Installation of SVMstruct: mex command not found

I try to install SVMstruct http://www.robots.ox.ac.uk/~vedaldi/code/svm-struct-matlab.html. When executing

   make

I get the following error in my Terminal:

mex CC='gcc' LD='gcc' -largeArrayDims -maci64 CFLAGS='$CFLAGS -m64 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk -mmacosx-version-min=10.4 -Wall' LDFLAGS='$LDFLAGS -Wl,-syslibroot,/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk -mmacosx-version-min=10.4' -outdir "build/maci64/" -c "svm_struct_learn_custom.c"
/bin/sh: mex: command not found
make: *** [build/maci64/svm_struct_learn_custom.o] Error 127

Does someone know how to solve this problem?

Pia - did you download svm-struct-matlab-1.2, or a previous version? Have you built MEX functions before, or is this the first time?

The README_MATLAB.txt indicates that To compile this software use the included Makefile. It should work out of the box on Linux and Mac OS X provided that MATLAB MEX program is in the command line path. So just issue make...

It then goes on to say that if MEX is not on the command line, the path can be specified as

 make MEX=<MATLABROOT>/bin/mex

where MATLABROOT is the path returned by running matlabroot in the MATLAB Command Window.

If that doesn't work, it may be that you don't have a C/C++ compiler installed. In the MATLAB Command Window, type

 mex -setup

What do you see when you do this? When I run the above (on OS X 10.8.5), I see

 MEX configured to use 'Xcode with Clang' for C language compilation.

I had to download Xcode in order to compile C/C++ functions. See Mac OS X supported compilers for details.

Thanks a lot, it works! Adding the path MATLABROOT to the MAKEFILE solved the problem.

I replaced

MEX ?= mex

with

MEX ?= <MATLABROOT>/bin/mex

Great!
