Mac OSX 10.10 - Compiling Qt 4.8.2
-
Trying to do a 32 bit compile with Qt 4.8.2 on OSX 10.10.2. I am trying the following configuration and it seems to go through, however when I do a "make" it fails within a 20 seconds or so. Is this because I am using 10.10? I can put an older version (i.e. 10.7) on my test machine to get this compiled. Any suggestions how to get these libraries compiled?
I just need a bare-bones install as I am using this for PyQt while only using QtGui and QtCore.
./configure -release -no-webkit -no-qt3support -opensource -nomake examples -nomake tests -arch x86

Hi,
For the Qt 4 series, you'll need at least Qt 4.8.6 starting from OS X 10.9
-
I build Qt4.8.6 on 10.10 with the latest Xcode and deploy back to 10.6. But I build the 64 bits, not 32 bits. Qt4.8.6 does need some patching to compile with a recent SDK and its QWidget UI does not look good on 10.10 (the usual misaligned text when there's a new OS X version, waiting for the final 4.8.7...).
Here's my steps:
https://dootaini.wordpress.com/2014/12/11/building-qt-4-8-6-x64-on-os-x-10-10-with-xcode-6-x-so-that-it-works-on-os-x-10-6/It should work the same with -arch x86 for a 32 bits build. If you really need 4.8.2, you will need to come up with your own patch file, still might gives you some inspiration.
For the Qt 4.x series it's "-sdk fullpath_to_sdk", like:
-sdk /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk
"-sdk macosx10.7" would be for Qt5. And if you are using a recent version of Xcode you are unlikely to have the 10.7 sdk.
