installation error using coinbrew

[FoHoOV]

I've followed the instructions of coinbrew on how to install packages, but it gives me this error while trying to build/install this package.
command I'm running:

bash

./coinbrew build

and then selecting 17 for this package (I've also installed gfortran-9 and used update-alternatives to map gfortran to gfortran-9 because that also gave build errors)

here is my current error output:

running like this did the job:
./coinbrew build Couenne ADD_CXXFLAGS=-std=c++11 --reconfigure

imma keep this issue open, maybe you want to do this automatically or add a warning.
