* Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1999-07-261-1/+1
| | | | | | | | | | | | | | | | | | | | | A bug in acpolish made it into rtems-rc-19990709-0.diff, which unfortunately affects all Makefile.ins: * The maintainer mode conditional was erroniously applied to the dependencies of "Makefile". In case you already checked in rtems-rc-19990709-0.diff to CVS you have to check in all Makefile.ins again after applying the patch below :). Please apply the patch below as follows: patch -p1 < rtems-rc-19990709-1.diff tools/update/rtems-polish.sh -ac Note: There is no need to rerun your tests if you have used --enable-maintainer-mode to configure RTEMS, because this patch converts all Makefile.ins to the same settings as used for --enable-maintainer-mode.
* This is part of a major patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>Joel Sherrill1999-07-261-20/+22

Finally, here they are: the "big-patch" patches - merged into one big patch (~1.5MB). Sorry for the delay, but testing took much more time than I had expected - esp. reworking the acpolish script triggered many more tiny issues than I had expected (cf. below). At least, now you've got something to spend your weekend with :-. WARNINGS: * I've gone a little (??) further than I had announced before. * Several directories have been moved. * Several files have been added and removed * I have tested it with many BSPs/CPUs and a variety of permutiations of configuration flags, but not with all. * Most parts of the patch are automatically generated, however there are many tiny manual modifications. APPLYING THE PATCH: ./autogen -c mkdir tools mv c/src/exec/score/tools tools/cpu mv c/build-tools tools/build mv c/update-tools tools/update patch -p1 -E < rtems-rc-19990709-0.diff ./autogen If the patch doesn't apply to rtems-cvs, I would suggest that you should try to apply it brute-force and then to run tools/update/rtems-polish.sh -ac -am afterwards. A recursive diff between rtems-19990709 + patch and rtems-cvs + patch then should report only a few dozen significant changes to configuration files which need to be merged manually (IIRC, I did not change any source files). *** Attention: There are files to be removed, moved, copied and added in/to CVS! NEWS/CHANGES: 1. Configuration takes place in 3 stages: 1. per host (toplevel configure script), 2. per target (c/configure), 3. per bsp c/src/configure automatically triggered from ./configure and c/Makefile.am. 2. Building of subdirectory c/ takes place in c/$(target_alias) for cross-targets in c/ for native targets 3. Building of subdirectory c/src takes place in c/${target_alias}/<bsp> for cross-targets, c/<bsp> for native targets 4. c/build-tools moved to tools/build 5. c/src/exec/score/cpu/tools moved to tools/cpu (=cpu-tools split out) 6. c/update-tools moved to tools/update 7. New subdirectory c/src/make, handles files from make/ on a per BSP basis 8. Maintainer mode support: Ie. if configuring with --enable-maintainer-mode disabled (the default), then tracking of many dependencies will be disabled in Makefiles. Esp. many dependencies for auto* generated files will be switched off in Makefiles. Ie. if not using "--enable-maintainer-mode" many auto* generated files will not be updated automatically, i.e. normal users should not be required to have auto* tools anymore (untested). 9. Independent configuration scripts for / (toplevel), tools/build, tools/cpu, tools/update, c/, c/src/, c/src/exec, c/src/lib, c/src/tests, c/src/make 10. Automake support for all directories above and besides c/src 11. "preinstall" now is implemented as depth-first recursive make target 12. host compiled tools (exception bsp-tools) are accessed in location in the build tree instead of inside the build-tree when building RTEMS. 13. RTEMS_ROOT and PROJECT_ROOT now point to directories inside the build-tree - many tiny changes as consequence from this. 14. --with-cross-host support removed (offically announced obsolete by cygnus) 15. Changing the order of building libraries below c/src/lib/ 16. Former toplevel configure script broken into aclocal/*.m4 macros 17. Newlib now detected by configure macros, RTEMS_HAS_NEWLIB removed from *cfg. 18. sptables.h now generated by autoconf 19. Rules for "mkinstalldirs temporary installation tree" moved from c/Makefile to subdirectories. 20. Cpu-tools do not get installed. 21. FIX: Use ACLOCAL_AMFLAGS instead of ACLOCAL = -I ... in Makefile.ams which are in directories with own configure scripts. 22. Hardcoding BSP names into libbsp/.../tools to avoid RTEMS_BSP get overridden from the environment. 