What do I need to install qt development libraries, so that I can then compile smplayer?

I can reasonably handle the C/C++ side of things, but I somehow always get lost whenever I try to set up a compiler/libraries, etc...

These instructions are from SMPlayer's Install.txt

       Generic compilation
       ---------------------------
            You need at least Qt 4.3 to compile smplayer.
            It won't work with an older version.
            Be sure you have installed the Qt 4 development package.
            Its name maybe qt4-devel, libqt4-dev or similar.

Unfortunately, this doesn't say much to me for two reasons.

  1. I simply don't know what "similar" means (eg. how can different packages be "similar"?)
  2. libqt4-dev, as mentioned, is in the Lucid repository, but I got a slew of 17 "unresolved dependencies" messages when I marked libqt4-dev in Synaptic Package Manager.. (I thought the package manager automatically included any required dependencies) ... Here is one of the messages: Depends: libqt4-script (=4:4.6.2-0ubuntu5) but 4:4.6.2-0ubuntu5.2 is to be installed

I'm thinking to use codeblocks for the IDE (because I've used it in Windows ("from whence I came", and ain't going back! :) ... Aside from the issue of what to install, will I need to explicitly tell codeblocks about qt, or will it install to a known library path?

have you added a ppa with qt packages (kde repo etc) ? – Alaukik May 16 '11 at 7:08
Why do you want to compile it in the first place? You can install smplayer from the repos (sudo apt-get install smplayer). – htorque May 16 '11 at 7:09
@htorque: Why... because I want to make a minor mod to it, to suit a particular preference, which it doesn't offer... – Peter.O May 16 '11 at 7:46
@Alaukik: No I haven't added a ppa for qt packages... If I do need this can you put "how" in an answer.. thanks. (but why would I need a ppa if it is in the repository..)... or do you mean I should not have added a ppa? – Peter.O May 16 '11 at 7:56
Please add the whole output of sudo apt-get build-dep smplayer to the question. – htorque May 16 '11 at 8:22

With help from both htorque's and Alaukik's comments, I stumbled upon the fact that my updates have been turned off (for 2-3 weeks), and it seems that qt simply needed the latest updates, which of course weren't there... I installed the latest updates and qt installed fine... Thanks htorque and Alauik.
