# Amiga C toolchain: Bebbo's m68k-amigaos-gcc 6.5 (AmigaPorts), with
|
|
# binutils, libnix, clib2, the NDK 3.2 headers and vasm. Built from source
|
|
# (~15-40 minutes).
|
|
#
|
|
# The build clones its sub-projects by BRANCH name, which would make the
|
|
# result drift; every sub-project is pre-cloned here at a pinned commit so
|
|
# the Makefile finds it in place and skips its own clone. It also wget's
|
|
# the NDK and ixemul SDK on every build; those are checked afterward.
