I've been trying to get qt3 to work with Kdevelop in Kubuntu. I've downloaded and installed the qt-x11-free-3.3.5.tar.gz file from the trolltech site but Kdevelop still doesn't find the headers qapplication.h and qlabel.h. Anyone know how to get it running.

Try using Adept to download the matching kubuntu Qt & kdevelop packages.

Installing from a Qt tar.gz will put the header files & libraries in odd places and will require an enormous amount of faffing about symlinking everything here & there. I tried to do this myself (once).

I've also got something that may be similar to your issue

I'm coming from bloodshed's dev c++ and a bit confused here, when trying to run a hello world, I'm getting a message that there is no makefile and configure script - what is this?

and then after running ./configure I have this error message
checking for Qt... configure: error: Qt (>= Qt 3.2) (library qt-mt) not found. Please check your installation!

are these hand in hand?

let me make sense of that,

I WAS on bloodshed and now I'm trying to work in kdevelop Wink

I've solved it now. You have to use the QMake command rather than standard c++ methods. When you create a KDevelop project select a QMake 'hello world' rather than a standard one. The will run the QMake command for you. The other posibility is to create a folder (say hello with main file hello.cpp) then cd to that

folder and run qmake -project
then qmake hello.pro
finally make.

Obviously this is dependant on the correct tools being installed.

My problem was I just assumed that Qt uses standard C++ headers and could compile directly on a normal compiler. You have to run QMake first.

How you get it working in Dev-CPP I don't know.

I'm still wrestling with my above problem, and when I run, I get a message that there is no makefile, but I've quadruple checked, there's 3 makefiles upon opening the directory.

Confused

Three makefiles Confused

there should only be one at most. What happens when you try to run qmake -project. Remember that the folder the source is in should have the same name as the main source file. If you wrote the code using KDevelop there should be a src directory within the project folder. The source files would be in there. Copy them into a directory with the same name as the main source file then run qmake as I described above.

Make sure you run the qmake -main.pro step where main is the name of the folder the source is in. This will develop a Makefile you can then compile with make.

I'll give it a go. Thanks
