1. Finally fixes raw interrupts for pc386
2. Makes some minor cleanup in console and startup
3. Makes rtems_termios_dequeue_characters() to return count of
outstanding chars - it allows to simplify console isrs a little
bit.
4. pc386 uart modified to be friendlier to termios parameter changes,
to have minor performance improvement and to take advantage of
of above termios modification.
I have managed to build the bsp ods68302 and the rtti test case I made
with egcs-1.1b and binutils-2.9.1.
I have built our C++ application and got no link errors so it looks like
this is now working. I am yet to test the code but getting the thing to
link was the problem.
Please find a patch attached which removes the -fno-rtti option.
The patch (rtems-rc-980821.diff) I had sent recently to fix the "make
install" problem in rtems-980821/make/ still contained a bug (Thanks to
Eric N. for reporting it).
The patch enclosed to this mail is a corrected version of this patch,
which finally should fix this problem.
Here is another patch to hopefully enhance rtems' configuration.
Motivation: Try to support other c-compilers besides gcc (I tried to
build rtems under Solaris using sun's WSPro c-compiler).
Here is a couple of small patches concerning the host compiler
configuration, which fix/work-around the worst problems when using sun's
WSPro c-compiler.
Changes:
* Replaced make/compilers/gcc.cfg with make/compilers/gcc.cfg.in, ie.
gcc.cfg is generated by configure now.
* Removed a line containing a hard-coded "gcc" from gcc.cfg (BUG-fix).
* Add -g to host compiler flags only if configure reported -g to work
* Add -Wall to host compiler flags only if configure reported that the
host compiler is gcc (WSPro's cc chokes on -Wall).
* Some modifications to make/Makefile.in
* Adapted make/custom/default.cfg to the new location of gcc.cfg
BTW, gcc.cfg/gcc.cfg.in seems to be full of unused code (DEBUG-VARIANTS
etc.) which deserves to be cleaned up, IMO.
IMO, a similar patch should be applied to gcc-target-default.cfg
make solaris target buildable.
> 1. The ipc check fails since solaris does not define union semun.

BSDINSTALL is defined in make/host.cfg.in as
BSDINSTALL=@INSTALL@
@INSTALL@ is generated by autoconf's standard macro AC_PROG_INSTALL, which
is widely used in almost any autoconf/automake configured package. In case
there is really something wrong with it, then it must be considered a bug
in autoconf.
I can see a doubious fragment in AC_PROG_INSTALL, which is used when no
appropriate bsd-install is found.
Finally Ralf saw a problem with the find on solaris which I also saw and
fixed.
Here is a patch for KA9Q stack.
This patch contains an Ethernet Driver for Western Digital,
some fixes for the UDP and TCP protocols (for endian conversion)
and some little programs which allow the test of UDP and TCP
sockets via Ethernet.
I have tested that on an Intel machine. If someone can test it
on a big-endian machine, ...
* Added support for bsd "install" ($(BSDINSTALL)) to host.cfg.in, i.e.
the standard "install" program that most packages (including automake)
use. In Makefiles outside of rtems, "install" normally is referenced by
$(INSTALL), but rtems already uses $(INSTALL) for install-if-change,
hence I used $(BSDINSTALL) instead to keep up backward compatibility.
* Removed references to @GREP@ etc. from host.cfg.in, as configure.in
doesn't check for them (Minor cleanup).
* Added installation flags INST*FLAGS to host.cfg.in, which should
replace -m XXXX flags for installation calls.
*Changes to gcc.cfg to enable it to build host programs from multiple
sources files.
Should not disturb existing sources, but neccessary.
* There was a not-so-minor bug in the configuration files: "make
install" and "make debug_install" don't work in all subdirectories!! I
tried to fix this by adding "install" to MTARGETS in main.cfg, which
seems to solve most of the problems. But there still seem to be rare (?)
cases where "make debug_install" still seems to have problems.
* Changes to many host related tool-Makefiles to demonstrate the
abilities of INST*FLAGS, BSDINSTALL and the new rules in gcc.cfg.
..of cause ... but BSDINSTALL is THE standard method to install files
in most program packages besides rtems. This part of the patch fixes
some minor protection setting problems, but doesn't support
TARGET_VARIANTS
NOTE:
I hope you will like the BSDINSTALL, INST*FLAGS stuff. It is a step to
get rid of "install-if-change" and to rely on a more standard
installation procedure. If you don't like BSDINSTALL, removing it from
the patch isn't difficult- just grep for BSDINSTALL and replace
BSDINSTALL with INSTALL or MKDIR.
FINALLY:
I still have another patch pending (well, not a complete patch yet, it's
a partial patch to demonstrate the principle), which adds automatic
rebuilding of files generated by autoconf/configure. At the moment I
don't dare to submit it, because integrating this patch would require to
modify all Makefile.ins because we'd need to add a new "include " line
to each Makefile.in.
<corsepiu@faw.uni-ulm.de> and his comments are below:
Joel, obviously you did apply my previous patch to
gcc-target-default.cfg -- This should have been gcc.cfg
(gcc-target-default.cfg should NOT contain any EXEEXT).
> It seems that rules for %{EXEEXT} don't exist in gcc-target-default.cfg
No, gcc-target-default.cfg is used to compile executables for the target
only, not for the host.
