Issue in installing gfortran-4.3 about cutest

[nimgould]

Dear Sen

The issue is precisely as the error message suggests - Matlab R2017a needs gfortran 4.3 to build the Mex bridge from the fortran to Matlab, and other versions of gfortran are not compatible. I don't have access to an OSX machine, this side of CUTEst is taken care of by my colleague Dominique Orban who knows all about the tricky issues of homebrewing gcc/gfortran and OSX. Unfortunately as you are aware, Apple no longer supports gcc officially, and OSX users will always have to install an unofficial version, just as you have done. As far as I am aware, no verion of Matlab supports gfortran 10, Matlab is always a few years behind the state of the art. I am sorry but really I cannot help here, you will need a version of gfortran that is compatible with your version of Matlab.

Thanks Nick for quick reply. Finally I gave up using Matlab to interact with CUTEst. I'm now using Julia instead. I follow the instruction from https://abelsiqueira.github.io/blog/nlpmodelsjl-cutestjl-and-other-nonlinear-optimization-packages-on-julia/ and https://github.com/JuliaSmoothOptimizers/CUTEst.jl. It seems it now works fine.

In any case, thank you for the reply. Matlab is not very friendly to interact with other programs.
