Hi Waleed,
thanks for that. To be fair to the guys at trolltech, the comments
were mostly useful but a bit of annoyance crept in. It perhaps
comes across differently reading the bug from getting a (long) series
of individual mails.
But I had not realised that the old installed libs were the problem.
Meanwhile, for the full build I've been adding -system-ffmpeg
(except on the oldest system which had ffmpeg-3.2.something) and
also -webengine-icu. These seem to save a little space and time.
Unfortunately I don't have any time to spend on this at the moment.
