Qt5中的Cuda Link错误

Question

我开始在Qt5.8中使用Cuda 8.0，在Windows 10上使用Qt创建者和Visual Studio 2015 x64，我得到了未解析的符号，如：

cuda_code_cuda.o : error LNK2019: 澷朄夝愅揑奜晹晞崋 atexit丆
cuda_code_cuda.o : error LNK2019: 澷朄夝愅揑奜晹晞崋 cudaDeviceSynchronize丆
cuda_code_cuda.o : error LNK2019: 澷朄夝愅揑奜晹晞崋 cudaConfigureCall丆
cuda_code_cuda.o : error LNK2019: 澷朄夝愅揑奜晹晞崋 cudaSetupArgument丆
cuda_code_cuda.o : error LNK2019: 澷朄夝愅揑奜晹晞崋 cudaLaunch丆
cuda_code_cuda.o : error LNK2019: 澷朄夝愅揑奜晹晞崋 __imp_fminf丆
...

我的.pro文件看起来像：

    cuda.dependency_type = TYPE_C
    QMAKE_EXTRA_COMPILERS += cuda
}

我已经阅读了一些关于在qt上配置cuda的线程，但似乎没有人得到像这样的错误。我复制了VS示例链接器设置中出现的所有lib文件，但仍然得到错误。我该怎么办？

Answer 1

我现在解决了这个问题，这是通过将msvcrt添加到lib列表中来实现的。想知道为什么此文件未在示例Visual Studio项目中列出。
