Qt5 QWidget project dependencies? OpenGL? Direct3D? WTH?
-
I just don't see the problem, but feel free to file a "bug report":https://bugreports.qt-project.org/. "Patches":https://codereview.qt-project.org/ are welcome as well.

You want something changed in Qt. There are two ways to achieve this, regardless whether it is a bug, a feature request or a change request: you either file a bug report so the QtProject might do the work for you or you do the changes on your own and submit them.
Moaning here at the forums does not change anything.

Nope, there are no ways to achieve this, one too many times have the requests of the community been arrogantly disregarded as groundless moaning of clueless idiots while the stupid decision behind Qt are being justified with every possible means.
How stupid is it to have a dependency on OpenGL and Direct3D in an application that doesn't use either??? Oh no, it is not stupid, it is just yet another of the brilliant decisions pushing Qt forward into a better and brighter future.
There are many decent people that have been quick to help me out when I needed help. And then there is you, with a "helping to preaching" ratio so low I'd appreciate it if from now on you refrain from following my every post with your dedicated pimping of an illusion of greatness and concern with the developer base. So I would really appreciate it if you cut the "political agenda" BS - if you are capable of such a feat, something that sadly cannot be said for most of fanboys out there.

I didn't mean to infantilize you.
I just don't see the relevance of your request in practice. This does neither mean that your requests are "...groundless..." that make you an "...clueless idiot..." and me the incarnation of ..."greatness and concern...", nor that I'm right and you are wrong - it just means that I have a different opinion on the question you've asked and the points you've raised, and that I do not find your arguments suitable enough to convince me of the contrary. That's the nature of discussions, and no reason to get into a huff.
Granted, the granularity of modularization can be argued over, most probably for all eternity. But I don't see the current one beeing disputable relating to dependencies, because there is still the option to not depend on stuff I do not want or need to, for example OpenGL or DirectX. Officially released shared libraries will always compel you to distribute stuff your application does not depend on, be it other shared libraries or data and code in existing libraries you do not use, because they are made to support any application, not a specific one.
It is indeed your right to think that I'm wrong and to demand changes if you think that a wrong decision has been made, by either filing a bug report or participating in development - of course at the risk that others don't find your arguments suitable enough as well. Not every decision you find "...stupid..." has to be actually stupid.
And I again invite you to join the Qt Development Mailing List and the Qt Open Governance Code Review to find out how and why decisions are made in the Qt Project.

I still cannot get the Qt5 executable to run on another system... Dependency walker wasn't much help - I get no errors, no notifications, no nothing, the exe just doesn't start. I managed to make it run on the development machine outside of Creator, but that's about it...
Those are the DLLs I added:
D3DCompiler_46.dll
libEGL.dll
libGLESv2.dll
msvcp110.dll
msvcr110.dll
Qt5Core.dll
Qt5Gui.dll
Qt5Widgets.dll
qwindows.dllHaven't added icu since I built Qt5 without the webkit...

In addition, deployment is a Windows issue only, a platform where Qt is usually deployed with the application anyways.

Entering a configure options list like the one below:
configure -developer-build -opensource -nomake examples -no-opengl -no-icu
Fails miserably

41 linker errors beginning with failing to build Qt5PrintSupport.dll.
That's miserable!

[quote author="Lukas Geyer" date="1359061129"]You may provide any other information than 'miserable' if you are out for decent help, like the Qt version you are trying to build, the compiler and the configuration and the actual linker errors.[/quote]
I'll try. As I said 41 linker errors are a lot to display. What would be the best way to illustrate them?
I downloaded version 5.0 for Windows 32-bit VS2010 to a Win 7 x86 machine with Active Perl, Python, Win SDK 7.1.
Ran configure without opengl , icu.
Ran nmake.
As nmake attempted to link Qt5PrintSupport.dll, Link errors. -

I think a "paste":http://pastebin.com/ of the failed compilation step including the linker errors should be sufficient.
In addition, I do recommend to use the "source package":http://releases.qt-project.org/qt5/5.0.0/single/qt-everywhere-opensource-src-5.0.0.zip found on the Downloads page instead of the 'Source' options of the SDK (they were different at least for Qt4, don't ask me why and if this has changed for Qt5).

As per your suggestions, I did the following:
I have been using the "source package" since the start of this issue. I copied the contents to: C:\Qt\5.0.0
I executed in the root folder: configure -opensource -nomake tests -no-opengl -no-icu
Output is posted "here":http://pastebin.com/Fcb2g4Tv

Hey Lukas, I posted my findings so as to obtain "decent help". Were you able to have a look?

[quote author="Lukas Geyer" date="1359571502"]Looks like you don't link against gdi32.lib for some reason. Do you build from a VisualStudio command line?[/quote]
I use the Windows SDK command line. I didn't notice any link errors relating to that lib.
