64-bit compile of .cu to .ptxw64 --> 'cannot execute c1xx.dll' (error D8027)

Hi all,

I'm setting up an environment for 64-bit Matlab/cuda kernel-development. Basically I want to be able to compile .cu files into 64-bit .ptx files so that I can load a cuda kernel to Matlab and utilize it with feval.

I call nvcc with the following line:

nvcc -m 64 -ptx -Xptxas=-v -arch sm_20 -ccbin "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin" -I "C:\Program Files\MATLAB\R2013a/extern/include" applyScaleFactors.cu --output-file applyScaleFactors.ptxw64

I get the following error:

 cl : Command line error D8027 : cannot execute 'C:/Program Files (x86)/Microsoft Visual Studio 10.0/VC/bin/../../VC/bin/amd64\c1xx.dll'

Any ideas on how to solve this would be really helpful!

Background:

• Windows 7 (64-bit)
• Matlab 2013a (64-bit)
• NVIDIA GPU Computing Toolkit 4.1 (64-bit)
• Visual Studio 2010 Professional (32-bit)
• Windows SDK 7.1 (64-bit) installed as described here: http://www.mathworks.se/support/solutions/en/data/1-FPLDGV/

Problem solved!

I had during previous troubleshooting placed a the files cl.exe and vcvars32.bat in my .cu project folder. Removing these solved my issue.
