Incorporated automake I patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:
This is the first real automake patch. It adds automake support to c/build-tools and cleans up a few minor issues. I consider this to be a testing probe to examine problems with automake. Therefore, this patch is just a more or less harmless replacement of the former RTEMS Makefiles and I expect it not last for long. If you want to give automake Makefiles a public try and if you want/need to learn about problems with it, then it's about time for a new snapshot, IMO. I may have screwed up something not directly related to automake, but I expect very few (none to be precise) problems with automake. However, somebody should at least try building on Cygwin. If you feel a bit more adventureous, then I also can continue to submit more patches. [FYI: I still have a couple of automake files laying around, but they need some cleanup before being submitted as patches. Now, that I am just into it, I'll perhaps submit another one tonight :-] After applying this patch (patch -p1 -E < <path-to>/rtems-rc-19990318-0), first run the "autogen" script from the toplevel source directory, before committing to CVS. Be careful about dependencies between Makefile.am and Makefile.ins when cutting tarballs from CVS. Makefile.ins are required to be newer than Makefile.ams, otherwise users would need to have automake, autoconf and perl. Some people recommend to "touch" all Makefile.in after checkout from cvs (cf. egcs/contrib/egcs_update). ATTENTION: * This patch adds a number of new files. * remove aclocal/exeext.m4 and aclocal/cygwin.m4 from CVS, They are now covered by autoconf-2.13`s AC_EXEEXT. Some features/side-effects which are probably interesting for you: In a configured build-tree "cd c/build-tools", then try * "make RTEMS_BSP=<bsp> install" * "make RTEMS_BSP=<bsp> dist"
