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

read this link, it explains how to configure matlab on some linux systems.

here the steps that are relevant to you:

To enable running external programs, […] fortran libraries need to be properly updated and linked. Look at the output of this command:

ll "$MATLABDIR/bin/glnxa64/"

It is likely that [this link] exist:

libgfortran.so.3 -> libgfortran.so.3.0.0

Search for [this library] on your machine:

locate libgfortran.so

[…] Update Matlab's links to point to these newer versions:

sudo ln -sf [location of libgfortran.so.3.0.0] "$MATLABDIR/bin/glnxa64/libgfortran.so.3"
