Windows 10中的CUDA 7.5（来自Theano项目）链接错误：MSVCRT.lib错误LNK2019：无法解析的外部符号

Question

我想正确设置CUDA以便利用Theano中的GPU。

通过调整我的.theanorc和nvcc.profile文件修复大量的编译问题后，我在努力解决这个链接错误：

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 

这里是我的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  += 

看来这不是一个不常见的错误，但一般修复涉及changing some setting in the Visual Studio project。但是，在这里我没有Visual Studio项目。代码由Theano动态生成并在运行时编译。

相关的系统设置：

• 的Windows 10（是...）
• 的Python 2.7.10 64位（蟒蛇DISTRIB）
• CUDA 7.5/NVIDIA驱动程序353.54 /的GeForce GTX 760
• Visual Studio Community 2013

该死！我在发布这个问题后才发现它。解决办法：略有不同和库文件夹：

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  += 

我特别切换从：

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

到：

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

（我认为我不得不使用Program Files者因为我的64位项目，但实际上64位文件也包含在Program Files (x86)）

我也要感谢你。我一直试图让这个工作几个小时，这是让我超越边缘的帖子。我的配置稍有不同，所以我的实际链接不同。我张贴他们的情况下，它可以帮助别人

.theanorc

[global] 
device = gpu 
floatX = float32 

[nvcc] 
flags = --use-local-env --cl-version=2008
