nextstep/INSTALL: universal binaries

[Glenn Morris]

Hi Jan,

nextstep/INSTALL has a section on universal binaries.
Maybe this needs updating/removing, given that ppc is no longer supported?

TIA.

Make sense, section removed.

Does that also imply that 32 bit OS X is not supported any longer,
only 64 bit? (I hadn't been paying attention, I have only 64 bit
capable hardware.)

I presume then that universal binaries aren't ever used for combo
32bit and 64bit executable bundles? (I honestly don't know, I've
never paid attention.)

Yes, you can have all the different arches in a universal binary (ppc,
ppc64, i386, x86_64). As far as I can know you can't have 2 of the same
arch in there though.

I don't understand those removed nextstep/INSTALL instructions though.
How did CFLAGS+="-arch ppc -arch i386" work in terms of unexec?

I think you can make that, but the documentation removed only talked about ppc + i386.
We never mentioned any other variant.

Yes, you can do that.  For a distributable binary, it seems like a waste of space and bandwidth, though, as the 64bit version is not that much more performant, and the 32bit version is only required by a small minority of users.

I have stopped distributing the 32bit+PPC universal builds (for new versions) about a year ago, and switched to 64bit binaries only.  Users can compile it themselves if need be.
This was done based on analysis of actual Aquamacs usage data, where the need for 32bit (and also PCC) was minuscule, and had been for quite a long time.

This applies to Mac hardware only.