EXEEXT may only be used for programs to be run on the host.
> What should I add please?
This was a bug in my initial configuration patch to rtems-980616. A
correction to this patch I had sent to Joel at 26.06.98 doesn't seem to
have made it into the snapshot.
Please find attached the patch I had sent to Joel, hopefully this patch
fixes this problem.

made no attempt to divide the comments up and place them with just
the appropriate files. Here is an excerpt from Ralf's email:
Changes including comments on changes I made after cycling through
all the targets:
* Added ranlib support. Now all targets use "ranlib" instead of "ar -s"
to build an index for a library. If ranlib isn't detected during
configuration, check if ar -s is working and try "ar -s" instead of
* Removed $(XXX_FOR_TARGET) from make/target.cfg.in, use $(XXX) instead now.
* gcc-target-default.cfg: LINK_XXXX-defines reworked to solve the -l
problem under posix (cf gcc-target-default.cfg)
* rtems-glom replaced by Makefile-rules inside of the wrapup/Makefile.in
that has been using rtems-glom until now.
* Removed CCC and friends in gcc-target-default.cfg, as they have been
breaking CXX support.
* Removed CONFIG.$(TARGET_ARCH).CC lines from several custom/*.cfg
files, because this is now set in custom/default.cfg.
* Added aclocal/ar-s.m4, check whether "ar -s" is working
* Added aclocal/cygwin.m4 and aclocal/exeext.m4.
* Reworked aclocal/canonicalize-tools.m4: Added ar -s check; fixes for
problems when XXX_FOR_TARGET is given via environment variables (didn't
work for gcc until now), adding cygwin check, improved autoconf-cache
handling.
* Removed -l from make rule dependencies. LINK_LIBS is now allowed to
contain -L and -l. LINK_OBJS and LINK_FILES must not contain -L or -l.
gcc28 make-exe rules now link using $(LINK_OBJS) $(LINK_LIBS) => Almost
all custom/*.cfg are modified. This is very likely to break something
because of typos or having missed to edit a file.
Open problems, known bugs, things I didn't do:
* custom/p4000.cfg seems to be out of date and requires to be reviewed.
(JRS NOTE: It is subordinate p4650 and p4600 -- both of which build ok
after minor changes.)
* custom/psim.cfg needs to be reviewed, I added some changes to it, I am
insecure about.
(JRS NOTE: psim had a minor problem endif/endef swapped but runs fine.)
* rtems-glom.in can now be removed.
* gcc*.cfg files "make depend" rules don't honor language specific flags
(e.g CXXFLAGS is ignored for *.cc) - Nothing to worry about now, but may
cause problems for hosts/targets not using gcc or rtems-add-ons that use
external packages.
* AFAIS, the no_bsp BSP can't be build anymore, i.e. configure refused
to configure for it whatever I tried.
* The toplevel and toplevel+1 README files are quite out-dated
* cygwin.m4 isn't of much use for rtems. In most cases (cf.
aclocal/*.m4) it is worked around by directly using $host_os. I think
I'll remove it soon after the next snapshot
* Before release the cygwin patch needs to be tested under cygwin. I may
have broken/missed something (esp. the sed-pattern to convert \\ into /
may be broken).
* You should try to build/run the posix-BSP under solaris - I don't
expect problems, but I am not 100% sure, esp. with regard to ranlib/ar -s.
* You should consider to convert all make/compilers/*.cfg files into
make/compilers/*.cfg.in files and let autoconf generate the *.cfg. This
may help getting rid of some if/then/else statements and help
hard-coding some defines into those files in future and shouldn't
disturb now.
* Not having installed libc.a/libm.a on a host may still break building
rtems, esp. when using -disable-gcc28 as the gcc27-configuration scheme
directly accesses libc.a and libm.a. The problem should not appear when
using gcc28 because it references libc/libm only through -lc and -lm
which may be static or dynamic (I didn't test this).
* shgen is not yet included (I didn't yet have enough time to integrate it).
* I know about a few more configure-probs (esp. cross-checking
--enable-* flags).
+ warn/refuse to configure when --enable-libcdir and
--enable-gcc28 are given.
+ force --enable-libcdir when --disable-gcc28 is given
* Replaced KSHELL with @KSH@ in some shell scripts generated by configure.in.
* Added a dependency to aclocal/*.m4 in the toplevel Makefile => configure
and aclocal.m4 will now be rebuild when any aclocal/*.m4 file is changed
* Some changes to aclocal/gcc-pipe.m4 and aclocal/gcc-specs.m4
* Replaced i[[3456]]86-unknown-freebsd2.[[12]] with i[[3456]]86-*freebsd2.*
in configure.in, as I suppose there might exist a variety of valid vendors
(2nd field of the name-tripple)
* Disabled override MAKEFLAGS in toplevel Makefile.in - Potential
side-effects are not really clear to me.
* In mvme162.cfg, $(LINK_LIBS) is missing in the CC line in gcc28's make-exe
rule (yet another one I missed to edit). Just append $(LINK_LIBS) to
the "CC" line, like I hopefully did to ALL other custom/*.cfg files.
* the problem with mvme162lx.cfg is a follow-up problem of the
mvme162.cfg-bug.
* mvme162/console and idp/console had variables named Buffer which
conflicted with similarly named variables in some tests.
