PinePhone Cross Compiler Install

[dgdimick]

I'm trying to install a GCC cross compiler so I can write so really bad code for when my PhinePhone gets here; a 5th grader is probably a better coder then I am.

Anyway, I'm using these instructions, and it work just fine untill I try to install glibc

Code:

make -j4 csu/subdir_lib

returns this

Any ideas? Or am I just doing this wrong, like there's already as package to install?

I'm running on an old laptop that has Ubuntu installed.

I would expect ubuntu to have a packaged crossdevelopment toolchain available - there's gcc-aarch64-linux-gnu at least. It probably depends which distro you're targeting though - for example PostmarketOS has a script that builds its own crossdev environment.

Here's a couple of instruction/discussion pages on cross compilation for Gentoo, maybe you will find these useful or get some direction from reading these:
