Re: [Boost-users] (was Re: 1.40.0 - 32_64 broken on OS X 10.6 Snow Leopard) (now ppc64 support removed with Xcode 3.2 on Snow Leopard.

I followed all tricks mentioned in this list or other forums (e.g. removing the -m64 option), but nothing worked for us. Building 32-Bit and 64-Bit at the same time seems to be broken. But I managed how to build a 4-way universal binary on Snow Leopard: just build every architecture separately and afterwards put everything together using the lipo tool. I wrote a blog article about how we build the 4-way universal binaries of Boost on Snow Leopard for our needs: http://www.mani.de/backstage/?p=324 Regards, Mani
