After all that [UPDATE]

After all that effort I uninstalled Qt5 lol. It’s good but I didn’t like it and here’s why (in order of most hated to least hated):

1) It doesn’t show you which files have changed since the last commit. In Eclipse it shows a right triangle on all the files that have changed.
2) The diff is crap! It doesn’t show it as a left and right file with differences highlighted. It’s just the diff output.

I might just go back to Eclipse…or Netbeans…

I’m going to give QtCreator another chance. I felt I wasting time looking for other IDEs and features rather than focusing on my project.

Programming, Ubuntu

Qt 5.1.0 on Ubuntu 12.04 LTS

Here are instructions to running Qt 5.1.0 on Ubuntu 12.04 LTS. Please note that I got it working on a virtual machine, here are the details:

  • VMware Player 5.0.2 build-1031769
  • New install of Ubuntu using image “ubuntu-12.04.2-desktop-amd64.iso”

Step 1
Get Ubuntu running on the VM, I’m not going go through all that. Once Ubuntu is ready, install the OpenGL development libraries:

sudo apt-get install libgl1-mesa-swx11-dev (see update below)
sudo apt-get install libgl1-mesa-dev

NOTE: I used the mesa libraries because I didn’t have the drivers for my graphics card.

Step 2
Download Qt from their website. I used this “”.

Step 3
Install Qt:

chmod a+x
sudo ./

NOTE: I installed using sudo so that I can install to /opt/ so that everyone has access. For some reason when I installed it to /opt/, the examples directory has no permissions at all. I don’t know why it does that but here’s how you fix it:

sudo chmod -R a+rwx /opt/Qt5.1.0/5.1.0/gcc_64/examples

Step 4
Now you can run the examples. Run the examples from their original directory (in my case it is /opt/Qt5.1.0/5.1.0/gcc_64/examples) because some of the examples have code in folders outside their source folder.

I have tried the following examples and they work:

  1. Analog Clock
  2. Application
  3. Calqlatr*
  4. OpenGL Window*
  5. Same Game*

* Hang on, hang on! I’ll explain in the next section 🙂 See update below.

Yay! I finally got the OpenGL applications working (I’ve struggling for a day to get it working, it turned out i was using the wrong OpenGL mesa libraries). However, it appears that the color black is displayed transparently. WTF you ask?? Don’t look at me 😛

Does anyone know WTF is going here??

Problem fixed!! Yay!!

Use the “libgl1-mesa-dev” package and all is ok. This is because Ubuntu by default installed “libgl1-mesa-dri-lts-quantal” and the matching dev package is “libgl1-mesa-dev” (see
