Hi all,

I just tried updating the interval package to version 3.1.0. However, I
got a build error while building crlibm:

The above option applies to llvm, not gcc. I’m not sure how to tweak
the Makefile.in to fix this.

I’m building against octave 4.2.1, built using gcc 7 under macOS High
Sierra (10.13.3 Beta), under MacPorts.

Hi Marius,

it has nothing to do with Makefile.in. This seems to be a problematic mkoctfile parameter that comes from Octave in this line:

https://sourceforge.net/p/octave/interval/ci/15d1a3142e16a25744a5dcfd3f750d8a53358cbd/tree/src/Makefile#l38

I am also not sure how to fix this.

Thanks for that clarification.

I’ve poked around and had mkoctfile print out the various variables, but could not find anything that would add "-std=c++11 -stdlib=libc++”. Indeed, running ‘strings /opt/local/bin/mkoctfile | grep stdlib’ came up empty.

Thus, this must come in from somewhere else.
