I had the same problem with Student version of Matlab R2011a, and OS X 10.7.2
None of the solution above worked for me.

What worked is actually following.

>> !DYLD_LIBRARY_PATH=”;/opt/local/bin/convert file1.eps file2.png

You don’t need to change any environmental variables, and symbolic links from default settings. Matlab environmental variable is not altered by this command.
In the normal command line, DYLD_LIBRARY_PATH is not set, but it is set in MATLAB. By temporarily removing it, convert can load the library from the appropriate path.

Hope it helps someone.

when inputting:
setenv(‘DYLD_LIBRARY_PATH’,['/opt/local/lib/:' getenv('DYLD_LIBRARY_PATH')])

[s,w] = system(‘/opt/local/bin/convert -crop 400×200+0+0 bb1.tif bb2.tif’);

I get error:
dyld: Symbol not found: __cg_jpeg_resync_to_restart
Referenced from: /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/Versions/A/ImageIO
Expected in: /opt/local/lib//libjpeg.8.dylib
in /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Frameworks/ImageIO.framework/Versions/A/ImageIO

I want to mention that there’s always more than one way to do something, and it may be easier for you to use the convert command from the ImageMagick toolbox, by calling it with a system call in Matlab.

The setenv command in Matlab is very much available on the Windows platform.

I don’t understand that if it’s just a newer version of libtiff you’re trying to use, that you don’t use that library compiled for Windows(!) My guess is you will probably not be able to use libraries from a different OS. If you’re really trying to do this, it seems such a specific thing you’re trying to do that, again, I would recommend you contact Mathworks Tech Support if you can’t find help anywhere else on-line.

The command I provided above should work to put the path of the library your trying to use before Matlab’s libraries path (of course, your path won’t be /opt/local/lib/). You should also look into the loadlibrary command.

As of version 7.9 (aka R2009b), there is a new Tiff Class, which acts as a gateway to the LibTIFF libarary. I have that version, and just ran it and got this:

>> Tiff.getVersion()
ans =
LIBTIFF, Version 3.7.1
Copyright (c) 1988-1996 Sam Leffler
Copyright (c) 1991-1996 Silicon Graphics, Inc.

Version 3.7.1 came out in… *gulps* 2004!!

I tried to load a newer version (I’m on a Mac, so am using the latest from MacPorts) using the loadlibrary command, but ran into 64-bit problems. Hope this info helps you somewhat. If you get really stuck, I’d contact Mathworks support.

Does it have to be windows compiled libtiff or can I also use linux compiled libtiff, ie DLL or .so file ? Can someone PROFICIENT with this procedure test a version and post instructions that actually work as well as some debugging information ? If libtiff has dependencies, how to debug them or discover them from error messages ?

Thanks to the star who can help
