[gentoo-user] QT4 and QGLWidget
Hello,
I use Gentoo/LInux OS, with lastest Qt4.7.2 ebuilds,
and a Nvidia card or intel graphics (and mesa)
when I run qmlviewer with "opengl" params,
or I use QGLwidget viewport in my app,
I get this error:
"qmlviewer[6399]: segfault at 1763 ip b6a73630 sp bfa0ee00 error 4 in
libQtGui.so.4.7.4[b6887000+a1e000]"
I tried also to emerge last qt-*-4.7.999 builds, but no success.
glxgears works and glxinfo reports that I'm using direct rendering
no matter wich .QML I use.
also this one exists with error:
import QtQuick 1.0
Rectangle {
id: mainView
width: 1920
height: 1080
}
Ther's some missing use-flag maybe? Or is something broken on Gentoo
I think is something about gentoo, 'cause I tried to install last Ubuntu
11.04 and there my apps works nice
Thanks,
Lorenzo
Re: [gentoo-user] QT4 and QGLWidget
Hello, thank you for your reply, I check that I didn't mixed QT version, first I tried with 4.7.2, than I unmerged all qt packages and I tried 4.7.3 . every time after emerging I checked system consistency with revdep-rebuild. Now I unmerged all, emerged all QT packages (4.72) with "debug" use, but I haven't got any other message than: "qmlviewer[6399]: segfault at 1763 ip b6a73630 sp bfa0ee00 error 4 in libQtGui.so.4.7.2[b6887000+a1e000]" May I have to export some variables to have more debug info? Any other suggestion? Any hint I can try? In qt-mailing list they said that is for sure something about gentoo..

You said you're using 4.7.2 but this error says 4.7.4. Do you have mixed Qt versions around in your system somewhere? Maybe it's pulling in the wrong one.
Re: [gentoo-user] sys-fs/device-mapper
Hi
I don't think it's normal.
Maybe there is a loop in compiling.
Please check, if it's still running, if there is some piece of code that repeats
continuously.
Post your emerge --info output

All -
I am trying to emerge sys-fs/device-mapper on an older piece of
hardware (AMD Duron 800, with 512Mb of Ram). The package has been
compiling for something like 8 hours already. Is this normal? It
seems like an awfully long time to me. As a comparison, I was able to
compile the kernel in about 15 minutes. If this isn't normal, any
ideas as to what the problem could be. I didn't see anything on
bugs.gentoo.org.
Thanks,
James
