C++ 编译cuda文件错误："；“运行库”；不匹配值'；MDd#U DynamicDebug'；不'；t匹配值'；MTd#U静态调试'；矢量加法

我尝试在Qt5.2和MSVC2012环境中编译cuda文件。 在我开始我的项目之前，我仔细阅读了以下问题并回答：。 尽管我只是简单地复制了代码并在qt中生成了2个文件，但仍然会出现一些错误

/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bug。我在网上读了一些关于在MSVC2012中修复不匹配的文章。但是很少有人提到如何在Qt.pro文件中实现这一点。有谁碰巧有这个问题吗

我还将pro文件附在这里（根据我自己的目录进行了轻微修改）

对“问题重复”的解释：

我也读了这篇文章 但不同的是，我的问题是关于NVCC在Qt中的设置，这比在MSVC环境中更复杂。尽管/MDd是由以下代码设置的，但如果没有正确的NVCC设置，cu文件仍然无法编译。运行库的简单更改并没有完全解决我的问题。这是NVCC的设置最终做出的

# 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"

---

我通过阅读另一篇文章解决了我的问题

正如问题所暗示的那样。MSVCRT链接选项需要保持一致。因此，在NVCC配置之前添加了

/MDd

设置

但关键是正确设置

cuda.commands

。与问题不同：（我尝试了那个配置，但不适合我） 我的nvcc设置如下：

   # 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
}

尽管我仍然不完全理解一些cuda.commands，但它确实有效。 有关NVCC配置的更多详细信息，请参阅
