Re: Problem compiling Octave on Mac OS X

[Bernard Desgraupes]

I have been building Octave from the HEAD sources (I mean the latest  
version in the Mercurial repository) recently and I also stumbled into  
this metis issue.
MacPorts uses the following trick to get around this:
post-patch {
    reinplace "s|-lcholmod|-lcholmod -lmetis|g" ${worksrcpath}/ 
configure
}


In other words they patch the configure script. As a result the  
Makefile contains the following declaration:
CHOLMOD_LIBS = -lcholmod -lmetis

The issue indeed is just that the metis library is not found at link  
time. Adding -lmetis solves the problem. I suggest the macro in the  
configuration phase checking for the presence of CHOLMOD be improved  
and include this -lmetis bit.

cheers

Bernard
