Installing Qwt 5.2.2 on Red Hat 9 + Qt 3.1

[amitahire]

Hello,

I am trying to install QWT 5.2.2 on Qt 3 but I get the following error. Can anyone help me? I already have Qwt 0.4.1(4.1) installed , was trying to install this over it.

This is what I get.

Qt 5.2.x needs Qt 3.3.x.

So which version is the latest which will work properly on Qt 3 ( or Qt 3.1)?

I am trying to find about the differnt version supporting compatibility but its little hard to search about the previous versions of Qwt.

Ok I had to look into documentation of all the version and I have found this :

Till Qwt 5.0.1 -> Qt 3.x and Qt 4.x+ is supportted
Qwt 5.0.2 - Qwt 5.2.2 > Qt 3.3.x and later.
And finally
Qwt 6 -> Only Qt 4.4 + ( Qt 3 support fully dropped.)

This is as far as I remember after going through all the documentations. Uwe or anyone, please add to it if anything is incorrect or incomplete about it. So that its help to other people. Thanks.

You know what? I get the same error with Qwt 5.0.0

Why isn't the QPaintBuffer class compling? Anyway help me with it. I am using Qwt 0.4.1 now, I thought maybe I will upgrade the thinga I can. (Using Qt 3-1 and Red Hat 9 - Cant change)

Ok finally managed to compile qwt 5.0.1 (have to test) but tell me one thing, its not possible to compile plugin in Qt 3.1?

Where are these header files???

#include <QtPlugin>
#include <QDesignerFormEditorInterface>
#include <QDesignerFormWindowInterface>
#include <QDesignerFormWindowCursorInterface>
#include <QExtensionManager>
#include <QErrorMessage>

#include <QtPlugin>
#include <QDesignerFormEditorInterface>
#include <QDesignerFormWindowInterface>
#include <QDesignerFormWindowCursorInterface>
#include <QExtensionManager>
#include <QErrorMessage>

So I am guessing that Qwt plugin for Qt 3.1 is not available??
