# SliTaz package receipt.

PACKAGE="slitaz-toolchain"
VERSION="6.0"
CATEGORY="meta"
SHORT_DESC="SliTaz meta package to rebuild or install current toolchain."

DEPENDS="binutils linux-api-headers glibc-dev gcc make elfkickers"

# The goal here is to build and install SliTaz toolchain. We build the toolchain
# from SliTaz packages, on SliTaz and for SliTaz so in case of new and important
# toolchain upgrade we must build Binutils a first time, then GCC so it use the
# new Binutils. After we cook Glibc and then rebuild Binutils + GCC a second
# time so they are linked with the new main GNU libc. We usually also due a
# bootstrap by recooking slitaz-toolchain a second time so we are sure it can
# rebuild itself.
#
# SliTaz does one big toolchain by year just after the stable release, any change
# here or in the toolchain packages version must be discuss on the mailing list.
