I am trying to install gcc4.9 and g++4.9 on my raspberry pi jessie.

I am following this tutorial, however when it comes to running:

sudo apt-get install gcc-4.9 g++4.9

I get:

Reading Package Lists..Done
Building dependency tree
Reading state information.. Done
E: Unable to locate package g++4.9
E: Couldn't find any package by regex 'g++4.9'

My sources.list is as follows:

deb http://mirrordirector.raspbian.org/raspbian jessie main contrib non-free
deb-src http://archive.raspbian.org/raspbian jessie main contrib non-free

I get the feeling I just need to another source in this list to be able to install it. But how can I find a source that hosts it, and is compatible with my Raspberry Pi Jessie?

You made a mistake in your command. It should be:

sudo apt-get install gcc-4.9 g++-4.9

  • Sorry, I made a mistake. I just typed it fast in here. That is the command I was running. – Chud37 May 19 '16 at 8:45
  • If you use Raspbian jessie you should have already installed gcc in version 4.9. To check this type: gcc -v – Huczu May 19 '16 at 8:49
  • Oh! If it's already installed how come it's not in the repo? – Chud37 May 19 '16 at 8:56
