Link Windows 10 中的 CUDA 7.5 错误（来自 Theano 项目）：MSVCRT.lib 错误 LNK2019：未解析的外部符号

Question

我正在尝试正确设置 CUDA 以利用 Theano 中的 GPU。

通过调整我的 .theanorc 和 nvcc.profile 文件修复了许多编译问题后，我正在努力修复此链接错误：

这是我的 .theanorc 文件：

[global]
device = gpu
floatX = float32

[cuda]
root = C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.5

[nvcc]
flags = --use-local-env  --cl-version=2013 -LC:\Users\niluje\Anaconda\Lib;
compiler_bindir=C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\amd64

这是我的 nvcc.profile 文件：

TOP              = $(_HERE_)/..

NVVMIR_LIBRARY_DIR = $(TOP)/nvvm/libdevice

PATH            += $(TOP)/open64/bin;$(TOP)/nvvm/bin;$(_HERE_);$(TOP)/lib;

INCLUDES        +=  "-I$(TOP)/include" "-IC:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include" "-IC:\Program Files\Microsoft SDKs\Windows\v6.0A\Include" $(_SPACE_)

LIBRARIES        =+ $(_SPACE_) "/LIBPATH:$(TOP)/lib/$(_WIN_PLATFORM_)" "/LIBPATH:C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\lib\amd64" "/LIBPATH:C:\Program Files\Microsoft SDKs\Windows\v6.0A\Lib"

CUDAFE_FLAGS    +=
PTXAS_FLAGS     +=

这似乎不是一个罕见的错误，但一般修复涉及 changing some setting in the Visual Studio project。但是，这里我没有 Visual Studio 项目。代码由Theano动态生成，运行时编译。

相关系统设置：

Windows 10（是...）
Python 2.7.10 64 位（Anaconda 发行版）
CUDA 7.5 / NVIDIA 驱动程序 353.54 / GeForce GTX 760
Visual Studio 社区 2013

妈的！我在发布问题后就想通了。解决方案：包含和库文件夹略有不同：

TOP              = $(_HERE_)/..

NVVMIR_LIBRARY_DIR = $(TOP)/nvvm/libdevice

PATH            += $(TOP)/open64/bin;$(TOP)/nvvm/bin;$(_HERE_);$(TOP)/lib;

INCLUDES        +=  "-I$(TOP)/include" "-IC:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\include" "-IC:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Include" $(_SPACE_)

LIBRARIES        =+ $(_SPACE_) "/LIBPATH:$(TOP)/lib/$(_WIN_PLATFORM_)" "/LIBPATH:C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\lib\amd64" "/LIBPATH:C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Lib\x64"

CUDAFE_FLAGS    +=
PTXAS_FLAGS     +=

特别是我切换自：

C:\Program Files\Microsoft SDKs\Windows\v6.0A\

至：

C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A

（我以为因为我的 64 位项目我必须使用 Program Files，但实际上 Program Files (x86) 中也包含 64 位文件）

我还要谢谢你。几个小时以来，我一直在努力让它工作，而正是 post 让我无法自拔。我的配置略有不同，所以我的实际链接也不同。我正在 post 联系他们，以防对其他人有帮助
