Split the process to fetch GNU tools (until now embedded within tools/Makefile.gnuhost) into a new Makefile.fetchgnu, MINIX-specific hence relocated, which is to be also used to fetch sources even when not building the tools. Use it for binutils too. Improve documentation. Also do not run configure on each run when MKUPDATE=yes The .WAIT serialization instruction between fetching and other configure sources was raising a new run of configure at each compilation. Avoid it by using two rules. Change-Id: Ie24950ccbb5c5067f3c1ea57b7bd8294e4c9445e

# Rules used to fetch a GNU package. Expects GNUHOSTDIST to be set
|
|
# and <bsd.own.mk> to be previously .include'd.
|
|
#
|
|
# New interface:
|
|
#
|
|
# * When using the `cleandir' target, defining CLEANFETCHED=yes will
|
|
# additionally remove all the fetched files.
|
|
# This is particularly useful when a GNU package is updated.
|
|
#
|
|
# The rest should be operations hidden to the normal programmers.
|
|
#
|
|
# How to use: (maintainers manual)
|
|
#
|
|
# * put a fetch.sh script one directory below the GNUHOSTDIST;
|
|
#
|
|
# * .include "path/to/minix/Makefile.fetchgnu", after having
|
|
# defined GNUHOSTDIST and before any use of the variable below;
|
|
#
|
|
# * insert ${fetch_done} as source before performing any operation
|
|
# on the files under GPL license which are usually found
|
|
# within NetBSD src/ tree;
|
|
#
|
|
# * rinse and repeat for every target which assumes the presence of
|
|
# these files, and for every Makefile operating upon them.

# TODO: does not handle correctly the cases where there are more than
|
|
# one package downloaded by fetch.sh (e.g.gnu/dist with texinfo+gmake):
|
|
# .gitignore only "protects" the first package which triggers.
