And where is your "libtqt-mt.so.3" located ?
Isn't TQT3
supposed to be installed in /usr ? So that libraries are under /usr/lib64
directly ... that's what I do and it works very well ...
I install TQt3 to a $PREFIX of /opt/trinity. qmake, moc, uic, etc. all are installed in
/opt/trinity/bin.
After TQt3 is installed, $QTDIR then is set to /opt/trinity as well.
Using this method I don't have to install TQt3 to any weird subdirectories as was the
past practice with Qt3.
In 32-bit I have no trouble building any Trinity package.
In 64-bit I have no trouble building any Trinity package except tqca, tqca-tls, python-tqt
and python-trinity.
For 32-bit builds libtqt-mt.so.3 is installed in /opt/trinity/lib.
For 64-bit builds libtqt-mt.so.3 is installed in /opt/trinity/lib64.
The configure process does not have a problem finding $PREFIX, $QTDIR because I explicitly
declare those variables.
The only problem with building tqca and tqca-tls is when $LIBDIR changes from $PREFIX/lib
to $PREFIX/lib64.
If TQT3 is in non-standard prefix (ex: /opt/trinity),
you
can modify the "configure" script a bit more than I did.
Look at the line "for p in /usr/lib64/tqt /usr/lib/tqt ...". These are
all the path where we look for TQT3 libraries.
Just add the path you want, like ${PREFIX}/lib64 and
${PREFIX}/lib at the beginning the path list, and it should do the trick.
Adding ${PREFIX}/lib64 does not help because the configuration process finds $PREFIX and
$QTDIR. I explicitly define those variables in my build script. The problem is not finding
$PREFIX/lib64 ($QTDIR/lib64).
If you have too much trouble with this
"configure" script,
you can stop using it and build tqca directly with only 3 commands !
(just check that the "qmake" command is in your PATH ...)
export QTDIR=/opt/trinity
qmake qca.pro
make
OK. I tried that. I can't get that to work either. Here is the build output:
===========================================================
g++ -c -pipe -g -fvisibility=hidden -fvisibility-inlines-hidden -Wall -W -O2 -D_REENTRANT

/usr/lib64/gcc/x86_64-slackware-linux/4.5.2/../../../../x86_64-slackware-linux/bin/ld:
cannot find -ltqt-mt
===========================================================
The output shows that /opt/trinity/lib is being used rather than /opt/trinity/lib64.
I can run this process manually and manually edit Makefile to /opt/trinity/lib64. Then
make runs without error.
The trick is to force tqca to look in /opt/trinity/lib64 and not in /opt/trinity/lib.
