[Ifit-users] ifit: external programs and library errors

[farhi]

Hi Victor,

This issue is related to libraries shipped by MATLAB being older than
that of the system.
In your case this relates to LIBGCC_S. Other libraries may also be
concerned, e.g. LIBGFORTRAN.
I suggest an iterative solution.

REMOVE THE MATLAB LIBRARY
% sudo mv
/opt/MATLAB/MATLAB_Compiler_Runtime/v713/sys/os/glnxa64/libgcc_s.so.1
/opt/MATLAB/MATLAB_Compiler_Runtime/v713/sys/os/glnxa64/libgcc_s.so.1.org

then try again in case MATLAB would seek for the library from the
system.

IF THIS DOES NOT WORK, COPY THE SYSTEM LIBRARY IN PLACE OF THE MATLAB
ONE
% locate libgcc_s
/lib/x86_64-linux-gnu/libgcc_s.so.1
/usr/lib/gcc/x86_64-linux-gnu/4.8/libgcc_s.so
% sudo cp /lib/x86_64-linux-gnu/libgcc_s.so.1
/opt/MATLAB/MATLAB_Compiler_Runtime/v713/sys/os/glnxa64/libgcc_s.so.1

Tell me if this works.
Emmanuel.
