Question

I am now installing a code on my mac.

The code is from here. Look for “Benchmark and Boundary Detection Code” in this page.

In the readme file, it says:

(1) For the image and segmentation reading routines in the Dataset
directory to work, make sure you edit Dataset/bsdsRoot.m to point to
your local copy of the BSDS dataset.

(2) Run ‘gmake install’ from this directory to build everything. You
should then probably put the lib/matlab directory in your MATLAB path.

(3) Read the Benchmark/README file.

For the 1st step, I did as suggested.
For the 2nd step, I am pretty confused. I ran command gmake install in MATLAB, however, I got:

gmake

Undefined function or variable 'gmake'.

Actually, before running MATLAB, I installed gmake port through macports.

I just did it in terminal, however, this is what I got…

hou229:segbench yaozhongsong$ cd /Users/yaozhongsong/Documents/MATLAB/segbench
hou229:segbench yaozhongsong$ sudo gmake install
gmake[1]: execvp: ../Util/gethosttype: Permission denied
gmake[1]: Entering directory `/Users/yaozhongsong/Documents/MATLAB/segbench/Util'
GNUmakefile-library:26: *** mexSuffix not defined.  Stop.
gmake[1]: Leaving directory `/Users/yaozhongsong/Documents/MATLAB/segbench/Util'
hou229:segbench yaozhongsong$

In MATLAB, I also did like this:

!gmake install
/bin/bash: gmake: command not found

How to do the 2nd step in readme file?

Thanks in advance!

Answer 1

For the “mexSuffix not defined” error, first run mexext inside MATLAB, take that output (I suspect it is mexmaci64), edit the file Util/GNUmakefile-library and add the following at line 24:

mexSuffix := mexmaci64

replace the value with the one you get from mexext

Note: I haven’t tested any of this, I am on a Windows machine..
