c++ - 编译cuda文件报错: "runtime library" mismatch value 'MDd_DynamicDebug' doesn't match value 'MTd_StaticDebug' in vectorAddition_cuda. o

Question

我尝试在 Qt 5.2 和 MSVC2012 环境下编译一个 cuda 文件。在开始我的项目之前，我仔细阅读了问题并回复:Compiling Cuda code in Qt Creator on Windows .但是即使我简单地复制代码并在qt中生成2个文件，仍然会弹出一些错误

/main.cpp
/vectorAddition.cu

错误是:

error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MDd_DynamicDebug' doesn't match value 'MTd_StaticDebug' in vectorAddition_cuda.o

我完全不知道如何修复这个错误。我在网上阅读了一些关于修复 MSVC2012 中的不匹配问题的文章。但很少有人提到如何在 Qt .pro 文件中做到这一点。有没有人碰巧遇到这个问题？

我这里也附上了pro文件(根据我自己的目录稍作修改)

“问题重复”的解释:

我也看了文章Mismatch Detected for 'RuntimeLibrary'但不同的是，我的问题是关于在 Qt 中设置 NVCC，它比在 MSVC 环境中更复杂。即使/MDd 由以下代码设置，如果没有正确设置 NVCC，cu 文件仍然无法编译。运行时库的简单更改并不能完全解决我的问题。正是NVCC的设定最终成就了它。

# MSVCRT link option (static or dynamic, it must be the same with your Qt SDK link option)
MSVCRT_LINK_FLAG_DEBUG = "/MDd"
MSVCRT_LINK_FLAG_RELEASE = "/MD"

Answer 1

我通过阅读另一篇文章解决了我的问题 http://robot9.me/cuda_qtcreator_windows/

作为问题Mismatch Detected for 'RuntimeLibrary'建议。 MSVCRT 链接选项需要保持一致。所以在 NVCC 配置之前添加了 /MDd 设置。

但关键是要正确设置cuda.commands。不同于问题:Compiling Cuda code in Qt Creator on Windows (我试过那个配置但对我不起作用)我的 nvcc 是这样设置的:

   # MSVCRT link option (static or dynamic, it must be the same with your Qt SDK link option)
    MSVCRT_LINK_FLAG_DEBUG = "/MDd"
    MSVCRT_LINK_FLAG_RELEASE = "/MD"

   CONFIG(debug, debug|release) {
    #Debug settings
    # Debug mode
    cuda_d.input    = CUDA_SOURCES
    cuda_d.output   = $$CUDA_OBJECTS_DIR/${QMAKE_FILE_BASE}_cuda.obj
    cuda_d.commands = $$CUDA_DIR/bin/nvcc.exe -D_DEBUG $$NVCC_OPTIONS $$CUDA_INC $$LIBS \
                      --machine $$SYSTEM_TYPE -arch=$$CUDA_ARCH \
                      --compile -cudart static -g -DWIN32 -D_MBCS \
                      -Xcompiler "/wd4819,/EHsc,/W3,/nologo,/Od,/Zi,/RTC1" \
                      -Xcompiler $$MSVCRT_LINK_FLAG_DEBUG \
                      -c -o ${QMAKE_FILE_OUT} ${QMAKE_FILE_NAME}
    cuda_d.dependency_type = TYPE_C
    QMAKE_EXTRA_COMPILERS += cuda_d
}
else {
     # Release settings
     cuda.input    = CUDA_SOURCES
     cuda.output   = $$CUDA_OBJECTS_DIR/${QMAKE_FILE_BASE}_cuda.obj
     cuda.commands = $$CUDA_DIR/bin/nvcc.exe $$NVCC_OPTIONS $$CUDA_INC $$LIBS \
                    --machine $$SYSTEM_TYPE -arch=$$CUDA_ARCH \
                    --compile -cudart static -DWIN32 -D_MBCS \
                    -Xcompiler "/wd4819,/EHsc,/W3,/nologo,/O2,/Zi" \
                    -Xcompiler $$MSVCRT_LINK_FLAG_RELEASE \
                    -c -o ${QMAKE_FILE_OUT} ${QMAKE_FILE_NAME}
     cuda.dependency_type = TYPE_C
     QMAKE_EXTRA_COMPILERS += cuda
}

虽然我还没有完全理解一些cuda.commands，但它确实有效。请引用http://docs.nvidia.com/cuda/cuda-compiler-driver-nvcc/index.html#axzz3FOBrgXpc有关 NVCC 配置的更多详细信息。
