This error has come up before a few times over the past couple years,

The "<built-in>" tag is coming from the gfortran compiler itself. I
suspect it is referring to built-in Fortran functions.

The control package is one of the few Octave Forge packages that has
Fortran source code that is compiled by the pkg command when installed.

Here are some references to threads and bug reports where this has come
up before, maybe this will help you resolve this or help users fix it
when it comes up again.


Thanks Mike; that's very helpful. It looks like not only is it only on macOS systems, but only with the Octave.app distribution. It sounds like our gfortran build has an issue. We are attempting to be conservative and build a Core2 gcc/gfortran by passing "-march=core2" to everything,
but maybe that's not working for gfortran.

sshah, can you try this:

Point Octave.app at your Homebrewed gfortran, instead of its own, and try installing control again:

setenv('F77', '/usr/local/bin/gfortran')
pkg install -forge control

If that still gives you an error, try locally rebuilding your Homebrewed gcc from source, and
use that:

In the shell:
$ brew reinstall -s gcc

In Octave.app:
setenv('F77', '/usr/local/bin/gfortran')
pkg install -forge control
