NVMEXOPTS.bat for MatLab 2007b

Accelerated Computing CUDA CUDA Programming and Performance
1

I have for some time now tried, whitout succes, to implement CUDA in MatLab 2007b.

As mentioned I have MatLab 2007b installed on a Windows XP 32-bit machine and ofcause installede the latest CUDA driver, CUDA Toolkit and SDK which were found at nvidia.com today. MS Visual studio 8 is also installed. Further more I tried to follow the instructions in the readme of the CUDA plugin for MatLab.

I am sure that the CUDA installations works properly as I can run any of the examples in the SDK.

The first mex commands goes without any trouble but the nvmex command:
nvmex -f nvmexopts.bat Szeta.cu -IC:\cuda\include -LC:\cuda\lib -lcufft -lcudart

which results in a long serie of errors and finally a Error using ==> nvmex at 206.

nvmex -f nvmexopts.bat Szeta.cu -IC:\cuda\include -LC:\cuda\lib -lcufft -lcudart

??? Error using ==> nvmex at 206

Unable to complete successfully.
But really leaving me no clues of what the error is or why it is caused.
I am new to this but so far I read about different versions of the nvmexopts.bat for different versions of MatLab and since the plugin was testet on 2006b I figured that the error is in that file. Please help me and correct me if my assumptions are wrong about the .bat file.

I have exactly the same problem with Matlab 2007b.
L4rs3n, did you find the way ???

I have seen that some people modified nvmexopts.bat and nvmex.pl so as to make it work on R2008, but I have only R2007 version and don’t know where to make changes on those files :(
Can anybody help ?

Tnks a lot,
Víctor.

Same problem with CUDA toolkit 2.2 and VS2008 (VC9), but unrelated to Matlab.

EDIT: I was able to get this working by ensuring that cl.exe (VC compiler) enables /Zc:wchar_t.

Add “-Xcompiler -Zc:wchar_t” at the end of your NVCC command-line.

Alternatively, make sure nvmexopts.bat does not specify “/Zc:wchar_t-” (note the minus).

Read more about /Zc:wchar_t at: [url=“http://msdn.microsoft.com/en-us/library/dh8che7s(VS.80).aspx”]Microsoft Docs - Developer tools, technical documentation and coding examples

Right ;), tnks eigma. I changed my nvmexopts.bat the way you say, replacing “/Zc:wchar_t-” by “/Zc:wchar_t” at COMPFLAGS, and I think it is compiling now, … as now the error es about linking ;) . → I paste those lines at the end
However, I’m not getting a clear explanation about what is happening.
Anybody has any idea ?

Does anybody know how to fix this? I have no idea what is going wrong, since there is no explicit error, just warnings.

Ok, finally got it to work with the nvmex.pl from http://forums.nvidia.com/index.php?showtopic=74210. … And my own nvmexopts.bat (attached) for WinXP 32, Matlab 2007b, VS8 .
nvmexopts.bat.txt (2.77 KB)

Thanks eigma,

You saved my day(s). External Media

After searching a while I found your very helpful post…replacing “/Zc:wchar_t-” with “/Zc:wchar_t” in nvmexopts.bat rids out my problems
