How To Install Qt 5.0.x in Linux Mint

sierdzio, I've updated your dependencies wiki with some novice friendly information. Someone before me seemed to have heavily removed a lot of the stuff you wrote. You might wanna have a look at that.

Yeah, that's done by Qt devs, because not all packages are required when using prebuilt Qt. Especially *xcb-dev stuff is not required.

Hi. It's been awhile since my post but with Mint 15 out I updated with Qt 5.0.2. What I realize was that libx11-xcb and libglu1-mesa was installed by default. Thing is, it doesn't suffice for Qt 5 applications to compile. They compiler complains some GL/ bla bla header cannot be found. So I updated here and the wiki:
@
sudo apt-get install build-essential
sudo apt-get install libx11-xcb-dev libglu1-mesa-dev libxrender-dev
@

I'm not quite sure whether libxrender-dev or libx11-xcb-dev is really needed cause I tried installing it first and it didn't work. Only after libglu1-mesa-dev is installed did Qt 5 start working properly. "^libxcb.*" is confirmed not required.

anyhow, updated the 1st post to match my findings

Hi bruceoutdoors and flocks,

I am new to Linux (few days) and I want install the JACK and ALSA plus the Qt. Because I need to do the music composing and production. I have search for so many hours/days and cannot find the way that is easy for the beginers. Thanks for bruceoutdoors has this guidence and I am able to install the QT.

However, ladies and gentlemen, anyone can help me/ tell me the clear instruction to downloan and install JACK and ALSA in Linux Mint 15. There are so many package in the website. I don't know which package that I really need. And please give me clear instruction to install, like bruckoutdoors did.

Much obliged.

Hello Joew.

I'm glad that to see my article has been of use to someone (:

However, I'm afraid the issue regarding ALSA and JACK is out of the context of this forum. Personally I don't use them though... everything audio related is handled by audacity, and I don't do any MIDI composing.

Thanks, this post post got me up and running on linux mint 15.
To me, this issue doesn't present as a missing dependency, but as a bug.

The application said it could not find gcc, which was already installed. Now I can see that it was actually looking for g++. Even now on the Options->Build Compiler tab, it says it found gcc, but if you look at the path, it found g++.

The questions is - what is the bug? Should it really use gcc rather than g++? Or are the screen labels and error messages wrong?

Thanks,
Bruce

uh... are you compiling stuffs in Qt now? Are you running Qt 5.1? I haven't really used Qt for time, so...

It uses g++ btw. I never once seen Qt Creator looking for gcc before...

Yep - I can build and run the examples using 5.1.1

It may just be my inexperience with gnu - In the past I used borland and ms compilers. But on the options->build->compiler tab, the screen specifies gcc, and yet the auto entry is for g++. In retrospect, it didn't cause the issue, but it did cause me some confusion - I take software tools very literally :)

The matter is rather simple: GCC nowadays stands for GNU Compiler Collection. In that it encompasses a C compiler (called gcc), a C++ compiler (called g++) and a few others (fortran, etc.).

Names change over time, but in general, if people say GCC but talk about C++, they mean g++ ;)

Thank you very VERY MUCH for your explanation. I spent 2 days to find whats wrong with my Linux (or Qt). I can't even count how many documents I found that just make thinks worse. Thank!!!
