Cannot compile the source code under Win8.1 + VS2013 Update 5 about cntk HOT 5 CLOSED

Hi xqyd,

We could not reproduce this on our machine (also VS2013 update5, Win 8.1). It seems that the your environment is somehow broken (usually the 'size_t' problem indicates x86/64 bit problems).

Could you provide more information regarding your environment (compiler version, PATH)? Also if you go to the "Configuration Properties -> C/C++ -> General" of SequenceTrainingLib project, and change the "Supress Startup Banner" to "No", and try to rebuild, what is the output?

Thanks!

Hi eldakms,
I figured this out by find that the vs2010 and vs2013 has mixed c1.dll and c2.dll. After uninstall vs2010, the 'size_t' problem was gone!
And the SequenceTrainingLib can be build successfully.
However, I am still having difficulties in compiling the MathCUDA project, the error output is in the attached file. It said

"error MSB3721: The command ""C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.0\bin\nvcc.exe" -gencode=arch=compute_20,code="compute_20,compute_20" --use-local-env --cl-version 2013 -ccbin "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\bin\x86_amd64" -I..\Common\include\ -I"C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.0\include" -I"C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.0\include" -lineinfo --keep-dir x64\Debug -maxrregcount=0 --machine 64 --compile -cudart static -Xcudafe "--diag_suppress=field_without_dll_interface" -g -use_fast_math -D_DEBUG -DNO_SYNC -DWIN32 -D_WINDOWS -D_USRDLL -DMATH_EXPORTS -DUSE_CUDNN -D_UNICODE -DUNICODE -Xcompiler "/EHsc /W4 /nologo /Od /Zi /RTC1 /MDd /WX" -o x64\Debug\MathCUDA\GPUTensor.cu.obj "D:\2015erdos\Install CNTK\CNTK-master\CNTK-master\Source\Math\GPUTensor.cu"" exited with code 2."

Any idea what's this for?
Thanks a lot!!!

It seems you have some invalid characters in your Cuda installation (see the warning):
1>c:\program files\nvidia gpu computing toolkit\cuda\v7.0\include\math_functions.h : error C2220: warning treated as error - no 'object' file generated
1>c:\program files\nvidia gpu computing toolkit\cuda\v7.0\include\math_functions.h : warning C4819: The file contains a character that cannot be represented in the current code page (936). Save the file in Unicode format to prevent data loss

Thank you!

Hi eldakms,
Thanks for the hint. Although I did not touch the cuda installation, it is found that the system locale has to be English for CNTK. I was using Chinese locale for my Win8.1 before.

However, after changing the system locale, I've run into another problem that the xcopy does not work properly. And the reason is that it does not support long path, so after I copied the whole solution to the C:\CNTK-master, everything starts to work!!!

So here're the lessons I've learned in compiling CNTK under win8.1+vs2013 update 5:

1. Set the system locale to English.
2. Use short path to save the source code/solution files.
3. Only VS2013 can work well with the CNTK, do not mix with other version of visual studios.

We will track this with issue #47
