c++ - CUDA-GDB 在 C/C++ 中查看变量

Question

我已经安装了 NVIDIA 提供的最新版本的 CUDA 驱动程序

mmiller@host:~/NVIDIA_CUDA-7.5_Samples$ nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2015 NVIDIA Corporation
Built on Tue_Aug_11_14:27:32_CDT_2015
Cuda compilation tools, release 7.5, V7.5.17

但是当我调试程序时，我收到一条关于 python 的错误消息。

mmiller@csit-crackin:~$ cuda-gdb hello.out

我的程序是一个非常简单的程序，我读到它可能是处理 python 和 gdb 的错误，但我不确定如何使用 Ubuntu 和 Nvidia 的最新软件修复错误。关于如何解决这个问题有什么建议吗？

Answer 1

看来 Ubuntu 不会更新路径以包含最新版本的 nvcc 和 cuda-gdb。您必须手动更新路径(或更改符号链接(symbolic link))才能引用这些库的正确版本。
