在QTCreator中使用MinGW编译c ++和cuda代码 [英] Compiling c++ and cuda code with MinGW in QTCreator

问题描述

我试图编译简单的cuda程序（我从获取源代码在Windows上编译Qt Creator中的Cuda代码）
这是我的.pro文件：

Im trying to compile simple cuda program (i took source code from Compiling Cuda code in Qt Creator on Windows) This is my .pro file:

TARGET = Cuda

# Define output directories
DESTDIR = release
OBJECTS_DIR = release/obj
CUDA_OBJECTS_DIR = release/cuda

# Sourcefiles
SOURCES += main.cpp

# This makes the .cu files appear in your project
OTHER_FILES +=  vectorAddition.cu

# CUDA settings <-- may change depending on your system
CUDA_SOURCES += vectorAddition.cu

CUDA_SDK = "C:/Cuda/CudaSamples"   # Path to cuda SDK install
CUDA_DIR = "C:/Cuda/CudaToolkit"            # Path to cuda toolkit install
SYSTEM_NAME = Win32         # Depending on your system either 'Win32', 'x64', or 'Win64'
SYSTEM_TYPE = 32            # '32' or '64', depending on your system
CUDA_ARCH = sm_11           # Type of CUDA architecture, for example 'compute_10', 'compute_11', 'sm_10'
TEMP = 'C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin' #tried to add VS compiler path, seems woring. When i changed it to higher version error appeared
VS = $$join(TEMP,'" -ccbin "','-ccbin "','"') #joing path to VS compiler with quotes
NVCC_OPTIONS = --use_fast_math $$VS

# include paths
INCLUDEPATH += $$CUDA_DIR/include \
               $$CUDA_SDK/common/inc/ \
               $$CUDA_SDK/../shared/inc/ \

# library directories
QMAKE_LIBDIR += $$CUDA_DIR/lib/$$SYSTEM_NAME \
                $$CUDA_SDK/common/lib/$$SYSTEM_NAME \
                $$CUDA_SDK/../shared/lib/$$SYSTEM_NAME \
                C:/CUDA/VS10/VC/lib \   #tried to add VS runtime libraries, after that some errors disappeared, and some new emerged so i guess it worked
QMAKE_LIBS += -lmsvcrt -llibcmt -llibcpmt #after adding VS runtime to QMAKE_LIBDIR this line seems to have no effect
# Add the necessary libraries
LIBS += -lcuda -lcudart
#LIBS += -lmsvcr100
QMAKE_CFLAGS_RELEASE += -v
MSVCRT_LINK_FLAG_DEBUG   = "/MTd"
MSVCRT_LINK_FLAG_RELEASE = "/MT"

# The following makes sure all path names (which often include spaces) are put between quotation marks
CUDA_INC = $$join(INCLUDEPATH,'" -I"','-I"','"')
#this was nested in CONFIG (see link above) but i dont think it worked
    cuda.input = CUDA_SOURCES
    cuda.output = $$CUDA_OBJECTS_DIR/${QMAKE_FILE_BASE}_cuda.o
    cuda.commands = $$CUDA_DIR/bin/nvcc.exe $$NVCC_OPTIONS $$CUDA_INC $$LIBS --machine $$SYSTEM_TYPE -arch=$$CUDA_ARCH \
                    -Xcompiler "/wd4819,/EHsc,/W3,/nologo,/O2,/Zi" \ 
                    -Xptxas -v \
                    -Xcompiler $$MSVCRT_LINK_FLAG_RELEASE \
     -c -o ${QMAKE_FILE_OUT} ${QMAKE_FILE_NAME} #Xptxas -v is command for some extra output during cuda compiling (nvvc). -Xcompiler, honesly i have no idea what "/wd4819,/EHsc,/W3,/nologo,/O2,/Zi" \ means,i copied those from some chinese webpage and again some errors went away
    cuda.dependency_type = TYPE_C
    QMAKE_EXTRA_COMPILERS += cuda

HEADERS += \
    vectorAddition.h #empty header, i was just trying something.

