In Matlab it try to compile the example in matlab using the instruction in the readme.txt but I get an error.

The script is using Visual studio. Run " mex -setup" to select Visual Studio as your default compiler for mex. There are instructions on the web on how to use Visual Studio Express if you don’t have the full version. ---

Can you post the output of: 1. a verbose build of a simple C mex file: mex -v file.c 2. a verbose output of the cuda mex file: nvmex -v … Seta.cu ---

Hello All I’m new here… I just begin with Cuda and as it seems i’m not only to have some problem for using/installing it I NEED HELP : So I have VS05, I’ve installed the SDK the toolkit and i want to use cuda with MATLAB…? I can compile Mex File, but when i try to compile cuda file (the example) i have : nvcc fatal : Could not open input file C:\DOCUME~1\rootlocal\Local Settings\Temp/tmpxft\_00000430\_00000000-1 C:\PROGRA~1\MATLAB\R2007B\BIN\NVMEX.PL: Error: Compile of ‘Szeta.cu’ failed. Somebody know what can i do Thks a lot ---

I am getting the same error. I have set my compiler to Microsoft Visual Studio 2008 (done using the mex -setup command), and am using Matlab 2008a. When I try to compile, I get the following error. Please let me know what I can do to fix this. Thanks! nvmex -f nvmexopts.bat Szeta.cu -IC:\cuda\include -LC:\cuda\lib -lcufft -lcudart nvcc fatal : nvcc cannot find a supported cl version.
