libgfortran: version `GFORTRAN_1.4' not found

Question

I am getting the following error when I trying to a run mex file in MATLAB:

??? Invalid MEX-file
\'findimps3.mexa64\':
/MATLAB/bin/glnxa64/../../sys/os/glnxa         


        

Answer 1

In my case the following command worked:

sudo ln -sf /usr/lib/gcc/i686-linux-gnu/4.7/libgfortran.so /usr/local/MATLAB/R2012a/sys/os/glnx86/libgfortran.so.3

Matlab was complaining it couldn't find the GFORTRAN1.4 in the following location:

/usr/lib/gcc/i686-linux-gnu/4.7/libgfortran.so

So I linked this location to the library I had :

/usr/local/MATLAB/R2012a/sys/os/glnx86/libgfortran.so.3

I found the location of this library by using the locate command as given above:) Thanks for the help:)
