Error using mex: No supported compiler or SDK was found.

I have MATLAB 2014a and VS 2012 ultimate, I don't know why this is happening. I am trying to compile a cuda file. Please help.

I ran mex -setup -v and this was the output:

>> mex -setup -v

[Friedrich]

Hi,

compiling a .cu file in MATLAB is not possible out of the box (mex -setup does not configure the compiler for compilation of CUDA code). You would need some further steps. See here or run in MATLAB

>>web(fullfile(docroot, 'distcomp/run-mex-functions-containing-cuda-code.html#btrgjh3-1'))

In addition you would need to adjust that XML file to match VS 2012 because it's configured for VS 2010.

[Jordan]

Thanks for the reply. So I followed that web guide exactly. I configured the XML file (original version posted below)

So that the line "<envVarExists name="VS100COMNTOOLS" />" is now "<envVarExists name="VS110COMNTOOLS" />"

Did I do the XML update correctly? I am still getting errors. I posted the complete error in a response above.

Many thanks.

[Friedrich]

Where did you copy that XML file to? From the output above it seemed like the normal xml file (the one mex -setup creates) was picked up. In addition do you have a CUDA Toolkit installed? If not please do so by downloading it from here. If yes, make sure the locations and paths in that xml file are matching your CUDA Toolkit installation.

[Jordan]

The same folder as the cuda file that I was trying to compile. I have the CUDA toolkit, yes.

[Friedrich]

Do what Ken said above. It seems like your have a mexopts.bat file which has a higher priority than any other xml file. Remove it ( C:\Users\Jordan Bonilla\AppData\Roaming\MathWorks\MATLAB\R2014a\mexopts.bat ) and try again.

[Jordan]

I made some tweaks and now I am getting the error that the source file is unrecognized... I am just going to call mathworks

Answer 2

[Titus Edelhofer]

Hi Jordan,

to me this looks fine: you configured mex to use Microsoft Visual C++ 2012 (as in the text directly before the warning about large arrays). You shouldn't have any problems, at least none that I can see ;-).

Titus

Answer 3

[Jordan]

Thanks for the reply. I should also mention that this error happened when I attempted to compile a cuda file using the command:

 mex myfile.cu

[Titus Edelhofer]

Hi Jordan,

but I don't see an error? Please try

mex -v myfile.cu

and post the output of this command ...

Titus

[Jordan]

Here it is. Thanks in advance.

Try removing/renaming the mexopts.bat file cited above, then rerun MEX with -v... Any change?

[Jordan]

no change. I'm just gonna open a support request with mathworks.
