Qt5 中的 Cuda 链接错误

Question

我开始使用 Qt5.8 中的 Cuda 8.0 和 Qt creator 在 Windows 10 上的 Visual Studio 2015 x64 中，我得到了未解析的符号，例如：

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：

我已经阅读了一些关于在 qt 上配置 cuda 的线程，但似乎没有人遇到这样的错误。我已经复制了 VS 示例链接器设置中出现的所有库文件，但仍然收到错误。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。想知道为什么这个文件没有在示例Visual Studio项目中列出。