这是编译器输出：

和所有问题（由于低代表不能张贴图片）：问题

And all issues (Can't post images due low rep): issues

如果没有弄错，那么问题是链接cuda对象文件（vectorAddition_cuda.o），它由 nvvc.exe 与 cl.exe 和VS libs编译。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lib链接到可执行文件中。 g ++然而不知道VS运行时库和抛出这些错误。所以我想我需要以某种方式传递VS libs到g ++。
我如何解决这个问题？

If im not mistaken, then problem is with linking cuda object file (vectorAddition_cuda.o) which is compiled by nvvc.exe with cl.exe and with VS libs. Then MinGW(g++ compiler) is trying somehow link together cuda object file and c++ object file (main.o) with all libs into the executable file. g++ however doesnt know about VS runtime libs and is throwing these errors. So i guess i need somehow pass VS libs to g++. How can i fix this?

推荐答案

我有点困惑，你使用MinGW还是Visual？标题似乎声明你正在使用MinGW，但项目文件似乎使用两者的混合。你不能混合这两个。如果你编译（或直接从NVidia下载二进制文件）CUDA与Visual Studio 2010，你必须使用VS10编译你的项目，否则它将无法工作。

I'm a bit confused, are you using MinGW or Visual? The title seems to state that you are using MinGW but the project file seems to use a mix of both. You can't mix those two. If you compiled (or downloaded the binary directly from NVidia) CUDA with Visual Studio 2010, you HAVE to use VS10 to compile your project, otherwise it won't work.

我从来没有使用过CUDA，但似乎系统需求只提到Visual Studio 2008,2010和2012.如果你想要使用它与Qt，这是可能的，你只需要抓住一个Qt编译VS（有生成32和64位的两个在下载页面上，您可以获得Visual Studio Express 免费，只要您不使用它创建任何商业应用程序。

I never used CUDA myself but it seems that the system requirements mention only Visual Studio 2008, 2010 and 2012. If you want to use it with Qt, it's possible, you just have to grab a Qt compiled with VS (there are builds for 32 and 64 bit for both on the download page. You can get Visual Studio Express for free as long as you don't create any commercial application with it.

要使用QtCreator与MSVC后端编译器，请转到工具>选项>构建和运行>套件，并添加一个新的工具包与MSVC编译器，cdb作为调试器和您刚刚下载的Qt版本（它必须已使用相同的Visual Studio版本编译，否则它将无法工作）。然后打开您的项目，转到Projects选项卡（左侧），选择您刚刚创建的Kit。你应该可以清理你的.pro文件，一切顺利。

To use QtCreator with the MSVC backend compiler go to Tools > Options > Build and Run > Kits and add a new Kit with the MSVC compiler, cdb as the debugger and the Qt version you just downloaded (it must have been compiled with the same Visual Studio version otherwise it won't work). Then open your project, go to the Projects tab (on the left) and select the Kit you just created. You should probably clean your .pro file as well before everything work smoothly.

在旁注中，有一些东西似乎不在你的链接器行：

On a side note, there are a few things that seems out of place in your linker line:

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 + = ，可能是由结尾的转义反斜杠引起的 Q-MAKE_LIBDIR 。

First this -L+=, which might be caused by the escaping backslash at the end of the QMAKE_LIBDIR.

然后语法 -L-lmsvcrt 似乎错了。这可能是因为你使用 QMAKE_LIBS ，我个人从来没有使用它，根据文档，因为它是一个内部变量。同样适用于 QMAKE_LIBDIR btw。我只需使用 LIBS 变量作为任何外部依赖。

Then the syntax -L-lmsvcrt seems wrong. It might be because you are using QMAKE_LIBS, I personally never had to use it, and according to the documentation you shouldn't either as it is an internal variable. Same goes for QMAKE_LIBDIR btw. I would just use the LIBS variable for any external dependency.
