From d8ff79366bb0f4646436e4c298e4f5505a51c007 Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Fri, 19 Mar 1999 22:27:02 +0000 Subject: Towards automake XI patch from Ralf Corsepius : 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 Makefile.in 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, plural). E.g. it adds the automake standard variables $top_builddir and $subdir, adds dependency rules for automatic re-generation of Makefiles from Makefile.in, 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 Makefile.in and may once become a more general tool to convert RTEMS Makefile.in 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 patch -p1 -E < /rtems-rc-19990318-1.diff tar xzvf /rtems-rc-polish.tar.gz ./rtems-polish.sh ./autogen Note: The path contrib/acpolish is hard-coded into rtems-polish.sh, if you decide to put it in an alternative place, please modify rtems-polish.sh to reflect this change. Later: 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. Ralf. PS.: Most probably, this is the last "Towards automake" patch. The next one probably will be a real automake patch. --- c/src/lib/libbsp/i386/pc386/tools/Makefile.in | 18 ++++++++++++------ 1 file changed, 12 insertions(+), 6 deletions(-) (limited to 'c/src/lib/libbsp/i386/pc386/tools/Makefile.in') diff --git a/c/src/lib/libbsp/i386/pc386/tools/Makefile.in b/c/src/lib/libbsp/i386/pc386/tools/Makefile.in index 14383ab284..e2883c9c2a 100644 --- a/c/src/lib/libbsp/i386/pc386/tools/Makefile.in +++ b/c/src/lib/libbsp/i386/pc386/tools/Makefile.in @@ -4,11 +4,17 @@ @SET_MAKE@ srcdir = @srcdir@ -VPATH = @srcdir@ -RTEMS_ROOT = @top_srcdir@ -PROJECT_ROOT = @PROJECT_ROOT@ +top_srcdir = @top_srcdir@ +top_builddir = ../../../../../../.. +subdir = c/src/lib/libbsp/i386/pc386/tools INSTALL = @INSTALL@ + +RTEMS_ROOT = $(top_srcdir)/@RTEMS_TOPdir@ +PROJECT_ROOT = @PROJECT_ROOT@ + +VPATH = @srcdir@ + exec_prefix = @exec_prefix@ bindir = @bindir@ libdir = @libdir@ @@ -16,10 +22,8 @@ includedir = @includedir@ manext = 1 mandir = @mandir@/man$(manext) - VPATH=@srcdir@ - # we use host compiler in this directory USE_HOST_COMPILER=yes @@ -74,4 +78,6 @@ $(ARCH)/bin2boot: $(srcdir)/bin2boot.c $(ARCH)/binpatch: $(srcdir)/binpatch.c $(CC) $(LDFLAGS) -o $@ $(srcdir)/binpatch.c $(LD_LIBS) - +Makefile: $(srcdir)/Makefile.in $(top_builddir)/config.status + cd $(top_builddir) \ + && CONFIG_FILES=$(subdir)/$@ CONFIG_HEADERS= $(SHELL) ./config.status -- cgit v1.2.3
