I've been using CUDA for the past couple of months on a 64 bit windows 7 installation along with Visual Studio 2008. Recently i shifted to a 32 bit windows 7 installation and also updated my graphics card, which earlier was a 8600GTX and now is a GTX465. I've installed the relevant driver and the CUDA 3.1 toolkit, and am still using VS2008

Somehow if i try and compile the same Visual studio projects I'd used earlier, I get the following output in the build window.

1>------ Build started: Project: CUDAServicenew, Configuration: Debug Win32 ------
1>Performing Custom Build Step
1>CUDAHelloWorld.cu
1>Catastrophic error: cannot open source file      "C:/Windows/TEMP/tmpxft_0000082c_00000000-6_CUDAHelloWorld.cpp1.ii": not a regular file
1>1 catastrophic error detected in the compilation of "C:/Windows/TEMP/tmpxft_0000082c_00000000-6_CUDAHelloWorld.cpp1.ii".
1>Compilation terminated.

1>CUDAServicenew - 1 error(s), 0 warning(s)
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

I've used a custom build rule as shown below

“$(CUDA_BIN_PATH)\nvcc.exe” -ccbin “$(VCInstallDir)bin” -c -D_DEBUG -DWIN32 -D_CONSOLE   D_MBCS -Xcompiler /EHsc,/W3,/nologo,/Od,/Zi,/RTC1,/MTd --ptxas-options -v - I”$(CUDA_INC_PATH)” -I./ -o $(ConfigurationName)\CUDAHelloWorld.obj CUDAHelloWorld.cu

This happens even when i try to compile the SDK samples provided by NVIDIA. I can't understand why the cpp1.ii file is not being opened, what is it that I'm doing wrong here? Any help would be greatly appreciated.

Thank you,

+1  A: 

Just to check a few random (i.e. unlikely) ideas...

  1. Did you install the 32-bit toolkit?
  2. Are you running VS as administrator?
  3. Is C:\Windows\TEMP writeable?
  4. Do you have disk space?

VS2005 always needed to be run as administrator (even without CUDA) and while 2008 is less strict it is required for some operations, so just checking.

Yes, the C:\Windows\Temp folder was not writable, ensuring that solved the problem. Thank you so much
