Compilation errors

[Jerther]

Compilation seems to depends on qt-devel actually, and also on g++ (gcc-c++) but then compilation fails:

My output from qmake --version is the following:

QMake version 3.1
Using Qt version 5.8.0 in /home/francois/Settings/Qt/5.8/gcc_64/lib

So no qt-dev... I've shown you mine, now show me yours! :P

[Jerther]

[jerther@localhost LibreBridge]$ qmake-qt4 --version
QMake version 2.01a
Using Qt version 4.8.7 in /usr/lib64

Using Fedora 25 btw. Hmm, looks like Fedora's package is outdated. Which distro are you using?

[juef17]

Linux Lite 3.4, but I installed that Qt version manually, I'm not sure which Qt package is available for it. I will update the build instructions with this info!

Okay so I did install qt5-devel instead of qt-devel. Still getting the same error:

[jerther@localhost LibreBridge]$ qmake-qt5

Should I try an even more recent version of qmake?

Try adding #include <random> with the other includes in Game.cpp.

I'm on an earlier version of g++ (5.4.0) but I doubt that's the problem.
