Tutorial 7 and Dev-C++

[swarm32]

Setup: Dev-C++ 4.9.9.2 & Qt 4.3.2 on Windows 2000 SP4
Used these sites to help me set up QT & Dev: http://darkhack.googlepages.com/qttutorial ; http://www2.norwich.edu/mfenner/SE/f...-qt-notes.html

Exact tutorial version: http://doc.trolltech.com/4.3/tutorial-t7.html

When I go to compile I get this lovely message:

[Linker error] undefined reference to `vtable for LCDRange'
[Linker error] undefined reference to `vtable for LCDRange'
[Linker error] undefined reference to `vtable for LCDRange'
[Linker error] undefined reference to `vtable for LCDRange'
ld returned 1 exit status
C:\is301\qt\ch7\Makefile.win [Build Error] [tutch7.exe] Error 1

My Compiler output looks like this:

If I try to manually compile I run into a different problem:

Tried to do what was suggested here (http://www.qtcentre.org/forum/archiv...php/t-567.html) but the errors just got uglier.

Any ideas?

What happens when you run "make clean" and then "make" from the console?

For S&G after looking at the output I did this:

C:\is301\qt\ch7>cd release

C:\is301\qt\ch7\release>dir /w
Volume in drive C has no label.
Volume Serial Number is 0884-CE14

It appears that the manual method does create a valid example. Any idea how to get Dev-C++ to behave? Or should I go back to using Crimson Editor and batch files?

Thanks in advance.

I don't use it, but you should be able to force it to run makefiles generated by qmake. Of course this means that you will have to edit the .pro file by hand and run qmake from time to time, but maybe there is some kind of plugin that does this.
