make.conf used on rpi4 / Rock64 Pro (USER Necrose99) some bits swiped from Sabayon. for modularity.

  1. These settings were set by the catalyst build script that automatically
  2. built this stage.
  3. Please consult /usr/share/portage/config/make.conf.example for a more
  4. detailed example.
    1. https://github.com/necrose99/arm64-portage/blob/master/make.conf.production
  2. some of my greatest hits... granted i need to cleave much in this use flags repo.

  1. WARNING: Changing your CHOST is not something that should be done lightly.
  2. Please consult https://wiki.gentoo.org/wiki/Changing_the_CHOST_variable before changing.

  2. former PORTDIR="/usr/portage"

    1. QEMU ##

QEMU_USER_TARGETS="alpha arm aarch64 armeb cris i386 m68k microblaze mips mipsel ppc ppc64 ppc64abi32 sh4 sh4eb sparc sparc32plus sparc64 x86_64" QEMU_SOFTMMU_TARGETS="x86_64 arm aarch64 cris i386 m68k microblaze mips mips64 mips64el mipsel ppc ppc64 ppcemb sh4 sh4eb sparc sparc64"

USE_PYTHON="3.6"

PYTHON_TARGETS="python2_7 python3_6 python3_7 python3_8 python3_9"

  1. mgorny python hack tip. can force for newer 36 py.. etc.. if i get wind of coming py34 deprication
    1. python-3.5 tending to fuck with crap on rpi3-64 , server not so bad since newer ver.
    2. PYTHON_COMPAT_OVERRIDE='pypy3'
  2. pypy pypy3 wont build on 2 gigs+++ =< RPI3 has a gig.
  1. Some more forced targets
  2. update me .. PHP_TARGETS="php5-6"

RUBY_TARGETS="ruby25 ruby26 ruby27"

  1. ruby24 fails to comiple on rpi3 perhaps on Bannanpi64 or with more RAM, it will sit on R-PI3 for dayz....
  1. https://github.com/gentoo/dotnet layman -a dotnet

DOTNET_TARGETS="net45 net40 net50 net60"

  1. Setup GRUB platforms

GRUB_PLATFORMS="arm arm64"

  1. Support both 64bit and 32bit

ABI_arm64="arm64 arm32 lp64 lp32" ## would be a plus.

    1. PORTAGE CONFIG ##
    2. PORTDIR_OVERLAY="/usr/local/portage"

PORTDIR_OVERLAY="/var/lib/layman/"

  1. source /var/lib/layman/make.conf

CONFIG_PROTECT="/usr/share/config/kdm /etc /etc/conf.d /etc/init.d"

  1. /lib/modules mask is useful for our internal tinderbox

CONFIG_PROTECT_MASK="/etc/skel /lib/modules"

  1. Set PORTDIR for backward compatibility with various tools:
  2. gentoo-bashcomp - bug #478444
  3. euse - bug #474574
  4. euses and ufed - bug #478318
    1. xpak sometimes are usable othertimes metadata, dont sftp cleanly...
