trouble with QT

Hi

I have problems with qt.
If I compile "scriptus" I get this message:

checking for Qt... configure: error: Qt (>= Qt 3.0.2) (library qt-mt) not found. Please check your installation!
For more details about this problem, look at the end of config.log.
Make sure that you have compiled Qt with thread support!

I have compiled qt with the -treads option and I habe qt newer than 3.0.2. I have qt 3.3.1

I found something in google that it could  have to do with gcc3 but i didn't understand that. Something with dll support...

Any Ideas?

Re: trouble with QT

Whatever shell you're building scriptus in probably hasn't sourced the qt login scripts.

Make sure you're using a login shell.

If you're building from an Xterm, add this line to your .Xdefaults

XTerm*loginShell: True

If you're building from an 'su' shell, make sure to type 'su -' so it actually logs in as root.  Otherwise it will not carry over several important environment variables.

Re: trouble with QT

I compile normaly in a nomal console login without any X.
Something is wrong with my qt or with QT at all.

If I try to compile gaiw I get following message:

g++ -c -pipe -Wall -W -g -D_REENTRANT  -DQT_THREAD_SUPPORT -I/usr/local/qt/mkspecs/default -I. -I/usr/local/qt/include -I.ui/ -I.moc/ -o .obj/moc_plotloaddialog.o .moc/moc_plotloaddialog.cpp
g++  -o gaiw .obj/main.o .obj/columnbreak.o .obj/MainDialog.o .obj/plotloaddialog.o .obj/qmake_image_collection.o .obj/moc_MainDialog.o .obj/moc_plotloaddialog.o  -L/usr/local/qt/lib -L/usr/X11R6/lib -lqt-mt -lXext -lX11 -lm -lpthread
/usr/bin/ld: cannot find -lqt-mt
collect2: ld gab 1 als Ende-Status zurück
make: *** [gaiw] Fehler 1

this is the same error. lib qt-mtis not there, why?
I build qt from ABS so I should have all the headers.

Is there anybody who solved this problem?

Re: trouble with QT

What is your output from the following three commands?

# ldconfig -p | grep libqt
# echo $QTDIR
# echo $PATH

Re: trouble with QT

Okay, ld is being stupid and can't find the library, even though it's in your ld.so.cache (this happens for me too).

Try adding the qt library dir to LDFLAGS yourself, during the make stage:

# make LDFLAGS+="-L/opt/qt/lib"

Re: trouble with QT

Hi

there is a new error

$ make LDFLAGS+="-L/opt/qt/lib"
/home/chris/bin/uic -L /home/chris/plugins MainDialog.ui -o .ui/MainDialog.h
make: /home/chris/bin/uic: Kommando nicht gefunden
make: *** [.ui/MainDialog.h] Fehler 127

The 3rd row means in english : Command not found
4th row: Error 127

Thank you for helping me

Re: trouble with QT

if .configure failes, how do you guys have a Makefile to run the make command?

Re: trouble with QT

i have the same problem, and yesterday with a friend we make some reverse.

./configure fail because during the various check and tests, first of look for qt libraries, the linker (ld) go into segfault. The script ./configure do not understand this and think the qt library is not on our system.

Looking arround the net, we found a ld bug that looks like this. This verify only on some amd systems. This explain why it segfault on my computer and not on my friend's pentium.

some discussion about:
http://lists.gnu.org/archive/html/bug-b … 00018.html
http://sourceware.org/ml/binutils/2005-07/msg00130.html

We have to wait a new binutils release..
