[alpine-devel] Re: Cross-compilers [was: Re: [alpine-aports] [PATCH 2/3] testing/gcc-arm-none-eabi: New aport]

Hi,

how about providing a single APKBUILD for all cross-compilers targeting
embedded bare-metal platforms and using subpackages to create the actual cross
compilers?

The attached APKBUILD implements this for gcc. The same should approach could
be applied to binutils, newlib (in case of non-AVR devices) and gdb (in case of
non-AVR devices). Also C++ support should be provided (at least for AVR
devices) to enable users to use Arduino. (Right now I disabled it for faster
packaging time.)

Btw: Is there a way to not create the base package?

Kind regards,
Marian
