One way would be to set up local package descriptions which build as 32-bit rather than 64-bit, e.g. via flags given to the compilers, and have them install in a private directory. For example, see the existing 32bit packages for 10.7-10.8: $ dpkg -L libpng15-32bit-shlibs /. /sw /sw/lib /sw/lib/i386 /sw/lib/i386/libpng15.15.dylib /sw/share /sw/share/doc /sw/share/doc/libpng15-32bit-shlibs /sw/share/doc/libpng15-32bit-shlibs/ANNOUNCE /sw/share/doc/libpng15-32bit-shlibs/CHANGES /sw/share/doc/libpng15-32bit-shlibs/INSTALL /sw/share/doc/libpng15-32bit-shlibs/LICENSE /sw/share/doc/libpng15-32bit-shlibs/README /sw/share/doc/libpng15-32bit-shlibs/TODO where the library gets installed in /sw/lib/i386 to avoid collisions with the regular libpng15. One nice thing about this method is that it should work the same way on anybody's 10.7 or 10.8 system, so help with details will be easy to get. Doing a 32bit Fink on 10.5 or 10.6 in VirtualBox has a couple of pitfalls: 1) Even getting your 10.5 or 10.6 to work. 2) Speculative: some libraries may not actually be forward compatible. but that's more or less like having an additional system where Fink will do 32-bit builds. To build universal binaries would require extensive hacking of the Fink build process. -- Alexander Hansen, Ph.D. Fink User Liaison My package updates: http://finkakh.wordpress.com/ ------------------------------------------------------------------------------ Everyone hates slow websites.
