Matlab + Cuda 2.0 problems I can't compile example

Accelerated Computing CUDA CUDA Programming and Performance

Hi, I know there are similar topics to this problem, but the errormessage that I get is different to others.

My System:
Vista 32bit
Cuda 2.0
MS Visual Professional 2005
Matlab 2007b
Cuda Driver is called “NVIDIADisplayWinVista(178_08)Int.exe”
I have a 8800 GTX

This says the manual:

---- Compile and test the CUFFT interface ----

speed_fft

I have all these files installed and it is in the path-folder. Then I try the first command:

mex fft2_cuda.c -IC:\CUDA\include -LC:\CUDA\lib -lcudart -lcufft

Then I get this:

mex fft2_cuda.c -IC:\CUDA\include -LC:\CUDA\lib -lcudart -lcufft

For the other both compiler-commands

mex fft2_cuda_sp_dp.c -IC:\CUDA\include -LC:\CUDA\lib -lcudart -lcufft
mex ifft2_cuda.c -IC:\CUDA\include -LC:\CUDA\lib -lcudart -lcufft

I get similar messages. When I start

speed_fft

Matlab brakes down. It closes without message.

The only idea that I still have is to install XP 32bit. But does that really help?
Hm, I really need to get that running, I hope someone can help me…

Hi, it works now. I didn’t choose the compiler VS 2005 in matlab. After typing

mex -setup

it all works well now.

This topic can be closed. :-)

sorry, i have the same problem…what have you choosen?

4

He chose the VS2005 compiler.

thanks…i’m sorry but i’ve not read correctly
did VS2008 work correctly with cuda 2.0 and mtlab 2008?

VS2008 is as far as I know only supported from CUDA 2.1
