Error building 4.8.0 from source on Mac OSX Lion
-
OSX 10.7.3 with Xcode 4.2, trying to build Qt 4.8.0 from source using "./configure -arch x86" (I'm stuck in 32-bit because of QTKit/QuickTime APIs I need, and the pre-built Qt libs are 64-bit only). I also tried "./configure -arch x86 -arch x86_64" with the same result.
The build was going ok for quite some time (over an hour) but then failed at this point. It seems to be a problem linking "libqsqlmysql_debug.dylib" for i386, but I'm not exactly sure.
Any ideas? Should I update to XCode 4.3 (I've heard its very buggy)? Do I need more options in my Qt configure to get this to work? Thanks!

The error message is quite clear here: You're building Qt for (at least) i386 architecture, but the mysql libs are built for some different architecture(s) (probably x86_64). You need to either get mysql for the needed architecture, or build Qt for the architecture of your mysql installation.