22. FIX: Handling of MP_PIECES in various Makefiles 23. FIX: Removing "::" rules from some Makefile.ins 24. FIX: File permission chaos: (-m 444 and -m 555 vs. -m 644 and -m 755) - Now all include files use -m 644. 25. Removed many gnumake-conditionals in Makefile.ins - Partially replaced with automake-conditional, partially replaced with conditionalized Makefile variables (... _yes_V) 26. Massively reworked acpolish: acpolish now parses Makefile.ins and interprets parts of the Makefile.ins. 27. FIX: Some $(wildcard $(srcdir)/*.h) macros removed / replaced with explicit lists of files in Makefile.ins. 28. FIX: Replacing MKLIB with RANLIB in Makefile.ins 29. HACK: Add preinstallation for pc386 specific $(PROJECT_RELEASE)/BootImgs directory ... many more details, I can't recall KNOWN BUGS: 1. make [debug|profile]_install do not do what they are promissing. "make [debug|profile] install" does what "make [debug|profile]_install" has been doing. Proposal: remove [debug|profile]_install 2. Dependencies between temporary installation tree and source tree are not yet handled correctly. 3. Dependencies between temporary installation tree and source tree are handled ineffencently (Using INSTALL_CHANGE instead of make dependencies) 4. RTEMS_ROOT, PROJECT_ROOT, top_builddir, RTEMS_TOPdir now are redundant. 5. The new configure scripts still are in their infancy. They contain redundant checks and might still contain bugs, too. 6. RTEMS autoconf Makefile.ins use a mixture of configuration information gathered in c/$(target_alias)/<bsp>/make and of information collected from their configure scripts. 7. make dist is not fully functional 8. Subdirectory host-/build-/target- configure options (--target, --host, --build) do not conform to Cygnus/GNU conventions. 9. Some RTEMS autoconf Makefile.in's makefile targets are not supported in automake Makefile.ams/ins (e.g. get, clobber). 10. Some automake standard targets are not propagated from toplevel and c/Makefile.am to autoconf subdirectories (eg. make dist). 11. rpcgen generated files are not part of the source-tree (Automake conventions favor supplying generated files inside the source-tree, however there is no support for rpcgen generated files in automake, cf. yacc/lex support in automake). 12. RTEMS_HAS_RDBG handling is flaky. make/*.cfg use RTEMS_HAS_RDBG per CPU, while librdb's sources can only be built per BSP. Raises the more general question whether librdbg located correctly in the source-tree. 13. All make/*cfg files are configured per cpu, currently there is no location to store per-bsp configuration information --> bsp.cfg, per aconfig.h? 14. "make install" without having run "make all" beforehand does not work. 15. handling of --enable-multiprocessing seems to be broken in make/custom/* 16. Makefile.ins still exploit many gmake features. 17. File permisson chaos on libraries (no explict -m for libraries/rels/etc). 18. mcp750 Makefiles are broken (Note: I *do* mean buggy - I am not talking about "not-conforming to conventions", here :-). 19. Dependencies between configure scripts are not handled, eg. aborting "make RTEMS_BSP=<bsp>" can leave the build-tree in an unusable state. 20. "make clean" does not delete <build-tree>/<bsp>. This is intentional for now, because rerunning "make" after "make clean" requires an explicit "make preinstall" afterwards now. This should be done automatically, but doesn't work in this case for now. To work around this problem <build-tree>/<bsp> is kept during "make clean" for now (HACK). TODO: 1. split out host-compiled bsp-tools 2. Use Cygnus/GNU standards for cross-compiling target-subdir (CC=CC_FOR_TARGET .. configure --host=${target_alias} --build=`config.guess'}), to be added to toplevel configure script after splitting out bsp-tools. 3. Exploit per cpu support directory (c/src/<cpu>)- Splitting out per-cpu libraries - Are there any? 4. Further automake support 5. Converting subdirectories into standalone / self-contained subdirectories (Esp. moving their headers to the same common root as their sources, eg. mv lib/include/rtems++ lib/librtems++/include/rtems++) - This is the main obstacle which prevents moving further towards automake. 6. Propagating values from *.cfg into Makefiles instead of propagating them at make time via Makefile-fragments (i.e. try to avoid using *.cfg). 7. Testing on cygwin host (I *do* expect cygwin specific problems). 