Compiling error with wwWidtes.qt 4.6.2

[Andrewshkovskii]

Hello all!
i build wwwidgets like this :
qmake -spec win32-g++ -r CONFIG+=release,
Mingw32-make-install.
and now i got a problem with compiling simple project with wwWidgets :
.pro

TEMPLATE = app
SOURCES += main.cpp
CONFIG += wwwidgets

#include <QtGui/QApplication>
#include <QwwTwoColorIndicator>
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QwwTwoColorIndicator id;
    id.show();
    return a.exec();
}

#include <QtGui/QApplication>
#include <QwwTwoColorIndicator>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QwwTwoColorIndicator id;
    id.show();
    return a.exec();
}

To copy to clipboard, switch view to plain text mode 

buildind in release. So, i got error message :

testWWW/../../Qt/include/wwWidgets/qwwtwocolorindicator.h:21: undefined reference to `QwwPrivatable::~QwwPrivatable()'

But QwwPrivatable is defined in #include <wwglobal.h> witch is including in all qww classes.
Why is happening and what i'am doing wrong?
Because every example coming with wwWidgets is compiling, cleaning and re-building and qmake'ing as well, as normal project.

Is this the only error you are getting?

[Andrewshkovskii]

Hello, Wysota
yes, it is only compilation i get, but i cant understand, why wwW examples are compiling, my projects - not?

[wysota]

I would guess you are not linking with the library but it's just a guess. Could you provide the whole compilation log for your project (please attach it as a file to your post)?

[Andrewshkovskii]

here it is!

[wysota]

Could you post the complete project here so that I can try to reproduce the problem myself? Either the log is mixed up or the project builds and then something fails but I need to see the actual code, maybe there is a bug in wwWidgets.

[Andrewshkovskii]

It's very simple code, with one your widget at all.. May be i build and install wwWidgets wrong or something?

[wysota]

It compiles without problems on my machine (after removing the incorrect include from main.cpp, of course). How exactly did you install wwWidgets? Do you have the latest version (0.9.6)?

[Andrewshkovskii]

#include "C:\storage\programming\wwWidgets\widgets\wwglobal _p.h"

this incorrect include? ok, i removed it, but nothing happened.
I removed widgets and re-install them now by :

C:\storage\programming\wwWidgets>qmake wwwidgets4.pro -spec win32-g++ -r CONFIG
+=release
Reading C:/storage/programming/wwWidgets/widgets/widgets.pro
Reading C:/storage/programming/wwWidgets/plugin/plugin.pro

C:\storage\programming\wwWidgets>mingw32-make

And now i get this make error

So, i copy wwwidgets4.dll, rename it to wwwidgets4d, and put it into

...\wwWidgets\widgets\debug and ..\wwWidgets\widgets\release

and run make again, after make finished, i installed wwwidgets (make-install) and it installed.
So, i think the compilation error was caused becouse of my actions with *.dll files.

[Andrewshkovskii]

I fixed this error with adding CONFIG-=debug to plugin.pro, and run mingw32-make , mingw32-make install again, so it compiled
But project compiling is failed again with message :

And designer say's that wwwidgetsplugin.dll could not be found/loaded, but wwwidgetsplugin.dll is in /Qt/plugins/designer/ directory.

[wysota]

Start from scratch, unpack the archive, cd into the "widgets" directory, run qmake, run make, run make install, cd ../plugin, run qmake, run make, run make install. Everything should be fine then - it's a foulproof method of installing this particular widget set - it should create a debug and release version of the widget set and release version of the designer plugin.
