Previous versions of FLTK tried to avoid generating a dependence on libstdc++ because C++ on Linux was notoriously unportable (thanks to GCC changing the name mangling algorithm so many times and the libstdc++ folks making so many ABI changes as well...) FLTK 1.1.9 shouldn't have this particular hack, so g++ should be used automatically. > # > ( echo ':g/^.SILENT/s//#.SILENT/g'; \ > echo ':g/^CXX.*gcc$/s//CXX=g++/g'; \ > echo :wq ) | ex makeinclude > > # DO THE BUILD > make > ---- snip > > I believe the correct Apple terminology for these 'fat' binaries > are "universal binaries". > > BTW, I think the OP mentioned building universal bins on a PPC platform. > I'm not sure, but I *think* some optional package needed to be installed > to get PPC machines to build for intel; I have some hazy recollection > Mike posted some details.

For 10.4 you need to use the "10.4 universal SDK" - see Greg's previous post for those options. -- ______________________________________________________________________ Michael Sweet, Easy Software Products mike at easysw dot com _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
