* Modified to avoid conflicts on definitions of malloc. newlib 1.8.2Joel Sherrill1999-10-063-3/+3
| | | | | | | | now prototypes the malloc family in stdlib.h. This causes conflicts with the way the network stack overrides the definitions of malloc. As best I (being Joel) can tell, commenting stdlib.h out keeps the files compiling and referencing the desired malloc/free but results in more warnings.

* Removed targets and configurations that are no longer functionalJoel Sherrill1999-10-053-33/+0
| | | | | | | | | | | | | | and not likely to become so. Comments on each configuration are below. + Force CPU386 - This BSP was developed as part of the initial port of RTEMS to the i386. This board has been unavailable for a long time now. + GO32 - This BSP and some CPU code supported djgpp v1.x. This version is now quite old. No one has stepped forward to update the code to v2.x which may be technically impossible anyway. More importantly, go32 has been superceded by the pc386 BSP.
* Patch from Wayne Bullaughey <wayne@wmi.com>. Comments follow:Joel Sherrill1999-10-051-1/+1
| | | | | | | | | | | | I'm working on code to mount my host based file system on the base file system (imfs) and have a suggestion for a change to eval.c in the c/src/lib/libc directory of the 8/20/1999 snapshot. The current version does not test the result value returned from the evalpath callback (line 47) in the case where follow_link is true. Attached is my suggested change. Without this test the node_type callback may be called after evalpath failed. node_type could set the type to some value other then RTEMS_FILESYSTEM_HARD_LINK or RTEMS_FILESYSTEM_SYM_LINK but it seems cleaner to add the check on result.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch below actuallly consists of two patches: 1) moving librpc to c/src/librpc similar to what has been done to librtems++ 2) reworked configure scripts, many safety and dependency checks added to aclocal/*.m4 macros + configuration fixes.

* Patch from Jimen Ching <jimen@adtech-inc.com>:Joel Sherrill1999-08-181-0/+45
| | | | | | | | | | | | | | | Please take a look at this new patch. It contains a cleaner implementation of the reset operation. These patches are against 4.0.0. But the files did not change from the 3.6.0 release. Also, the cpu.h patch below still applies. I.e. instead of using i960ca_PRCB, use i960_PRCB. Explanation: The previous patch removed the use of the reset instruction, because it always fails. But this was due to the fact that some of the registers were corrupted by the re-init procedure. The new patches save and restore those registers when a re-init is done.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Here is another fix, which addresses a few more or less severe bugs in configuration and unix/posix: * Configuration fix: c/src/lib/configure.in didn't handle RDBG correctly * Configuration fix: make depend was non-functional in c/src/lib/libc/Makefile.in * Configuration fix: stray comment removed from aclocal/target.m4 * RTEMS fix: termios support for unix/posix now uses the host's headers only (was completely broken). - Don't install RTEMS's newlib sys/termios.h for unix (sys/termios.h apparently is a newlib specific header) - To be able to compile RTEMS's termios.c with glibc2.1, glibc-2.1 needs __USE_MISC, which is a private define from gcc's features.h, being defined only when _BSD_SOURCE of _SVID_SOURCE is defined. RTEMS's termios apparently implements BSD, thus -D_BSD_SOURCE was added to Linux-posix.cfg. - Conflicting definitions for __USE_MISC and _BSD_SOURCE inside of RTEMS codes removed due to definition of _BSD_SOURCE on the toplevel. This fix has been tested with linux/posix (primary glibc2.1 native), linux/posix (secondary libc5 native), sh/gensh1, i386/pc386 and a couple of other bsp's/CPU.

* Patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:Joel Sherrill1999-08-121-14/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After upgrading my linux box to the brand new SuSE 6.2 release, which is glibc-2.1 based, I came across a bug in RTEMS - IIRC, I even warned you about it about 1/2 a year ago, but nothing has been done since then :-. The *.m4 macros to check for SYSV/IPC are broken for linux/glibc2.1, because they assume that linux always defines union semun, which isn't true anymore for glibc2.1 (the manpage for semctl states _X_OPEN specifies it this way). Therefore I have tried to implement a more general approach for handling SYSV for unix/posix which checks for presence of struct semun, instead of trying to evaluate OS specific preprocessor symbols. This approach is a bit adventureous, because I only tested it with linux/glibc2.1 and linux/libc5, but not under other Unix variants RTEMS supports. I am quite confident it will work on other hosts, too, but who knows :-. [FYI: I think this might also is the cause of some problems with RedHat 6.X / Mandrake linux recently reported on the rtems list -- rtems-4.0.0 can not be build for posix on any glibc2.1 based host] Furthermore the patch below contains a couple of minor fixes and configuration cleanups, which IMO should be applied before releasing a new snapshot. To apply this patch: cd <source-tree> patch -p1 < rtems-rc-19990709-8.diff ./autogen

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.

* Patch from Eric Norum <eric@cls.usask.ca>:Joel Sherrill1999-07-121-20/+15
| | | | | | | | | | | | | | I get the following warning when compiling the latest snapshot. I had a quick look at the source -- it certainly looks to me like this is a real bug. ../../../../src/rtems-19990709/c/src/lib/libc/mount.c:97: warning: `options' might be used uninitialized in this function Also, I changed the TFTP test program and TFTP driver to reflect the changes in the way paths are passed to the TFTP driver. The TFTP driver now needs a proper `dotted-decimal' hostname as the second component of the path name.
