Changing Makefile to ensure MEX points to matlab mex binary

I have downloaded a repository from the following link

https://bitbucket.org/jaderberg/eccv2014_textspotting/downloads

to run the code it is mentioned that " Edit matconvnet/Makefile to ensure MEX points to your matlab mex binary."

https://bitbucket.org/jaderberg/eccv2014_textspotting

So I opened the Makefile in vi and found following lines of code to edit

*Makefile contents*

http://paste.ubuntu.com/23490952/

*Now my question is where to locate matlab mex binary path?*

*My effort*

I did following command in my ssh shell environment

    locate matlab | grep mex

http://paste.ubuntu.com/23490937/

Still not getting how to edit MEX path in Makefile so that it points to matlab mex binary also How to use ENABLE_GPU?

If I were you I would download MatConvNet directly from their own site ( http://www.vlfeat.org/matconvnet/ ) and follow their instructions. This will be much more up-to-date and hopefully the instructions will be clearer.

[Naseer Khan]

Can you please elaborate a bit I did not get your point?

[Joss Knight]

This guy has included a version of MatConvNet in his git repository. It is out of date.

[Naseer Khan]

Please tell me the specifics so that, that code could get run?

This isn't really a MATLAB question, it's a question for the author of the package you're trying to use. The location of the 'mex executable' is the "bin" directory of your MATLAB installation. But what is going on here is that you need to understand more about the software you are trying to use in order to replicate the results.

Try contacting the author, reading the MatConvNet documentation, and reading the MATLAB documentation on MEX. Once you are more familiar with all the tools involved, you may have some more pertinent and specific MATLAB questions that you can bring back to this forum.

The mex script location is

fullfile(matlabroot, 'bin', 'mex')

I am getting now following error after updating the path

        -output <resultname>
            Create mex-file named <resultname>. The appropriate mex-file
            extension is automatically appended. Overrides mex's default
            mex-file naming mechanism.

So try changing the -o "matlab/mex/gconv.mexa64" to -output "matlab/mex/gconv"
