For me, getting the RPATH stuff was hard (since I didn't understand RPATH at all before this), finding a way to detect Qt4 so that it works for everybody was hard and doing the automoc stuff which KDE developers are used to was hard. Beside that, once I understood how generating sources during the build work, there where no big problems. Just a *lot* of work, where Laurent Montel did a huge job, I mean, we have millions lines of code. Said that, one year earlier this wouldn't have been possible, since at that time the then newly introduced non-recursive makefile generator still needed some time to mature. In the beginning there was basically nobody on my side, we started with scons. This didn't work out, so David (one of our core developers) gave me the "go" to try my luck with cmake. I did that and today I'm the buildsystem maintainer. Not sure I'm happy about this ;-) Bye Alex -- "Ein Herz für Kinder" - Ihre Spende hilft!
