编译 CUDA 示例出现构建错误
我运行的是 Windows 7 64 位，带有 Visual Studio 2008。我安装了 CUDA 驱动程序和 SDK。 SDK 附带了很多示例，包括编译的可执行文件和源代码。编译后的可执行文件运行得非常好。当我打开 vc90 解决方案并在 Win32 配置中构建时，出现此错误：
Error 1 fatal error LNK1181: cannot open input file '.\Release\bandwidthTest.cu.obj' bandwidthTest bandwidthTest

如果我尝试在 x64 中编译，它根本不会构建，只是跳过该项目

我是 C++ 新手，一直在做 C#一阵子。我确信我缺少一些小东西，但是您可以提供的任何线索将不胜感激。
I am running Windows 7 64bit, with Visual Studio 2008. I installed the CUDA drivers and SDK. The SDK comes with quite a few examples including compiled executables and source code. The compiled executables run wonderfully. When I open the vc90 solutions and go to build in Win32 configuration I get this error:
Error 1 fatal error LNK1181: cannot open input file '.\Release\bandwidthTest.cu.obj' bandwidthTest bandwidthTest

If I attempt to compile in x64 it doesn't build at all and just skips the project

I am new to C++, having been doing C# for a while. I'm certain there is something small that I am missing, but any clues you could provide would be appreciated.

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。
另请确保您已将 64 位库添加到搜索路径中。
Check if you have x64 compiler installed. Then change project type to x64. I had the same problem when trying to compile 32bit cuda program with 64bit win7.
Also make sure you have added 64bit libs and includes to the search path.
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。
You're focusing on the wrong error message.
The .obj file doesn't exist because the nvcc compile step failed.
您需要确保所有工具都匹配。因此，如果您安装了 64 位 Visual Studio 编译器，那么您应该安装 64 位版本的 CUDA 工具包。
如果您只有 32 位 Visual Studio 编译器，那么您应该能够安装 32 位 CUDA 工具包。理想情况下，您应该安装所有 64 位工具。然后您将能够构建 64 位和 32 位（交叉编译）示例。
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.
