Yes, at least in theory. The oldest I know of currently is 10.5 PPC 32-bit. There is legacy code in the Portfile that might allow it to work with 10.4, but I do not have a way to test this and also have heard nothing from that group of users (assuming there are any out there) as to whether this updated port works for them. I do know that 10.5 PPC 32-bit takes "a day" to compile. On my 2.6 GHz Core-2 64-bit, and no special variants, I can get the compile time down to "only" 1.5 hours. The compile is highly parallelizable, so in theory an 8-core modern Intel processor could do this compile in maybe 30-45 minute. Compile time doubles with +debug, and also with +universal -- so a +debug+universal will take my computer around 7 hours. > Are there any major gotchas with, say 10.5 on 32 bit Intel? We fixed a bug last week that seems to allow qt4-mac 4.8.2 to work on 32-bit Intel and PPC under 10.5 (and, newer, for x86). As far as I know, this latest Qt works just fine on 10.5 PPC or x86 32-bit. I've tested this release on 64-bit Intel 10.6 and 10.7. I'm in the process of fixing an issue with ccache, but that won't effect Qt runtime. > Is there any word on Mountain Lion support with 4.8.2? Just works? Hopefully it "just works", but I won't know until I get access to 10.8 or Qt publishes something (which they might have already, and I just haven't seen it). I've read nothing online about Qt and 10.8, but then I haven't been actively looking either. Hope this helps! - MLD _______________________________________________ macports-dev mailing list [email protected] http://lists.macosforge.org/mailman/listinfo.cgi/macports-dev
