我正在为一个 g++ 链接项目开发一个 nvcc 编译的静态库。如何在最终可执行文件上使用 cuda-gdb？我得到的只是"程序正常退出"，没有任何 printf 输出或任何东西。
在编译静态库时，NVCC 肯定会被赋予 -g -G 参数。
这是我的命令行缓冲区：

这是在没有调试的情况下通常会发生的情况：

- 应在发出运行命令之前设置断点。
- 您的应用程序是否执行正确的错误检查？请注意，cuda-gdb 可能会"隐藏"用于呈现操作系统图形界面的 GPU。例如，如果您有一个 GPU 系统并在窗口环境（如 GTK 或 KDE）中从 cuda-gdb 运行 CUDA 应用程序，您的应用程序可能会失败，因为不会检测到 GPU。
