# $NetBSD: configure.ac,v 1.97 2019/06/22 13:42:53 hannken 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.
