This commit finalizes support for cross compilation. The tools directory are all links to the actual tools and are built on the host system to build Minix. build.sh is the work horse that takes care of all environment settings. It's slightly adjusted for Minix. The /usr/src/Makefile has additional targets needed for cross compilation.

# $NetBSD: configure.ac,v 1.74 2011/11/03 14:13:53 joerg Exp $
|
|
#
|
|
# Autoconf definition file for libnbcompat.
|
|
#
|
|
# When you edit configure.ac:
|
|
# 0. Create the tools versions of autoconf and autoheader:
|
|
# cd ${SRCDIR} && build.sh -V MKMAINTAINERTOOLS=yes tools
|
|
# (This might not work if you try it after editing configure.ac.)
|
|
# 1. edit configure.ac
|
|
# 2. Regenerate "configure" and "nbtool_config.h.in" from "configure.ac":
|
|
# cd ${SRCDIR}/tools/compat && ${TOOLDIR}/bin/nbmake-${MACHINE} regen
|
|
# (Please don't use a non-tools version of autoconf or autoheader.)
|
|
# 3. Test that the tools still build:
|
|
# mv ${TOOLDIR} ${TOOLDIR}.bak
|
|
# cd ${SRCDIR} && build.sh -V MKMAINTAINERTOOLS=yes tools
|
|
# 4. cvs commit files that you edited.
|
|
# 5. Regen again, to pick up changed RCS IDs from the above commit:
|
|
# cd ${SRCDIR}/tools/compat && ${TOOLDIR}/bin/nbmake-${MACHINE} regen
|
|
# 6. cvs commit files that were generated.
