Cannot run inversions in Matlab

Chao_Jiang

Hi, I found I cannot run the inversions in Matlab and the error is:

I think I have successfully installed the source code on my Macbook Pro M2 chip and got 'ISSM development path correctly loaded' when starting Matlab.

Thanks,
Chao

Hi Chao,
We have been seeing this problem a lot lately with the newer versions of GCC on macOS. I am going to work ASAP on changing our build system to avoid this, but for now, what you can do is, find the path on your machine to libgfortran, then do,

sudo ln -s <path>/libgfortran.5.dylib /usr/local/lib/libgfortran.5.dylib

You will likely need to do the same for libquadmath.

Hello Chao

hum... it looks like you have a problem with a fortran library... do you know where libgfortran.5.dylib is on your computer? (in case that helps, this is the path on my machine /usr/local/gfortran/lib/libgfortran.5.dylib). Once you find it, could you try to configure ISSM again by adding this line to your configure.sh script:

--with-fortran-lib="-L/usr/local/gfortran/lib/ -lgfortran" \

(adjust the path according to what you find out) and the recompile:

./configure.sh
make install

Let us know if it still does not work!

Hi Mathieu,

Thanks for your fast reply.

I checked my libgfortran.5.dylib location using locate libgfortran.5.dylib and it returns three directories that contain this file:

I had the line --with-fortran-lib="-L/usr/local/gfortran/lib/ -lgfortran" \ in my configure.sh script and recompiled but Matlab still cannot work. Is this related to that I have three libgfortran.5.dylib path?

Thanks,
Chao

Hi Justin,

Thanks for your prompt reply!

I checked my libgfortran.5.dylib path and find there are three paths contain this file:

and one is the /usr/local/gfortran/lib
what can I do in the next step?

Thanks,
Chao

Try,

sudo ln -s /usr/local/gfortran/lib/libgfortran.5.dylib /usr/local/lib/libgfortran.5.dylib

then run ISSM in MATLAB again. You will probably get a similar error about libquadmath and will have to do the same as above for it.

Thanks Justin! Matlab works now! Much appreciate your time. Chao
