For my current project we are having an issue which we can solve if we are able to recompile the arm toolchain (gcc, c++stdlib, nanolibc, etc) from source.
From the arm website I can download a snapshot of the source. I found a blog but it's outdated. The pdf he refers to no longer exists in this snapshot anyway.
Browsing through the extracted archive I can't seem to find any instructions how to compile.
Where can I find documentation how to compile arm-none-eabi from source?
