As a user, I don't want to spend twice the compilation time for every package and use twice the disk space for the executables and libraries. In my opinion, universal binaries are an invention for distributors of precompiled binaries, not for users. As for the distribution of precompiled binaries, Fink has, in principle, the tools for providing the same (or more, because of smaller downloads) comfort as what is achieved by universal binaries, namely separate binaries for ppc and intel, with automagic choice of the right architecture at download time. The only problem is that there is no central Fink bindist any more... -- Martin - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Fink-devel] An option to build universal binaries ?
(..) Not to burst your bubble, but I've thought about this a lot (and built probably 40 individual KDE dependencies as universal packages manually) and it's just not feasible.

That will work for basically nothing in Fink. If it were that easy, we would already have done it. :) Autotools-based packages (probably 80% of the stuff in fink) will need at least --disable-dependency-tracking passed on the configure line as well as the -arch stuff in your flags. That will work for maybe 60-80% of autotools (that's 60-80% of 80%). And, only if you're on Intel, because on PowerPC you'll also need - -isysroot /Developer/SDKs/MacOSX10.4u.sdk which also adds flags which piss off some custom-written autotools stuff. Probably another 20-30% of *those* (including most network tools) do endianness checks at configure time, which means that it will build on all platforms, but create broken binaries on whichever platform you're not building on. So that's 70-80% working in the 60-80% of 80%. ;) Non-autotools-based packages are completely a crapshoot; most of the manual build system stuff that isn't autotools does not care what's in CFLAGS, or treats it differently. Yes, it is theoretically possible to get everything in Fink to build universal. In practice, it would require tons and tons of hand-hacking by maintainers, as well as infrastructural support in Fink, and neither side has the manpower for us to reasonably expect it to happen.

[Fink-devel] An option to build universal binaries ?
Hi, I would like to know if it would be possible to use fink to build a whole universal binary hierarchy under /sw ? the idea is to have a shared directory using nfs for ppc and x86 so if it exists an option to add to fink.conf, that would be nice to let me know Regards, Djamé - This SF.net email is sponsored by: Microsoft Defy all challenges.

To do a cross-compile for PowerPC on an Intel box would require removing _every_ Intel binary library from the Fink tree, and then rebuilding every package for PowerPC. Not to mention that the low level binary package handler, dpkg, is only capable of coping with a single architecture. Maybe one could use a PowerPC and an Intel box, install identical package sets, and then manually generate universal binaries from the two fink trees. -- Alexander K.
