Towards automake XI patch from Ralf Corsepius <corsepiu@…>:

This patch is the most scary of all proposals I've been mailing to you
this week until now.

It consists of 3 parts:

  1. a patch
  2. a perl script (acpolish)
  3. a shell script wrapper to invoke the perl-script.

The perl-script reads in each and modifies them
("polishes/beautifies" them :-).

These modifications are not easy to describe:

Basically, it hard-codes some automake Makefile-variables and rules into
RTEMS autoconf-Makefile.ins (Note: autoconf vs. automake!!) and converts
some settings/variables to configure scripts' requirements (Yes,

E.g. it adds the automake standard variables $top_builddir and $subdir,
adds dependency rules for automatic re-generation of Makefiles from, adds support variables for relative paths to multiple
configure scripts etc.

The patch is a one-line patch to enable the support of the new features
added by acpolish.

The shell script is a wrapper which pokes around inside of the source
tree for Makefile.ins and invokes acpolish on all autoconf-Makefile.ins.

acpolish is designed to be able to run several times on the same and may once become a more general tool to convert RTEMS to automake. Therefore, I'd like to keep it inside of source
tree. (e.g. as contrib/acpolish or c/update-tools/acpolish). However, it
doesn't make sense to export it outside of RTEMS.

To apply this:

cd <source-tree>
patch -p1 -E < <path-to-patch>/rtems-rc-19990318-1.diff
tar xzvf <path-to>/rtems-rc-polish.tar.gz

Note: The path contrib/acpolish is hard-coded into, if
you decide to put it in an alternative place, please modify to reflect this change.

cvs rm make/rtems.cfg (It isn't used anymore)
cvs add contrib
cvs add contrib/acpolish
cvs commit

I've tested this intensively, but naturally I can't exclude bugs.


PS.: Most probably, this is the last "Towards automake" patch. The next
one probably will be a real automake patch.
