Which Version To Use?, Porting a Z appl to Windows/Linux Options

[Frederic Bergero...]

Hi,

I have developed a small application for my Zaurus. I would like to port it to Windows and Linux. The application uses Qt 2.3.2 and Qtopia 1.5.4.

On TrollTech's ftp site, I see this :

- QtWin230-NonCommercial.exe (for Windows)
- qt-x11-2.3.2.tar.gz (for Linux)

and :

- qt-x11-opensource-src-4.3.1.tar
- qt-win-opensource-src-4.3.1.zip

I'm wondering... Should I keep using Qt 2.3.x? or use Qt 4.3.1 for the desktop version of my application?

If I keep Qt 2.3.x, should I be worried by the difference between the version numbers : 2.3.2 vs 2.3.0? Is it a big deal? Anyone has experience with these versions? Also, it's mentioned in the README file of QtWin230, that I need Visual Studio but they don't say which version, neither if it's free or not? Anyone knows this information? Do I need a specific version or the latest one is ok. According to Microsoft's website, Visual Studio Express seems free (as in free beer) but I cannot find older versions.

Finally, do you think it would be too much hassle to migrate from Qt 2.3.2 to Qt 4.3.1? I don't think so but I would be curious if anyone has experience and/or comments on that. Do you think that would be possible to keep just one source tree using a lot of #ifdef or should I separate the code in two branches : zaurus and desktop (and the latter with #ifdef for Linux/Windows specific code)? What do you think?

Summer gets pretty slow here. You might also poke around the archives of the qt-embedded mailing list, and possibly join it to ask your questions. Don't have the mailing list url handy, but searches at google or http://trolltech.com should get you to the archive.

I read the list, but know nothing about answers to your questions.
