Building Android 11 for VIM4 - which gcc version?

Hi Guys,
I’m trying to build the android source - something I haven’t tried before. I’m using Ubuntu 18.04 which I’ve seen in posts is compatible, but I can’t install the required version of gcc.

sudo apt-get install gcc-4.8-aarch64-linux-gnu

E: Unable to locate package gcc-4.8-aarch64-linux-gnu
E: Couldn't find any package by glob 'gcc-4.8-aarch64-linux-gnu'
E: Couldn't find any package by regex 'gcc-4.8-aarch64-linux-gnu'

I’m sure this is a noob problem - please can you advise? Thanks

@mph070770 It may not be necessary to install this tool. Can you try compiling the kernel first to see if there are any errors?

Thanks @goenjoy . I did get an error building u-boot and it looked like it was a gcc version issue. I’ll double check later and report the error.
