qt - what is arm-linux-gcc and how to install this in ubuntu

Question

In compiling qt I found that there is a qws target called arm-linux-gcc. I looked around a bit but unable to figure out how and where to find this. I tried installing and apt-cache gave me following output.

I think this has my system's arm compilers. Could some one assists to figure out to install "arm-linux-gcc"

Answer 1

You are missing the gcc compiler with arm target set. This has been prepackaged in the ubuntu archive for quite a while, so you shouldn't need to build this from source.

sudo apt-get install gcc-arm-linux-gnueabi to install
