[MacPorts] #20739: Allow ports to indicate supported architectures
#20739: Allow ports to indicate supported architectures -------------------------------------+-------------------------------------- Reporter: ryandesign@… | Owner: macports-tickets@… Type: enhancement | Status: new Priority: Normal | Milestone: MacPorts Future Component: base | Version: 1.7.1 Keywords: | Port: -------------------------------------+-------------------------------------- Ports are assumed to be able to build on all architectures, but not all do. Those ports that don't need a way to indicate what architectures they do support. The muniversal variant has this, but we need it in MacPorts base, and it needs to be available all the time, not just in universal. For example, wine needs to be able to indicate that it supports the i386 arch only (not x86_64, not ppc or ppc64). -- Ticket URL: <http://trac.macports.org/ticket/20739> MacPorts <http://www.macports.org/> Ports system for Mac OS

By default, any arch is supported. A port like wine (which only works i386) would write "archs i386". A port like autoconf (which doesn't install any binaries) would write "archs noarch". A port like pango (which currently can't build 64-bit on Tiger) could write "platforms darwin 8 { archs i386 ppc }". "universal_variant no" should automatically happen if archs contains only one item. -- Ticket URL: <http://trac.macports.org/ticket/20739#comment:2> MacPorts <http://www.macports.org/> Ports system for Mac OS

It would have headed off the majority of these Snow Leopard issues before they even started. By default, I would like to see all dependencies built universally with the maximum amount of available architectures (including arm6/arm7 if applicable). This would allow for maximum flexibility -- if I want to install OpenCV, which links to Carbon and old Quicktime libraries and must be built in 32-bit mode, I still want the dependency libpng to be installed in the most flexible way. That way, later if I want to develop an iphone program that links to graphviz, which links to libpng, I'll be all set. It's really unfortunate that "port install foo" tries to only compile the default system architecture, and not something appropriate for foo. -- Ticket URL: <http://trac.macports.org/ticket/20739#comment:3> MacPorts <http://www.macports.org/> Ports system for Mac OS

As a MacPorts user (not developer), I think this is critical. It would have headed off the majority of these Snow Leopard issues before they even started. Unfortunately, nobody wrote any code to do this yet. By default, I would like to see all dependencies built universally with the maximum amount of available architectures (including arm6/arm7 if applicable). This would allow for maximum flexibility -- if I want to install OpenCV, which links to Carbon and old Quicktime libraries and must be built in 32-bit mode, I still want the dependency libpng to be installed in the most flexible way. That way, later if I want to develop an iphone program that links to graphviz, which links to libpng, I'll be all set.
It's really unfortunate that "port install foo" tries to only compile the default system architecture, and not something appropriate for foo. You can put "+universal" in your variants.conf if you want everything built universal. I suggested yesterday on the mailing list that we should do this by default on Snow Leopard. You can indicate what architectures you want in macports.conf. However, on Snow Leopard there's no point to specifying anything more than i386/x86_64, since Snow Leopard doesn't run on PowerPC.
I would expect nothing but problems by attempting to build ports for arm6, arm7, or any architecture other than i386/x86_64/ppc/ppc64 in MacPorts, so I would recommend not trying that. -- Ticket URL: <http://trac.macports.org/ticket/20739#comment:5> MacPorts <http://www.macports.org/> Ports system for Mac OS
