From the previous discussion, I remember that we (or rather mww)
started by changing the +universal variant to build all 4 versions (2
architectures each of 32-bit and 64-bit) but this was problematic
because many ports failed to build out of the box as 64-bit, and
there
was no clear upgrade path for those who already had 2-architecture
universal variants installed, and it was said that 64-bit versions of
most ports don't make sense anyway (aren't faster, or possibly are
even slower). But it seems like we want to be able to do this for
selected ports.
Most of the ports that failed were using Carbon, or otherwise old...
(old Carbon GUI does not support 64-bit, only Cocoa GUI does that)
Thanks for revisiting this. There is a real need to be able to
compile, by default, for the native architecture of your machine.
There is also a real need to preseve backwards compatibility. A
modest proposal (based on posts and discussions old and new) that
might please everyone:
* Keep the "universal" variant for building architecture-fat binaries
(only).
* Add a new "fat" variant for building bit-fat binaries (only).
* Activate the "fat" variant by default on all library-class ports.
* Add an config option to set the default bit-ness ("always 32-bit"
or "native") for all builds.
Some of it may well be in there already; I haven't been able to
locate it in the docs though, e.g. where does "universal_archs"
apply...?
I reverted +universal back to meaning "10.4u SDK for ppc/i386 arch",
and then made them into parameters for overriding locally if desired.
So is it possible, using the current MacPorts 1.6.0, to build bit-fat/
quad-fat binaries, and if so, how is this accomplished (feel free to
bring this onto the users-list)?
thx,
/Emil
