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 1.9 2007/10/14 20:26:47 apb Exp $
|
|
#
|
|
# Autoconf definition file for make.
|
|
#
|
|
# When you edit configure.ac:
|
|
# 0. Create the tools version of autoconf:
|
|
# 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" from "configure.ac":
|
|
# cd ${SRCDIR}/tools/make && \
|
|
# ${TOOLDIR}/bin/nbmake-${MACHINE} -f Makefile.regen
|
|
# (Please don't use a non-tools version of autoconf).
|
|
# 3. Test that nbmake still builds
|
|
# mv ${TOOLDIR}/nbmake ${TOOLDIR}/bin/nbmake.bak
|
|
# cd ${SRCDIR} && build.sh makewrapper
|
|
# 4. cvs commit files that you edited.
|
|
# 5. Regen again, to pick up changed RCS IDs from the above commit:
|
|
# cd ${SRCDIR}/tools/make && \
|
|
# ${TOOLDIR}/bin/nbmake-${MACHINE} -f Makefile.regen
|
|
# 6. cvs commit files that were generated.
