What steps will reproduce the problem? x=randn(100,20); y=randn(100,1); fit=glmnet(x,y); What is the expected output? What do you see instead? it shoudl return a struct. Instead it returns

x=randn(100,20); y=randn(100,1); fit=glmnet(x,y); ??? Invalid MEX-file '/Users/kpmurphy/pmtksupport/glmnet-matlab/glmnetMex.mexmaci64': dlopen(/Users/kpmurphy/pmtksupport/glmnet-matlab/glmnetMex.mexmaci64, 1): Library not loaded: /usr/local/lib/libgfortran.2.dylib Referenced from: /Users/kpmurphy/pmtksupport/glmnet-matlab/glmnetMex.mexmaci64 Reason: image not found.

I have the same issue, has anyone found a solution?

Apparently this library /usr/local/lib/libgfortran.2.dylib is misplaced. Creating a symbolic link to the file in /usr/local/lib/ solved this issue for me. In my case, this library was available through an R install: /Library/Frameworks/R.framework/Versions/Current/Resources/lib/libgfortran.2.dylib

I am running 64 bit Mac OSX 10.7.5 and Matlab 2012a. initPmtk3 is crashing on me at the glmnetMex line 254. No message is provided, Matlab just dissappears. I added a symbolic link as instructed to the same R.framework library described above so I now have an entry for libgfortran.2.dylib in /usr/local/lib. However I still get the same crash. Any ideas.

It took me installing a symlink to /Library/Frameworks/R.framework/Versions/3.0/Resources/lib/libgfortran.2.dylib in the matlab directory that contains the libgfortran.3.dylib, i.e., /Applications/MATLAB_R2012b.app/sys/os/maci64/ . Finally glmnet runs. Haven't done extensive testing of features though.
