I wonder if it's possible to use QT3 instead of QT4 on windows, because in the trolltech website [1] there are only the qt4 available for download.
I would like to test sw both under linux and windows.
Thanks
Stefano
[1] http://www.trolltech.com/developer/downloads/qt
you might look at http://sourceforge.net/projects/qtwin this is a port of qt3 to windows.

Thanks. :P
I am installing them now.
Stefano
I have finished the installation process, using the batch file "configure-mingw.bat", with success, but C::B won't compile the tutorial 1 of the qt.
I removed the qt4 installation and I modified the PATH because was "C:\QT\4.2.2" now is C:\INSTALLQT3.
PATH=.......;C:\MinGW\bin;c:\installqt3\bin;C:\installqt3\include
Just for info I am using the last nightly build, that with QT4 was building perfectly.
the error I got is :
Compiling: C:\installqt3\tutorial\t1\main.cpp

Find out why the two headers qapplication.h qpushbutton.h are not being included.
If you did not know QApplication and QPushButton are NOT declared. You need to find out if qtfree supports them and which header is needed. (qpushbutton.h for QPushButton)
It is helpful to turn on Compiler logging to Full command line.
"Settings" -> "Compiler and debugger" Tab "Other" Set "Compiler logging" to "Full command line"
Tim S
Thanks but I believe the problem it's in the environment variables but I don't understand where.
The qapplication and qpushbutton are in installqt3/include, and this directory is in the PATH as per my previous message.

The fact that it is in the PATH means nothing to the compiler. You have to explicitely add to the compiler search dirs.
Thanks a lot Mandrav.
So, if I have understood well, adding to the Global Compiler Variable :
Base : C:\installqt3
Include : C:\installqt3\include
lib : C:\installqt3\lib
and specifying in the compiler and debugger settings :
$(#qt)
$(#qt.include)
$(#qt.lib)
would be what you told me. Right?
It seems to look at this directories but don't seems to be enough.

Thanks in advance for any comments.

Your compiler search dirs are fine now. It compiles but it doesn't link. This means that you forgot to link to all needed libraries. I can't tell you which exactly are those because I don't use Qt...
Thanks. :(
I will try again to solve this problem and maybe at the end, if with success, I will post the solution to update the website of qtwin[1] : no C::B !!!!
Am I alone to use QT3 under windows?
Thanks
Stefano
[1] http://qtwin.sourceforge.net/qt3-win32/index.php
I use Qt3 with Visual Studio 6.
The line added to the dsp file (the project file of VS) to link the libs is (release and debug version):
[RELEASE VERSION]
# ADD LINK32 "qt-mt334.lib" "qtmain.lib" "kernel32.lib" "user32.lib" "gdi32.lib" "comdlg32.lib" "advapi32.lib" "shell32.lib" "ole32.lib" "oleaut32.lib" "uuid.lib" "imm32.lib" "winmm.lib" "wsock32.lib" "winspool.lib" "kernel32.lib" "user32.lib" "gdi32.lib" "comdlg32.lib" "advapi32.lib" "shell32.lib" "ole32.lib" "oleaut32.lib" "uuid.lib" "imm32.lib" "winmm.lib" "wsock32.lib" "winspool.lib" "opengl32.lib" "glu32.lib" "delayimp.lib" delayimp.lib /nologo /subsystem:windows /machine:IX86 /libpath:"$(QTDIR)\lib" /DELAYLOAD:comdlg32.dll /DELAYLOAD:oleaut32.dll /DELAYLOAD:winmm.dll /DELAYLOAD:wsock32.dll /DELAYLOAD:winspool.dll
[DEBUG VERSION]
# ADD LINK32 "qt-mt334.lib" "qtmain.lib" "kernel32.lib" "user32.lib" "gdi32.lib" "comdlg32.lib" "advapi32.lib" "shell32.lib" "ole32.lib" "oleaut32.lib" "uuid.lib" "imm32.lib" "winmm.lib" "wsock32.lib" "winspool.lib" "kernel32.lib" "user32.lib" "gdi32.lib" "comdlg32.lib" "advapi32.lib" "shell32.lib" "ole32.lib" "oleaut32.lib" "uuid.lib" "imm32.lib" "winmm.lib" "wsock32.lib" "winspool.lib" "opengl32.lib" "glu32.lib" "delayimp.lib" /nologo /subsystem:windows /debug /machine:IX86 /pdbtype:sept /libpath:"$(QTDIR)\lib"
May be it is too long, but you can see that the Qt3 lib is "qt-mt334.lib". You should have a similar library that must be added to your project options. Note that "334" is the version (I use 3.3.4), that may change. Note also that "mt" means multi-threaded and also this depends on how you compiled your library (mt is the default mode).
I hope this helps!
Alessandro
Uhm... I believe this is the point.
I did again "compile-MinGW.bat" to see if it was lissed womething during the compilation process, and at the end I see :
"The Qt library is now built in ./lib"
"The Qt examples are built in the directories in ./examples"
"The Qt tutorials are built in the directories in ./tutorial"
ECHO disattivato.
"Enjoy! - the Trolltech team"
ECHO disattivato.

No .lib ! Searching for any .lib files I don't find something similar to yours libs.
What do you think about it?
Stefano
You are using GCC he was using MSVC.
The normal library naming is different.
GCC is in the form libxyz.a
MSVC is in the form xyz.lib
Where the library name is xyz
Tim S
Tim is right, try to use the file 'libqt-mt.a'.
