Description Paul Eggleton 2011-12-07 06:32:43 UTC 
Configuration on the autobuilder has been changed recently so that builds are done in a different order. From the logs at least it appears that the Qt3 build is attempting to use Qt3Support headers from Qt4, which it should not be doing:

http://autobuilder.yoctoproject.org:8010/builders/nightly-arm/builds/206/steps/shell_67/logs/stdio

It should be possible to build these independently in any order as long as include and library paths are correct.
Comment 1 Paul Eggleton 2011-12-08 08:44:09 UTC 
I've reproduced this locally - you have to do the following:

1. bitbake qt-x11-free-native
2. bitbake qt4-native
3. bitbake qt-x11-free

The issue is conflicting moc/uic executables in the sysroot between Qt3 and Qt4, so that incorrect includes get added to the source files that these tools create. uic*/moc need to be moved/renamed so that they can coexist and yet apps can still find the right one.
Comment 2 Paul Eggleton 2011-12-08 11:58:09 UTC 
Have posted a fix for this to the yocto mailing list.
Comment 3 Paul Eggleton 2011-12-09 08:36:28 UTC 
Fix has been merged into meta-qt3 (commit id 016ed1af2a0986cd90bdd073091537d954588813).
Comment 4 Yi Zhao 2011-12-15 23:17:20 UTC 
Verified with 1.2 M1 RC2 20111213 build.
