编译C++和CUDA代码的MinGW在QTCreator

我试着去编写简单的CUDA程序（我把源代码Compiling Cuda code in Qt Creator on Windows）这是我的.pro文件：编译C++和CUDA代码的MinGW在QTCreator

TARGET = Cuda 

# Define output directories

    cuda.dependency_type = TYPE_C 
    QMAKE_EXTRA_COMPILERS += cuda

而且所有的问题（不能张贴由于图像的低REP）：issues

如果我不是错，那么问题是与链接CUDA OBJ ect文件（vectorAddition_cuda.o），它由nvvc.exe编译cl.exe和VS库。然后MinGW（g ++编译器）试图以某种方式将cuda对象文件和C++对象文件（main.o）与所有库链接到可执行文件中。但是g ++不知道VS运行库，并且抛出了这些错误。所以我想我需要以某种方式将VS库传递给g ++。我该如何解决这个问题？

您是否尝试过的完整路径链接到CUDA和cudart？我发现有时调试和解决这类问题更容易。尝试如下所示：'LIBS + = C：/Cuda/CudaToolkit/cuda.lib C：/ Cuda/CudaToolkit/cudart.lib'。一旦它工作，你可以使用变量并清理你的.pro文件。 – Uflex

我试过这个，它不工作，我不认为你可以链接库像LIBS变量那样（从-l判断）。无论如何，我更新编译器输出显示全过程（qmake - >重建项目）。如果您现在查看编译器输出，则nvvc命令似乎正在工作 – Newbie

我有点困惑，你使用MinGW还是Visual？标题似乎表明您正在使用MinGW，但项目文件似乎使用了两者的组合。你不能混合这两个。如果您使用Visual Studio 2010编译（或直接从NVidia下载二进制文件）CUDA，则必须使用VS10编译您的项目，否则它将无法工作。

我从来没有使用过CUDA，但似乎system requirements只提到Visual Studio 2008,2010和2012.如果你想使用它与Qt，这是可能的，你只需要抓住用VS编译的Qt（有在download page上为32位和64位构建，只要你没有创建任何商业应用，你就可以获得Visual Studio Express for free

要使用QtCreator和MSVC后端编译器，请转到Tools> Options > Build and Run> Kits，添加一个带有MSVC编译器的新工具包，作为调试器的cdb和刚刚下载的Qt版本（它必须使用相同的Visual Studio版本进行编译，否则将无法工作）。项目，转到项目选项卡（在左边t）并选择您刚刚创建的套件。在所有工作顺利进行之前，您应该先清理.pro文件。

在一个侧面说明，有一些在你的连接线显得格格不入几件事情：

g++ -Wl,-s -Wl,-subsystem,windows -mthreads -o release\Cuda.exe release/cuda/vectorAddition_cuda.o release/obj/main.o -lglu32 -lopengl32 -lgdi32 -luser32 -lmingw32 -lqtmain -LC:\Cuda\CudaToolkit\lib\Win32 -LC:\Cuda\CudaSamples\common\lib\Win32 -LC:\Cuda\CudaSamples\..\shared\lib\Win32 -LC:\CUDA\VS10\VC\lib -LQMAKE_LIBS -L+= -L-lmsvcrt -L-llibcmt -L-llibcpmt -lcuda -lcudart -LF:\Programs\Qt5.1.1\5.1.1\mingw48_32\lib -lQt5Gui -lQt5Core

首先这个-L+=，这可能是由逃逸反斜线在QMAKE_LIBDIR结束所致。

然后语法-L-lmsvcrt看起来不对。这可能是因为你使用的是QMAKE_LIBS，我个人从来没有使用它，根据the documentation，你不应该因为它是一个内部变量。同样适用于QMAKE_LIBDIR btw。我只是使用LIBS变量来处理任何外部依赖。

因此，我不能使用CUDA windows二进制文件进行g ++编译。如果我想使用QT和CUDA，我需要使用Linux和CUDA for linux编译使用gcc吗？ – Newbie

我编辑了我的答案，因为它不适合评论，希望它有助于澄清 – Uflex

非常好，谢谢。我会尽快尝试。 – Newbie

感谢您的.pro文件。我已经拥有了其中的大部分，但他们并没有在错误的QT版本中工作。我现在可以使用它们（下载VS编译的QT版本）。 – Newbie
