In src/Main/Makefile.am, OSG_LIBS is set explicitly to -losg, etc.
This is not portable with OS X, which uses "-framework osg" (it can
also use the -losg style depending on how osg was installed. End users
will use the -framework style installation).
The following patch demonstrates the problem, but it's not meant for
general consumption. It seems that what should be happening instead is
an autoconf check for the appropriate libraries. Autoconf is able to
find the right flags, whether they be -l or -framework. I'm not an
autoconf guru, but I think the magic command is AC_CHECK_LIB(osg,
<some symbol in libosg>) and so forth.
I'd be willing to write a patch adding AC_CHECK_LIB statements to
configure.ac, if someone more familiar with osg will point out a
symbol from each library (osgViewer osgGA osgText osgFX osgUtil osgDB
osgSim osg OpenThread), so I don't have to ingest the whole OSG API in
the process.
