクリックすると次のエラーが発生することです。
No source available for "main() at 0x403c6f"
しかし、コンソールで cuda-gdb を使用しようとすると、動作します:
frederico@zeus:~/Dropbox/coisas/projetos/delta_cuda$ optirun cuda-gdb bin/linux/release/gpu_md5
