# $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.
|
