Qt5 dosn't build --with-d-bus about homebrew-core

[tdsmith]

Why did you flag that error?

The more interesting error is:

I see:

tim@rocketman:~$ mdfind -name ft2build.h

/usr/local/Cellar/freetype/2.6.3/include/freetype2/ft2build.h

Why does it want Freetype?

@yurikoles The errors you cited don't show up in the log files in your Gist. Where are they from?

Why does it want Freetype?

@tdsmith That's just a dependency of Qt 5, albeit one that is vendored by Qt, thus it should be using qtbase/src/3rdparty/freetype/include/ft2build.h from the Qt 5.6.0 tarball. However, it seems to auto-detect a system FreeType (not sure which one this is supposed to be), as can be seen from the FreeType ............... yes (system library) line in the 01.configure log file.

@UniqMartin but I see them

[UniqMartin]

@yurikoles I have made some changes to the qt5 formula that should fix your build failure. Can you please run brew update, re-try brew install qt5 --with-d-bus, and then report back? Thanks!

By the way, I have found the errors you quoted in your original comment in the 01.configure log file. Those are not fatal and not the reason why your build fails. That's just the configurescript of Qt 5 trying to detect what is available on your system and what not.

[yurikoles]

Thanks, seems like fixed.
