[gentoo-user] qtiplot

[brullo nulla]

Hi,

I have an x86 gentoo system, and I would like to install qtiplot.
Unfortunately:
- qtiplot 0.8.x requires qwt-4. I have both qwt-4 and qwt-5 installed,
and when compilng qtiplot seems to pick invariably the qwt-5. How do I
force qtiplot to build with qwt-4 ?

- qtiplot 0.9.x requires to unmask dependencies like split ebuilds for
qt-4.4.2 and boost-1.35. Is it safe to do so in a mostly x86 stable
system? What caveats could there be in migrating to the qt-4 unstable
split ebuilds?

Thanks,
m.

Wild guesses, semi-tested on amd64 only:

- in the current qtiplot-0.8.5-qmake.patch replace "-lqwt" with "-l:libqwt.so.4"
- check that you have qt:3 built with USE="opengl"
(- gcc-4.3 patching, which were a sort of a detour since I just didn't
want to downgrade gcc in the chroot in which I made my testing in)

After that I got qtiplot-0.8.5 emerged in a simplistic chrooted amd64
environment, which had little more than the basic qt stuff and
explicitly emerged qwt 4 and 5:

 x11-libs/qwt
    selected: 4.2.0-r3 5.0.2-r1

However, I don't know this piece of software and I don't think I'm
going to learn it right now, so that's as far as I planned on
"testing" it right now. :)

Maybe you would like to file a bug in b.g.o? I can dump my crude,
couple-line patches/changes there and whoever needs/maintains qtiplot
can then refine them or reject them as needed.

Thanks for your wonderful reply! However it seems a bit of work. Nothing
fancy:but if I have to spend some time patching and testing, I'm rather
doing it for the latest version (0.9.x)

I keep your mail close, in the meaning that if 0.9.x refuses to work,
I'll fallback on 0.8.5 with your suggestions. But if anyone has
suggestions on the qt stuff, before b0rking my laptop, I'd be happy.
