This one needs kicking upstream. I can't find any fix or bug report on the upstream trackers.

[jakepetroules]

As per QTBUG-48079, only security-related patched will be added to Qt 4.8 from this point forward. Please deprecate the Qt 4 formula and encourage users to use qt5 instead.

[MikeMcQuaid]

@jakepetroules When all software using Qt4 is ported to Qt5: sure.

[jakepetroules]

Deprecation tends to encourage that. ;)

[DomT4]

I'm pretty strongly considering marking Qt4 as "will not build" on 10.11 and above, but I'm not sold on the idea that upstreams are going to rush to switch over to Qt5 if they haven't already at this point.

[MikeMcQuaid]

@jakepetroules I don't think that's our job.

[timblechmann]

@jakepetroules you know that huge parts of kde are still based on qt4?

@MikeMcQuaid, if upstream refuses to fix this issue, homebrew might patch qt4 to forward-declare the removed functions as they will most likely still be in the binaries, but were only removed from the headers

Yeh, we'll need to work something out.

[DomT4]

Should be fixed by Mike inserting the backport that was floating around.

Confirmed: brew install --build-from-source qt now works on my OS X 10.11 GM seed / Xcode 7 GM seed test box.
