./configure issue with qt

[dmkelly]

Hi all,
When I configure Showeq I keep running into this.

>> Found version.: 3.1.2
>>> Headers......: /root/qt-3.1.2/include/
>>>> Libraries...: /usr/lib/qt-3.1/lib/
>>>> Documentation...: /root/qt-3.1.2/doc/html/
configure: error: Something wicked happened while trying to validate your Qt installation!!! Please verify your libraries...

My qt lib is /root/qt-3.1.2/lib. I tried to redirect it with ---with-qt-lib=/root/qt-3.1.2/lib. But it wont take. Any ideas?
Thanks

Look in config.log and see exactly what happened. Do you have QTDIR set?

This is what I see in log file

QTDIR and LD_LIBRARY_PATH are set correctly in the enviroment, checked using
export -p.

Is there a libqt-mt.so link somewhere in your qt install? 3.1 is also pretty old. If you can upgrade, I'd recommend coming up to qt 3.3.3 or 3.3.4.

I don't see a mention of distro, but QT 3.1 is the minimum you need to get SEQ 5.x running. As long as you are running a relatively recent distro, you shouldn't need to build QT from source.

I fixed this problem for a long time by editing the config/make files and changing all references to "qt-mt" to just "qt". My standard QT installation is compiled multithreaded.

[dmkelly]

Thanks for the info guys, going to keep banging away at it. I compiled qt3.3.4 just to get current but ran into the same problem in that configue keeps pointing to the wrong library. Will start diging into the configure file and try to figure out why

[purple]

Maybe try running ldconfig and make sure QTDIR is set correctly pointing to your new version.

config.log pretty much says what it is doing:
configure:24132: g++ -o conftest -g -O2 -I/root/qt-3.1.2/include -Ino -L/usr/lib/qt-3.1/lib -Lno conftest.cc -lqt-mt -lXext -lX11 >&5

If libqt-mt.so isn't in any of the default library paths (set in /etc/ld.so.conf) and isn't in /usr/lib/qt-3.1/lib (taken from the commandline -L that config.log shows. The configure script probably gets that from QTDIR, or --with-qt-dir= or --with-qt-lib= params when you run ./configure), then the linker isn't gonna find it.

[dmkelly]

Thanks again guys, especially Purple. Got it to compile and am good to go. :)
