qreal is a typedef for float on arm platforms. I think this is an upstream bug, could you report it there please?
Comment 5 Davide Pesavento (RETIRED) gentoo-dev 2012-03-31 13:28:28 UTC 
It should build with USE=-c++0x anyway...
Comment 6 Davide Pesavento (RETIRED) gentoo-dev 2012-05-22 22:11:18 UTC 
Does 4.8.2 still fail?
Comment 7 Denis I. Polukarov 2012-05-24 09:46:04 UTC 
With masked c++0x & gcc-4.6.3 - success.

Do you mean with USE=c++0x enabled?

built with gcc-4.6.3

You haven't enabled the c++0x use flag. Your comment is irrelevant to this bug

(-c++0x) means that you have c++0x USE flag disabled and masked, so this is totally irrelevant for this bug report, which is about building qt-gui with c++0x *enabled*.

You have to unmask the flag locally and rebuild qt-gui.
Comment 12 Davide Pesavento (RETIRED) gentoo-dev 2012-12-27 09:07:19 UTC 
Can you try with qt 4.8.4 (which has USE=c++0x unmasked) please?

Not reproduceable with recent in-tree Qt and GCC versions. Feel free to reopen if issue still happens.
