How to select compiler if not available on the list provided by mex -setup ??

Hi, i have just downloaded the matlab toolbox:

http://www.mathworks.com/matlabcentral/fileexchange/29115-gltreepro-nearest-neighbour-library/content/BuildGLTree3D.m

The mex function is asking me for a compiler. Microsoft Visual C++ express 2010 is already installed. I have followed the instructions of the Mex-setup function which is unable to locate this compiler. How can i compile the few .cpp file i need? Or how can find my compiler? Thanks

Is your system 32 bit Windows or 64 bit?

Thank you!

I am trying it out.

Sorry but i have been through all the steps indicated and I still end up with an error when compiling. All files are in the same folder. Here is the command i put in Matlab:

mex BuildGLTree3DFEX.cpp

C:\PROGRA~1\MATLAB\R2010A\BIN\MEX.PL: Error: 'BuildGLTree3DFEX.cpp' not found.

To cross-check: the URL you posted first was for a single .m file only. Did you download and unzip the entire archive? In MATLAB, what do you see if you ask

ls BuildGLTree3DFEX.cpp

and

ls B*.*

[Simon]

>> ls BuildGLTree3DFEX.cpp

BuildGLTree3DFEX.cpp not found.

>> ls b**

boot.ini

Well, i don't understand something. do the .cpp files need to be in the bin folder of Matlab?, i have also tried to extract them somewhere else, and i have:

ls BuildGLTree3DFEX.cpp

BuildGLTree3DFEX.cpp

>> mex BuildGLTree3DFEX.cpp

BuildGLTree3DFEX.cpp

Looks a little bit better...

[Walter Roberson]

The files do not need to be in the bin folder (and being there is a bad idea), but you _do_ have to be cd()'d to the directory they are in.

For the other matter, see the solutions here:

http://www.mathworks.com/matlabcentral/newsreader/view_thread/281754

[Simon]

And yes, i have unzip the entire archive.

[Simon]

Sorry, but i am not very familiar yet with programming out of Matlab. So there are few explanation on the page you just gave, but very unclear to me.

Neither in the file yvals.h nor matrix.h there is a command line

namespace mat

If i follow instruction given by Fifo, the line number he gave seems irrelevant to me for the file matrix.h. Which solution should i follow?

[Walter Roberson]

I would suggest doing it the way Venn suggests. Go in to yvals.h and find the line that has

#include <matrix.h>

and change it to

namespace mat {

#include <matrix.h>

}

[Simon]

yvals.h does not have such line. I have posted a question for Venn, hopefully he will answer me.

Thanks a lot!

it is a Windows 64bit with Matlab 2010a installed.
