解决在QT中编写CUDA程序出现nvcc fatal : Could not set up the environment for Microsoft Visual Studio using的问题

问题详情

在QT编写CUDA代码，在已经配好.pro文件中的代码，并且CUDA安装没有问题，还可以在VS2017中正常运行CUDA程序时，一开始debug的时候我遇到了以下问题： Could not set up the environment for Microsoft Visual Studio using，

nvcc fatal   : Could not set up the environment for Microsoft Visual Studio using 'C:/Program Files (x86)
				/Microsoft Visual Studio/2017/Professional/VC/Tools/MSVC/14.16.27023/bin/HostX64/x64/../../../../../../../VC/Auxiliary/Build/vcvars64.bat'

我在网上找了好久的解决办法，国外的社区还有国内的社区，都没有详细可靠的解决方案，总结下来他们的方法大致包括检查系统的环境变量，CUDA的路径不能有空格，nvcc的输入太长等，但这些都不能解决这个问题。

这确实花费了我很长的时间还有精力，因此我发布出我的解决方案，后面也有详细的解决过程，希望我的分享可以帮助到你。

解决方案

下面我会给出解决方案，想直接解决问题的看完这一部分就行了，想了解我解决问题的过程的可以看第三部分。
下面是解决方案：找到报错中的文件路径，可以参考我的路径：
C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Auxiliary\Build
找到相应的文件，用记事本打开vcvarsall.bat，复制其中的代码到vcvars64.bat，最终vcvars64.bat中的内容为：

这样问题就解决了，可以顺利Debug

解决过程

（1）在一开始debug的时候我遇到了以下问题： Could not set up the environment for Microsoft Visual Studio using

nvcc fatal   : Could not set up the environment for Microsoft Visual Studio using 'C:/Program Files (x86)/Microsoft Visual Studio/2017/Professional/VC/Tools/MSVC/14.16.27023/bin/HostX64/x64/../../../../../../../VC/Auxiliary/Build/vcvars64.bat'

我在网上找了好久的解决办法，国外的社区还有国内的社区，都没有详细可靠的解决方案，总结下来大致的方法包括检查系统的环境变量，CUDA的路径不能有空格，nvcc的输入太长等，但这些都不能解决这个问题。

（2）在尝试了很长时间之后，我还是决定根据报错信息入手，我找到了出现问题的vcvars64.bat这个文件，默认路径在：
C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Auxiliary\Build
并用记事本打开，其中的内容如下，只有这一行：

@call "%~dp0vcvarsall.bat" x64 %*

（3）之后我在QT的工具->选项->Kits->编译器，发现QT中的编译器使用都是与上述vcvars64.bat同一路径下的vcvarsall.bat文件。
CUDA配置环境（三）：nvcc fatal : Could not set up the environment for Microsoft Visual Studio using 已解决
（4）因此我首先想要改变我的.pro文件调用vcvars文件的代码，有关的代码如下：

SYSTEM_TYPE = 64

改变等号右边的值，可以改变调试时使用的vavars文件的后缀，但是他只能接收数字输入，所以也无法使其调用vcvarsall.bat，因此只能另辟蹊径，考虑将vcvarsall.bat的内容复制到vcvars64.bat，达到调用vcvarsall.bat的效果。

（5）最终解决方案，用记事本打开vcvarsall.bat，复制其中的代码到vcvars64.bat文章来源地址https://www.toymoban.com/news/detail-438846.html
