In Matlab it try to compile the example in matlab using the instruction in the readme.txt but I get an error.
Dont understand where the mistake is.
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.
Did the setup, still does not work with the same error. <img src=‘http://hqnveipbwb20/public/style_emoticons/<#EMO_DIR#>/crying.gif’ class=‘bbc_emoticon’ alt=‘:’(’ />
Can you post the output of:
-
a verbose build of a simple C mex file: mex -v file.c
-
a verbose output of the cuda mex file: nvmex -v … Seta.cu
dont have problems with mex compilations , but okay:
mex -v ifft2_cuda.c -IF:\CUDA\include -LF:\CUDA\lib -lcudart -lcufft

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. Only MSVC 8.0 and MSVC 9.0 are supported
