我正在尝试编译简单的cuda程序（我从Compiling Cuda code in Qt Creator on Windows获取了源代码） 这是我的.pro文件：
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

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

$$CUDA_SDK/common/lib/$$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 \

-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：

所有问题（由于低代表无法发布图片）：issues
如果我没有弄错，那么问题在于将 nvvc.exe 编译的cuda目标文件（vectorAddition_cuda.o）与 cl.exe 和VS libs相关联。然后MinGW（ g ++ 编译器）试图以某种方式将cuda目标文件和c ++目标文件（main.o）与所有库链接到可执行文件中。然而，g ++并不知道VS运行时库，并且正在抛出这些错误。所以我想我需要以某种方式将VS libs传递给g ++。 我该如何解决这个问题？
答案 0 :(得分：1)
我有点困惑，你使用的是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混合。你不能混合那两个。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编译项目，否则将无法正常工作。
我自己从未使用CUDA，但似乎system requirements仅提及Visual Studio 2008,2010和2012.如果你想将它与Qt一起使用，那么你可能只需要使用VS编译Qt （在download page上，两者都有32位和64位的构建。只要不用它创建任何商业应用程序，就可以获得Visual Studio Express for free。
要将QtCreator与MSVC后端编译器一起使用，请转到工具＆gt;选项＆gt;构建并运行＆gt;套件并添加一个新的套件与MSVC编译器，cdb作为调试器和刚刚下载的Qt版本（它必须使用相同的Visual Studio版本编译，否则它将无法工作）。然后打开项目，转到Projects选项卡（左侧）并选择刚刚创建的Kit。在一切顺利进行之前，您应该清理.pro文件。
另外，在您的链接器行中有一些似乎不合适的事情：
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
首先是-L+=，这可能是由QMAKE_LIBDIR末尾的转义反斜杠引起的。
然后语法-L-lmsvcrt似乎错了。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顺便说一句。我只想将LIBS变量用于任何外部依赖。

您可以将这些添加到.pro文件中，该文件用于使用VS2010和Linux在Windows上链接到CUDA：