8. The ARCH in o-$(ARCH)-$(VARIANT) build-subdirectories is not needed anymore. GENERAL ISSUES: 1. Temporary installation tree -- Ian and I seem to disagree basically. Though I think that I understand his argumentation, I do not share it. IMO, his way of using the buildtree is mis-using the build-tree, relying on an inofficial feature of RTEMS's current implementation, which doesn't even work correctly in the current build-tree, though it attempts hard to do so. From my very POV, it unnecessarily complicates the structures of the source- and build-trees. It is not supported by automake (No automatic generation for the necessary rules) and complicates the transition to automake significantly (Generating the rules with an enhanced version of acpolish could be possible). As Ian correctly pointed out, here a management decision is needed - though I don't see the need to draw this decision in short terms. 2. preinstallation generally is a sure means to spoil the structure of the source tree, IMHO (No ranting intended, I am completly serious about this one). eg. through tree dependencies. The worst problem related to this I have found in the meantime is bsp_specs. bsp_specs is part of libbsp, ie. there is *no* way to build *any* part of the source tree *without* having a BSP *preinstalled*. Note: This issue is related to issue 1., but is not identical - The difference is the change of the order make rules have to be triggered. While preinstallation triggers rules spread all over the source tree before a "make all" can be run, a temporary installation tree could also be installed by post "make all" hooks (all-local:, to be run after make all in a directory is completed) if the directories' dependencies would be a tree, 3. Stuctural dependencies between subdirectories. 4. Depth of the source tree (Prevents multilibbing and introduces many unnecessary configure scripts). 5. per cpu vs. per bsp configuration (There are no real per-cpu parts yets :-). 6. automake does not support $makefiles in AC_OUTPUT. Unlike before, we now should try to avoid RTEMS_CHECK_MAKEFILE and to hard-code as much paths to Makefiles as possible. 7. General redesign of the source tree 8. Main installation point - Changing it to ${prefix}/${target_alias}. ? Besides item 8. (which is a must, IMHO), as far as I see most of them can not be solved soon and will remain issues in the mid- to long-term :-. REMARKS: * You (as the maintainer) should always use --enable-maintainer-mode when building RTEMS to ensure that maintainer mode generated files (esp. those in c/src/make) will be updated when make/* files have changed. * Use @RTEMS_BSP@ in Makefile.ins and Makefile.ams below c/src/, $(RTEMS_BSP) or ${RTEMS_BSP} will be overridden from environment variables when using make RTEMS_BSP="....". * c/src/make is a temporary cludge until configuration issues are solved. At the moment it is configured per bsp, but contains per-target/cpu info only. Its main purpose now is to circumvent modifying make/*.cfg files, because I consider make/* to be frozen for backward compatibilty. * This patch should only affect configuration files. At least I do not remember having touched any source files. * To build the bare bsp you now need to mention it in --enable-rtemsbsp. Example: building gensh1 and sh1/bare simultaneously: ../rtems-rc-19990709-1/configure --target=sh-rtems \ --enable-rtemsbsp="bare gensh1" \ --prefix=/tmp/rtems \ --enable-bare-cpu-cflags='-DMHZ=20 -m1 -DCPU_CONSOLE_DEVNAME=\"/dev/null\"' \ --enable-bare-cpu-model=sh7032 \ --enable-maintainer-mode \ --enable-cxx make make install * The next steps in development would be to split out bsp-tools and then to change to Cygnus/GNU canonicalization conventions for building the c/ subdirectory afterwards (i.e. many standard AC_*.m4 macros could be used instead of customized versions) FINAL REMARK: The issues mentioned in the lists above sound much worser than the situation actually is. Most of them are not specific to this patch, but are also valid for the snapshot. I just wrote down what I came across when working on the patch over the last few weeks. I wouldn't be too surprised if you don't like the patch at the current point in development. I am willing to discuss details and problems, I also have no problem if you would post-pone applying this patch to times after 4.1, but rejecting it as a whole for all times would be a false management decision, IMHO. Therefore I would suggest that you, if your time constaints allow it, should at least play a little while with this patch to understand what is going on and before drawing a decision on how to handle this proposal. I know this patch is neither perfect nor complete, but I consider it to be a major breakthrough. Don't be anxious because of the size of the patch, the core of the patch is rather small, the size is mainly the side effect of some systematic cleanups inside the Makefiles (result of acpolish). Feel free to ask if you encounter problems, if you don't understand something or if you meet bugs - I am far from being perfect and am prepared to answer them.

