* Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1999-04-194-4/+4
| | | | | | | | | | | | | | 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). It therefore eases parsing Makefile.ins for further automatic Makefile.in conversions in future. To apply: cd <rtems-source-tree> sh <path-to>/rtems-rc-19990407-8.sh ./autogen
* Towards automake XI patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1999-03-194-12/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1999-02-181-6/+0
| | | | | | | | | | | | | This patch removes generation of targopts.h from leaf.cfg and generates it in location at score/include/rtems/score instead. To achieve this: * all rules in other Makefile.ins which have accessed targopts.h have been removed. * c/Makefile.in has been modified to generate the directories before doing anything else. I.e. to ensure the directories exist before any preinstall rule fires (This part is a bit kludgy, but it seems to work. Please check if the interaction with libhwapi still works).
* Patch from Emmanuel Raguet <raguet@crf.canon.fr>:Joel Sherrill1999-02-181-1/+9

* Patch from Emmanuel Raguet <raguet@crf.canon.fr> to add remote debug serverJoel Sherrill1998-12-032-19/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and RPC support to RTEMS. Thanks. :) Email follows: Hello, For Xmas, here is the Remote Debugger on RTEMS ! Here are 2 patches for the Remote Debugger on RTEMS for pc386 from Linux host : - one for RTEMS it self, - one for GDB-4.17. 1/ RTEMS patch -------------- This patch adds 2 libraries : - a simplified SUN RPC library - the Remote Debugger library The configuration command is the following : ../rtems4/configure --target=i386-rtemself --enable-rtemsbsp=pc386 --enable-rdbg The SUN RPC library is built only if networking is set. The RDBG library is built if networking and enable-rdbg are set. The function used to initialize the debugger is : rtems_rdbg_initialize (); A special function has been created to force a task to be in a "debug" state : enterRdbg(). The use of this function is not mandatory. 2/ GDB-4.17 patch ----------------- This patch create a new RTEMS target for GDB-4.17. The configuration command is the following : ./configure --enable-shared --target=i386RTEMS To connect to a target, use : target rtems [your_site_address] Then, attach the target using : attach 1 And... Debug ;) You can obtain the original GDB-4.17 on ftp://ftp.debian.org/debian/dists/stable/main/source/devel/gdb_4.17.orig.tar.gz This has been tested from a Debian 2.0.1 linux host.

* Patch from Eric VALETTE <valette@crf.canon.fr>:Joel Sherrill1998-07-234-396/+2
| | | | | | | | | | | | | Here is a enhanced version of my previous patch. This patch enables to potentially share the new interrupt management code for all Intel targets (pc386, go32 and force386) bsp. Note : this patch is complete only for pc386. It still needs to be completed for go32 and force386. I carrefully checked that anything needed is in for force386 (only some function name changes for IDT manipulation and GDT segment manipulation). But anyway I will not be able to test any of theses targets...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Removed CONFIG_DIR and PROJECT_HOME directories.Joel Sherrill1998-01-201-1/+1

| | | | | .align between i386-rtems (real number on .align) and i386-go32-rtems (power of 2).
* Modified a lot of files to take a first cut at supporting building fromJoel Sherrill1997-12-101-1/+4
| | | | | any directory in the build tree. The only variable which must be set before the command "gmake" is invoked is RTEMS_BSP (e.g. RTEMS_BSP=erc32).
* Fixed typo in the pointer to the license terms.Joel Sherrill1997-10-086-12/+12

* Removed include directory at "build" point and the link of this directoryJoel Sherrill1997-10-081-6/+6
| | | | | | to lib/include. Went to using a PROJECT_INCLUDE variable.
* headers updated to reflect new style copyright notice as partJoel Sherrill1997-04-227-31/+31

* Added ka9q tcpip stack and network driver for the gen68360. This effortJoel Sherrill1997-04-091-0/+9
| | | | | | | | | | | | | was done based on the 3.6.0 release and had to be autoconf'ed locally. It is turned on is the bsp enables it and it is not explicitly disabled via the configure option --disable-tcpip. As many warnings as possible were removed locally after the code was merged. Only the gen68360 and mvme136 bsps were compiled this way. The ka9q port and network driver were submitted by Eric Norum (eric@skatter.USask.Ca). The network demo programs are not included in the tree at this point.

* This set of changes is the build of what was required to convert toJoel Sherrill1997-04-011-0/+86
| | | | | | | | | | | | | | | | | | | | 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.
* Removed definitions which are now in targopts.h. This eliminates theJoel Sherrill1997-01-291-22/+0
| | | | | need for the "sed'ing" of this file. This should be a significant win when addressing non-unix host and non-gnu toolsets.
