我正在使用 Visual Studio 2008 运行 Windows 7 64 位。我安装了 CUDA 驱动程序和 SDK。SDK 附带了很多示例，包括已编译的可执行文件和源代码。编译后的可执行文件运行良好。当我打开 vc90 解决方案并在 Win32 配置中构建时，我收到此错误：

Error   1   fatal error LNK1181: cannot open input file '.\Release\bandwidthTest.cu.obj'    bandwidthTest   bandwidthTest

构建日志：

如果我尝试在 x64 中编译，它根本不会构建，只是跳过项目

我是 C++ 新手，从事 C# 已经有一段时间了。我确定我缺少一些小东西，但是您可以提供的任何线索将不胜感激。

检查您是否安装了 x64 编译器。然后将项目类型更改为 x64。我在尝试用 64 位 win7 编译 32 位 cuda 程序时遇到了同样的问题。

还要确保您已将 64 位库添加到搜索路径中。

您正在关注错误的错误消息。

.obj 文件不存在，因为 nvcc 编译步骤失败。

nvcc fatal   : Visual Studio configuration file '(null)' could not be found for installation at 'c:/Program Files (x86)/Microsoft Visual Studio 9.0/VC/bin/../..'

You need to make sure that all the tools match. So if you have the 64-bit Visual Studio compiler installed then you should install the 64-bit version of the CUDA toolkit.

If you only have the 32-bit Visual Studio compiler, then you should be able to install the 32-bit CUDA toolkit. Ideally you would install all the 64-bit tools. Then you will be able to build both the 64-bit and 32-bit (cross-compile) examples.