| | | | | | | | | | | | | | This one is an enhancement to acpolish. It replaces some Makefile variables by others variable in Makefile.ins (tries to use unique name for some variables).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <source-tree> patch -p1 -E < <path-to-patch>/rtems-rc-19990318-1.diff tar xzvf <path-to>/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.
* Towards automake X patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1999-03-191-0/+5
| | | | | | | | | | | | | | | | | | | This one once again changes the scheme to preinstall bsp_specs. It moves generating PROJECT_ROOT/lib/bsp_specs to libbsp/<cpu>/<bsp>/wrapup/Makefile.in. I.e. it decentralizes generation of bsp_specs to a bsp-dependent directory, because preinstalling bsp_specs in a centralized Makefile like it has been done until now does not harmonize well with spliting the toplevel configure script in cpu and bsp-dependent configure scripts and automake. First apply the patch (rtems-rc-19990318-0.diff) below, then run the reorg-bsp_specs.sh script. IMO, this one is comparatively harmless and eases automake support significantly.

* Big patch form Ralf Corsepius described in this email:Joel Sherrill1998-01-301-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here is the result of my nightly work to get RTEMS_ROOT=$srcdir working with different shells and relative/absolute paths. What I did is relatively simple in principle: Instead of setting RTEMS_ROOT in configure.in and then let configure substitute @RTEMS_ROOT@ inside the Makefiles, I now let each Makefile set RTEMS_ROOT from each Makefile's @top_srcdir@ value. The difference is subtile, but with enormous side effects: - If RTEMS_ROOT is set in configure, then the same single value will be propagated to all Makefiles. This breaks using relative paths, as the relative path to the root of the source tree is used inside of all subdirectory Makefiles. - Now each Makefile.in sets RTEMS_ROOT = @top_srcdir@. top_srcdir is computed individually by configure for each single Makefile.in, hereby receiving the correct value, no matter if relative or absolute paths are used. To get this working, I needed to remove setting RTEMS_ROOT from target.cfg.in, because this overrides the value of RTEMS_ROOT from each individual Makefile. Furthermore, I removed RTEMS_CUSTOM from the Makefiles and replaced all "include $(RTEMS_CUSTOM)" directives with"include $(RTEMS_ROOT)/make/custom/$(RTEMS_BSP)". Perhaps you don't like this, but I think, to have one variable less is clearer and easier to understand than having several variables refering to the next one. I enclose a small patch to this mail, which - fixes the config.h problem (to finally clearify misunderstands) - removes assignment/subsitution of RTEMS_ROOT from configure.in - contains a workaround for the application Makefile's RTEMS_ROOT problem (reported by Eric) - removes some unused lines from the toplevel Makefile.in - removes assignment of RTEMS_ROOT from make/target.cfg.in

* This set of changes is the build of what was required to convert toJoel Sherrill1997-04-011-0/+48
GNU autoconf. This is the first large step in allowing an RTEMS user to perform a one-tree build (per crossgcc FAQ) including RTEMS in the build process. With this change RTEMS is configured in built in the same style as the GNU tools, yet retains the basic structure of its traditional Makefiles (ala Tony Bennett). Jiri Gaisler (jgais@wd.estec.esa.nl) deserves (and received) a big thank you for doing this. There are still issues to be resolved but as of this commit, all target which can be built on a linux host have been using a modified version of the source Jiri submitted. This source was merged and most targets built in the tree before this commit. There are some issues which remain to be resolved but they are primarily related to host OS dependencies, script issues, the use of gawk for hack_specs, and the dependence on gcc snapshots. These will be resolved.
