在Visual Studio C ++项目中使用尖峰 [英] Using cusp in a Visual Studio C++ project
问题描述
我在VS2012 Ultimate上使用cusp v.0.4.0，cuda V5.5。我使用新的项目向导创建了一个CUDA项目，并将cusp路径添加到它的项目属性\VC ++ Directories \Include目录。我在VS2012生成的 *。cu 文件中编写了我的代码，项目已成功编译并构建，但我遇到了 R6010 错误。我通过将项目属性\CUDA C / C ++ \Device\Code生成的默认值从 compute_10，sm_10 更改为 compute_30，sm_30 ，这是我的sm版本。一切运行良好。
I'm using cusp v.0.4.0, cuda V5.5 on VS2012 Ultimate. I created a CUDA project using the new project wizard and added the cusp path to it's project properties\VC++ Directories\Include Directories. I wrote my code in the *.cu file generated by VS2012, the project compiled and built successfully but I got R6010 error on execution. I solved this issue by changing the default value of project properties\CUDA C/C++\Device\Code Generation from compute_10,sm_10 to compute_30,sm_30, which is my sm version. Everything worked well.
现在我想在C ++项目中使用相同的代码。当我将它添加到一个新的C ++项目中，并且我将cusp路径添加到 VC ++ Include Directories 时，项目生成失败，并且在多个文件中出现了大量的语法错误：
Now I want to use the same code in a C++ project. When I added it to a new C++ project and I added the cusp path to VC++ Include Directories, the project build failed with numerous syntax errors in several files:
错误5错误C2144：语法错误：'void'应该在';'前面c：\users\administrator\downloads\android\cusplibrary-master\ cusplibrary-master\cusp\detail\device\spmv\coo_flat.h 164
Error 5 error C2144: syntax error : 'void' should be preceded by ';' c:\users\administrator\downloads\android\cusplibrary-master\cusplibrary-master\cusp\detail\device\spmv\coo_flat.h 164

22 IntelliSense: expected a ';' c:\Users\Administrator\Downloads\Android\cusplibrary-master\cusplibrary-master\cusp\detail\device\spmv\coo_flat.h 272
...
还有其他108个错误。如果这些是语法错误，为什么没有任何显示在我的CUDA解决方案？如何成功地在C ++项目中构建我的代码？
There are 108 more errors like these. If these are syntax errors, why didn't any of them show up in my CUDA solution? How can I successfully build my code in a C++ project?

推荐答案
现在我想在C ++中的一个书面项目中使用这段代码，但是当我将一个相同的代码添加到一个新的C ++项目...
"Now I want to use this piece of code in a written Project in C++, but when I added that very same code to a new C++ project ... "
这可能不会工作。如果这个代码在C ++项目中的.cpp文件中，它将不起作用。
That probably won't work. If this code is in a .cpp in a C++ project, it won't work.
cusp是一个基于推力构建的模板库CUDA顶部，因此必须通过 nvcc 编译cusp代码 ，即它必须位于VS中的CUDA项目中，而不是普通的C ++项目。
cusp is a template library that is built on top of thrust which is built on top of CUDA, so cusp codes must be compiled by nvcc, i.e. it must be in a CUDA project in VS, not an ordinary C++ project.
因此，请回到在VS中使用CUDA项目的尖点代码。
So go back to using a CUDA project in VS for your cusp codes.
