I need to deploy a small app that targets OS X 10.5 and up.
I am on a 10.7 system, with XCode 4.2
I need to target x86 in order to support 10.5. I can do universal binaries to support x86_64 as well, but that's not strictly necessary. I'd prefer Cocoa over Carbon (just because it's new), but no strong preference there either.
I've read http://qt-project.org/doc/qt-4.8/developing-on-mac.html, in particular:
bq. There are two versions of the Qt binary, one with x86 and x86_64 Cocoa and another with x86 and ppc Carbon. If you want a different setup you must build Qt yourself using the source package. To explicitly configure Qt to build for 34-bit or 64-bit architectures (or both), use the -arch flags (see Universal Binaries). For the Cocoa version, 64 bit is chosen by default.
However, I have not been able to find universal binaries for download on the site? All the downloads offered on http://qt.nokia.com/downloads only provide x86_64 (QtSDK, or the Qt Libraries). This all seems in direct contradiction with what's stated on http://qt-project.org/doc/qt-4.8/developing-on-mac.html
I hope I've missed something. Otherwise, what's my best option:
- Go back to Qt 4.6.4 linked on http://qt.nokia.com/downloads. I did confirm that those are universal binaries, but I can't use Qt Creator with it, and I need to install an older XCode apparently (3.2).
- Try to compile Universal Binaries for 4.8 myself. Probably not worth the trouble.
