I wonder what the road map for SC is for the future as far as building it on MacOS Sierra with Xcode 8? the brew qt55 does not appear to be supported and brew qt5 which loads Qt5.7.1 does not have support for the Qtwebkit which is replaced by Qtwebengine. I believe qt55 will transfer to sierra if installed on El Capitan and then passed via a system upgrade but I haven’t tried that, and it will not be a possibility as new mac machines are released with Sierra installed already.

Is it not possible to install qt55 via Homebrew on Sierra? I updated yesterday, I'll try tonight.

On my system - Sierra upgraded from El Capitan, Xcode 8 - it is possible to install qt 5.5.1. Elder versions of Qt are still accessible via special links (maybe homebrew-versions?) I forgot the exact link, but recent brew will find the link for you by scanning taps if you type brew install qt55. When building SC you should point CMAKE_PREFIX_PATH to /usr/local/opt/qt55. Oh, I just experience, that qt55 on Sierra is compiled locally if you install it from scratch.

@rbnpi, you are right, there are problems: Homebrew/homebrew-versions#1399
My build failed, I hope the workarounds presented in above issue work...
Midterm we will need to switch to wegengine...

Damn, the workaround is to install “Qt Companies” Qt, I don’t like that...

@bagong Yes I tried again and it gave the same issues. At present I am using the SC3.8.0 beta 1 binary and that is working fine, but for the future I think a switch to webengine is the answer. I note that Xcode has just gone to 8.1 but I think that is just to accommodate the new touch bar Apple announced yesterday, so I don’t think an upgrade will help.

@rbnpi Yes, we need to switch to webengine, there is even a sketch as PR. The problem are two: 1) find people that work out the details and 2) deal with the problem that while OSX and Windows require/would do better with Qt 5.6 or higher some Linux platforms haven’t even arrived at 5.5 (I think Debian stable, which was at Qt5.3 last time I checked a few months ago).

So a warning for OSX users, confirming @rbnpi: you cannot install a fresh Qt5.5 on Sierra atm, you can only continue to use the one remaining from an el-capitan install. All currently suggested workarounds fail (including using vanilla qt company Qt 5.5, where the SC build fails with an rpath error)
