It would be nice if the version of required Qt is specified

[sa2ajj]

For both Ubuntu and Fedora only package names are listed, however the things are a bit different from a release to release.

So I'd suggest that the required version of Qt is explicit as well as for what version of Ubuntu and Fedora the instructions work.

Fedora never shipped an incompatible Qt5 version, so no.

[sa2ajj]

Incompatible in what sense?

Qt5 can refer to a range of different versions and there're subtle differences in functionality and in packaging (I can't really talk for Fedora, while I have certain experience w/ Ubuntu and Debian).

[KAMiKAZOW]

Qt5 versions so old that Sigram does not run on them were never shipped by Fedora. Not only that but over the course of Fedora 20's release cycle (F19 did not include Qt5) there were several new Qt5 versions shipped as update.
Therefore requiring a specific Qt5 version makes zero sense under Fedora.

[sa2ajj]

Maybe for Fedora.

For Debian/testing I had to modify the package list:

sudo apt-get install g++ gcc qtbase5-dev libqt5sql5-sqlite libqt5multimediaquick-p5 libqt5multimedia5-plugins libqt5multimedia5 libqt5qml5 qml-module-qtgraphicaleffects qml-module-qtquick-controls qtdeclarative5-dev libqt5quick5

Hi...
Because of 2 below reasons:

1. We ship Qt5 with packages because of compability on many distros. Many distros don't support Qt5.2 yet.
2. I know it's bad. But currently We haven't enough person in our team to make packages for all distros and for all of Sialan projects. I hope we can solve this problem in the future.

@realbardia you mention Qt5.2 here, and that the main point of my ticket: please include this information in the README file.
