Library error with Mac binary El Capitan

ryanwalker

After installing the new binary (on Mac 10.11.5) I get this error in Matlab:

Invalid MEX-file '/Users/rtwalker/ISSM/trunk/lib/IssmConfig.mexmaci64':

dlopen(/Users/rtwalker/ISSM/trunk/lib/IssmConfig.mexmaci64, 6): Symbol not found: _mexCallMATLABWithObject

Referenced from: /Users/rtwalker/ISSM/trunk/lib/IssmConfig.mexmaci64

Expected in: /Applications/MATLAB_R2014a.app/bin/maci64/libmex.dylib

in /Users/rtwalker/ISSM/trunk/lib/IssmConfig.mexmaci64

I suspect this is related to some earlier errors where Matlab looks for libraries in the wrong place, but I could definitely use help on this one.

Thanks,

Ryan

Hi Ryan,

what version of MATLAB are you using? I think that MATLAB changed its mex compiler in 2014 or 2015. If you are using an old version of MATLAB, you might want to upgrade.

Let me know if you have any other question

Hello Ryan,

I think this might have something to do with your Matlab version. Can you check whether the missing symbol exists in:


/Applications/MATLAB_R2014a.app/bin/maci64/libmex.dylib

If the symbol is there, then would you:


ldd $ISSM_DIR/lib/IssmConfig.mexmaci64

I don't have that symbol in libmex.dylib, just _mexCallMATLAB and _mexCallMATLABWithTrap.

I'll check availability of a Matlab upgrade.

Thanks,

Ryan

OK, Matlab 2015a avoids this problem.

Thanks,

Ryan
