[16:17] <ennui> following the 'Building Unity 8' instructions, cmake fails at "find_package(Qt5Core 5.2 REQUIRED)", though libqt5core5a is installed. it's the exact same error that's described here: https://askubuntu.com/questions/625471/installing-dependencies-for-building-unity-8
[16:17] <ennui> any ideas?
[16:55] <JanC> ennui: not sure exactly what you need, but 'libqt5core5a' doesn't contain header files, which I assume cmake is looking for...
[17:06] <JanC> you probably need 'qtbase5-dev' & such
[17:08] <JanC> apt-cache showsrc unity8 | grep Build-Depends
[17:09] <JanC> or to install those dependencies, use: sudo apt-get build-dep unity8
[17:12] <JanC> (didn't try that, but it's what I would try :) )
[17:15] <ennui> JanC: thanks! 'sudo apt-get build-dep unity8' fixed the qt5core error, but I'm getting a bunch of other 'not found' errors. could you have a quick glance?

[17:17] <ennui> (I'm working with a fresh, up-to-date vivid install and precisely followed all steps in the build guide.)
[17:21] <JanC> to be clear: I've never built unity8, that was just general development info on Debian-based distros
[17:23] <JanC> I assume you are trying to build a current source version of unity8, which might have extra build-dependencies compared to the version in vivid
[17:23] <JanC> or newer versions of build-dependencies
[17:24] <JanC> maybe somebody else can help you with that
[17:24] <ennui> yes, I checked out the current trunk (as suggested). so there's no automatic way to figure out the build dependencies?
[17:25] <JanC> the main developers are more likely to be around during European (or maybe US) business hours on work days
[17:26] <ennui> JanC: okay, I'll ask again tomorrow, then. thank you!
[17:26] <JanC> ennui: the wily source package would probably have more up-to-date build-dependencies
[17:27] <JanC> ennui: see e.g. http://packages.ubuntu.com/source/wily/unity8
[17:27] <ennui> JanC: ah, perfect, thanks!
[17:29] <JanC> remember that it might not be possible to build a trunk version of unity8 on vivid without replacing a number of libraries with newer versions etc., which might break existing applications...
[17:31] <JanC> well, build deps won't break vivid, but libraries needed to run could break other apps
[17:32] <JanC> one way around this would be to create a wily chroot and work inside that
[20:38] <ennui> JanC: the unity build worked fine on wily. i'll file a bug about the outdated instructions.
