I would like to install and use g++ 4-8 compiler. It supports various C++11 features, and I am willing to look into them and use them. Also, as I came here from Windows, my previous files also used C++11.

I looked for a moment and found this site. It contains .deb package with 4-8 gcc base. I downloaded it and installed, but synaptic shows that it isn't supported. Is there a way I can use it?

Also, please note that I am new to Linux - I migrated here literally few days ago and want to set things up. Therefore, I may not understand some fancy words or scripts.

Could you explain what you mean by synaptic shows that it isn't supported? What error message do you get? How did you try and install the package? –  terdon Oct 21 '13 at 18:43
    
Of course. I installed it using synaptic manager(I suppose; r-clicked on .deb file). It installed just fine, but gcc-base 4.7 still sits in my packages(synaptic shows it's installed). There are some icons in GUI, and the one that base 4.8 lacks is "package is supported"(although I have other packages without support and running). However, if I try to compile, it doesn't work. Should I also install new g++ from some other source, or? Because with gcc 4-.7 base I have gcc 4-7. I don't have any gcc 4-8. Just base. –  Matthew Oct 21 '13 at 19:31

Please edit your question to add new info rather than placing it in the comments, it is hard to read and easy to miss. A screenshot might be helpful as well. Anyway, you should also install gcc-4.8 which you will find on the debian packages page you linked to. –  terdon Oct 21 '13 at 19:35
    
Thank you. There are a lot of dependencies, and my distro is based on Debian Wheezy(stable), yet these are from sid. Is there easier way to download these(with apt-get?), or do I have to download them one by one? I also hope that this won't destroy anything in my system... –  Matthew Oct 21 '13 at 19:45
    
This is risky. It probably will be fine but you could run into problems and enter dependency hell. Since you only just moved to Linux, I would recommend simply using a newer distro, Debian testing for example. If that is not an option, you can always try and install the newer gcc, updating whatever it tells you to update. –  terdon Oct 21 '13 at 21:49
