Qt Becomes LGPL

Aequo writes "Qt, the highly polished, well documented, modern GUI toolkit owned by Nokia, will be available under the LGPL starting with version 4.5! It was previously only mainly available under the GPL and a commercial license. Selling licenses was an important part of Qt under Trolltech as it was the company's main source of income, but Trolltech is a fruit-fly compared to Nokia, who want to encourage and stimulate the use of Qt Everywhere [PDF]. This is fantastic news for all commercial developers looking to create cross-platform applications without the need to buy a $4950 multi-platform license per developer."

    Seriously though- Reasons to write applications for the gnome desktop environment are getting fewer every day. When QT4 became available under the GPL on all 4 major platforms- Windows/BSD/Linux/OSX the argument for GTK was weak. Now, I'd argue its virtually non-existent.

      When QT4 became available under the GPL on all 4 major platforms- Windows/BSD/Linux/OSX the argument for GTK was weak. Now, I'd argue its virtually non-existent.

      The argument was primarily a licensing one: LGPL versus GPL. Going for GTK+ because it was LGPL wasn't a weak argument.

      With both QT and GTK+ being LGPL, the argument will be about toolkit quality, third-party support and language experience (C++ versus C). This is a much more useful comparison, and as a developer well-versed in GTK+ I'm looking forward to using both.

      From QT4.5 onwards, the best tool for the job wins. Thanks Nokia!

      Firstly, without competition, things tend to languish.

      Competition is great, however GNU/Linux should not be competing against itself. There is too much fragmentation in Linux-land, 10 apps that all try to do the same thing, but each one does certain aspects better, yet none get it all right. Instead consolidate all that effort to 2 or 3 apps.

      Linux gets to compete against Windows and OS X. Are you old enough to remember the Unix-wars? All the big Unix versions were all doing things their own way whilw MS and Apple were working on more consistent offerings. We all know what happened to the major Unix players.

      Sadly, Linux desktop seems to be repeating the past. Constantly reinventing the wheel with tons of yet-another-app-X syndrome.

      I have been using Linux since early Red Hat days. Then I used Slack, built my own Linux based on LFS for about 2 years. Then on to Gentoo, then to Fedora then finally Ubuntu.

      Ubuntu made things a lot better IMO, however it still suffers with a felling of many apps tacked together instead of a more cohesive product. This was the main reason I switched to OS X 2 years ago and have been happy with that choice.

      I still find myself missing Linux and would love to see a more unified final product. I don't want to have to be bothered with looking for a Gnome/GTK+ based app for Ubuntu so it works/integrates best.

      There have been too many times I where I couldn't find a good Gnome/GTK+ based app but found it with a KDE based app. However, that one app pulls in a lot of KDE based bloat that I don't want/need. So I would try to switch to KDE from Gnome for a while, but found the same issue where I would have to pull in/use a Gnome/GTK+ based app.

      Lather, rinse, repeat.

    I love to see when a company understands that giving something away they will get ten times more in return. And nowadays that happens too rarely.

    For a while it seemed that Nokia is about to lose to its competitors, because of Symbian and bad software. This will totally remedy it. I've also heard from Nokia insiders that they're actively dumping everything related to Symbian. It won't take more than couple of years and all their phones use Qt.

    Seeing how well Apple has been selling iPhone applications, I can only imagine the potential Qt phones have in future. With Symbian that just wasn't possible, it was a total nightmare for the developers.

    Think about Xfree. it was basically a closed monopoly. Then X11 grabbed it and opened it up further. Has it improved things? Absolutely. Basically, we NEED competition. GNOME is good competition, vs. say MS's form of competition (involving lots of dirty tricks and legal maneuvers).

    I'm assuming we're talking about development for Linux, or cross platform here, since this is QT. Two questions:

    1) Why would you program in C# on Linux? Mono support is years behind the feature sets that MS is rolling out. There are a variety of languages/frameworks that are better supported than .NET.

    2) What's wrong with GUI programming in C++? QT tools seem pretty nice to me, and objects are much easier to work with than a mountain of procedural code. C++ should also be plenty efficient for application space.

    So, what advantages are there in using C/Gnome?

    Flat out wrong. The GPL restricts what you can do with other peoples code who have chosen to license it under the GPL. If you don't want those restrictions on your code then don't creative derivative works from GPL code.

  11. Re:Yeah but KDE doesn't work. by Enderandrew · · Score: 5, Insightful

    The Ubuntu devs screwed up their KDE 4 packages in a bad way. That isn't KDE's fault.

    Furthermore, KDE doesn't depend on video drivers. If the Ubuntu devs made a certain Nvidia driver a dependency, then they screwed up big time. KDE does not change your kernel or video driver in any way.

    I'm not calling you a liar or saying you didn't have problems. I'm sure your box got hosed somehow, but it is more likely the problem was with Ubuntu's packaging.

    It should also be noted that the QT 4/Nvidia problems have largely been remedies. Qt 4 used Xrender heavily, and Nvidia's driver had a piss-poor Xrender implementation. The forthcoming Qt 4.5 is supposed to move away from using Xrender all over the place, and the latest Nvidia driver has much better Xrender support to boot. openSUSE even provides a repo with weekly snapshots of the KDE 4.2 branch compiled against the weekly snapshots of Qt 4.5. In theory it is unstable, but I've had good luck with it so far.

    I know I'll get modded Troll for this, but I don't care. Ubuntu has got some serious problems, and is very overrated. openSUSE puts out quality KDE 3, KDE 4 and Gnome desktops. They support all 3 currently (though KDE 3 is being dropped in the future).

    Novell hires a large staff of developers that make quality packages, fix upstream bugs, backport features, etc. As much as I hated Novell for the MS deal, Novell is one of the best contributors to several upstream projects, and openSUSE is a fantastic distro.

    I can't recommend it enough.

    The definition of derivative work is the issue.

    I'd love to be able to utilize GPLed code, provide the code, credit the author(s), and create a work that utilized that functionality, intact, as an accoutrement to the rest of the application.

    Unfortunantly, a strict reading of the GPL leads me (and my companies OSS group) to believe that this would mean that my entire application is a derivative work that would fall under the GPL. I've gotten around this in the past by having the GPLed code in a plugin form that is dynamically specified and then dynamically loaded so that the application is significantly distanced from the GPLed code.

    Perhaps that's not how the GPL is intended to work, but there's enough leeway in interpreting it, that you have to be really careful.

    The problem is that you're criticizing the GPL for not living in your perfect dream world.
    I think the GPL is way better, because I know, that in reality, businesses tend to rip you off, fuck you in every hole, and leave you bleeding on the street, (metaphorically speaking) if they just can!
    It's the rule of profit maximization. The first rule of every business. And more often than not, it's unfortunately the only rule.

    And that's exactly why we need the GPL to enforce giving back something. Because in reality, businesses will not give back anything. Why would they? To lose money and then to lose against their competition who is winning because they are not giving anything back? Makes no sense.

    But why would you care about your reality, if you can perfectly continue to rant about your dream world not coming true, while ignoring it?
