thank you again for your answer.

ok, well i think there's nothing more i can do about it then.

the strange thing is that googling for XRRFreeScreenResources and
mandriva gives only one russian and one turkish site... so not many
people seem to have encountered the problem. moreover the rest of qt4
(designer etc) seems to work perfectly.

:-)  - i wish i could...

my question was in fact more about rights and technics, not a complaint:
many programs come as rpm-like distribution packages, as source
packages, and as precompiled packages just zipped together that work
on many distributions. i just wondered why this doesn't exist for
maybe the special licences make it necessary to break it up in so many
subpackages? or the resulting tarball would be too big to be
distributed easily?
or is it really that usual eric users also know c compiling, package
dependency stuff and shell variable tweaking well and there is no use
for a fool proof distribution? it's quite possible.

don't get me wrong: i completely understand that developers are not
always interested in (or free for) easy distribution of their work.

well, i hoped to get the qt4 version going. - i just love programming
in python and qt but maybe eric and all that is just for people who
know more than me  :-(

thanks again for the quick answers


ps: after all that trying even my eric3 is no longer working :-)  -
the night is young...
