[gentoo-user] qt3/4 confusion
hey, I am trying to compile a program written in qt3 which apprently, according to the author, fails because it being compiled using version 4 qmake. I checked and indeed qmake is from version 4, yet in my environment, the QTDIR variable is pointing to /usr/qt/3. Now that both confuses me and leaves me with the question on how to change the profile completely to qt3 for this compiliation. Has anyone a hint for me? thanks, KArstn -- gentoo-user@gentoo.org mailing list

I am using a little shell function to change between various Qt
versions (put it into ~/.bashrc if you like). I'm quite sure the
library line is not necessary, but it doesn't hurt either and I kept
it.
switchqt()
{
export QTDIR=$1
export PATH=$QTDIR/bin:$PATH
export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
}
switchqt /usr/qt/3 activates Qt 3 for this shell.

Re: [gentoo-user] qt3/4 confusion
hey alex,
I used your instructions, and got a bit further yet there are still
issues that seem to be contradictory. First of all, a snippet from the/
./configure /process:
/
checking whether QTDIR environment variable is set... /usr/qt/3
checking for Qt library... qt-mt
checking for Qt library version = 3.1.1... yes
checking for qmake... /usr/bin/qmake /but it looks in /usr/bin ??
that is certainly part of the problem, since the version there is from
qt4 (/qmake --version -- 4.1.3/)
so this part of the make process certainly make more sense in that light:
/g++ -c -pipe -O2 -mtune=i686 -pipe -D_REENTRANT -Wall -W -fPIC
-DQT_NO_DEBUG -D
QT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++
-I. -I/u
sr/include/qt4/QtCore -I/usr/include/qt4/QtGui -I/usr/include/qt4 -I.moc
-I.ui -
o initfio.o initfio.cpp
/
so it basically includes qt4, which must lead to failure. The qmake from
/usr/qt/3/bin returns to be, obviously, version 3. something is strange
there, any idea?
thanks,
Karsten

Has anyone a hint for me? thanks, KArstn here is a quick and very dirty workaround. quickpackage qt4, unmerge qt4, install your app, emerge qt4 with usepkg -- gentoo-user@gentoo.org mailing list
