qt3

samon · 04-23-2002, 06:46 PM

I cann't compile any program that needs qt3, I have mandrake 8.2 and upgraded to KDE3 with qt3 and qt3-dev (contained in KDE) all programs give me the same error: (library qt-mt not found). I tried to configure with the option --with-qt-libraries=/usr/lib/qt3/lib and so on but nothing.
I tried export QTDIR=/usr/lib/qt3 and this did'nt help too
so what I'm doing wrong? thanx in advance

Did you check the /usr/lib/qt3/lib directory for libqt-mt? If it is there then you need to either add -L/usr/lib/qt3/lib when you compile it or add /usr/lib/qt3/lib to ld.so.conf.

I have KDE3 and Qt3 on Mandrake 8.2. Mine can find libqt-mt but it gives a bunch of undefined resources errors anyways.... I must be including either the wrong library or missing a library. I'm stumped.

I have run into what appear to be a couple bugs. This is from the Quick Start section of the Help files. Metric Conversion app.
1- Select clearPushButton for the Sender, clicked() for the Signal, numberLineEdit for the Receiver, and setfocus() for the Slot.
I have attempted to complete this step but there is no setfocus() option in the drop down menu for this (view and edit connections)

2- When I click Sender the drop down list textlabel1 is on the list and I dont think it should be and the toCombo box is not. I admit that I am new to Qt3 and c++ programming but I have attempted this same program 4 times and the same thing happens.

If you can in any way help I would appriciate it greatly.

I've read the following on the independent QT tutorial page...

Quote:

Some Linux distributions only include the multi-threaded version of Qt, called libqt-mt.so and not libqt.so. This means that ld will complain (when running gcc, g++ and other tools invoking ld, or running ld directly) that it cannot find -lqt. There are three ways to solve this listed below. I recommend the first solution.

* Change the qmake.conf file pointed at by QMAKESPEC by adding the word thread in the CONFIG += ... line.
* Change the .pro file for the project to be built by adding the word thread in the CONFIG += ... line.
* Compile Qt without multi-threading support to generate libqt.so.
* Put a link namned libqt.so pointing at libqt-mt.so in the lib directory.
