This has meant very little for a long time as configure.ac just
hardcoded these values depending on the current OS versions at the
time.
The only place where this is really 'needed' is XlationSvc.c in DtSvc
so that differences between locale specifications on various versions
of an OS can be accounted for. So for now, we just define those when
building DtSvc.
We could probably safely remove them as well with an update to the
Xlate locale DB to remove ancient cruft we don't care about anymore.
For various other modules, like dtlogin, dtsession, etc we just use
the code that was already being used due to the hardcoded values we've
had for the last 10-ish years.
OS_VERSION was used with a '#if defined(sun)', but since it was never
set anywhere it just omitted that block. If the block turns up to be
broken on sun systems, then someone will fix it properly.
Previously we would fail in some parts of the code if we did not have a
premade configuration, now we use any code that was marked as Linux, BSD and
Solaris as our basis in order to support building unknown Unix systems.
Ticket #120
Change libtool's shared library version info to 3:0:1 to preserve the
previous library version of 2.1.0.
See https://autotools.io/libtool/version.html for the details on how
libtool handles this versioning info.
See https://verbump.de/ for a handy 'version calculator' using
libtools rules.
Hardcoding a -lstdc++ is wrong, since not all OSs are likely to handle
C++ in the same way.
The issue is that libtt needs to be built as a C++ library, so we use
a fake dummy.cxx file to convince libtool to do so instead, rather
than trying to force the issue by linking a (possibly missing)
libstdc++.
Previously in the imake world, changing the CDE version required hand
editing a handful of files.
This commit makes these files into ".in" files. configure.ac now
holds CDE version information -- both in the AC_INIT() call and in the
CDE_VERSION_* variables a few lines down.
Changing the CDE version now involves editing those two locations in
configure.ac only.
Thereafter, a configure run will replace version information in the
following files with the current CDE version:
copyright
doc/common/help/HELPEnt.sgm
include/Dt/Dt.h
lib/tt/bin/ttauth/ttauth.man
This also causes a catch-22 problem with ToolTalk. So the
tooltalk.inc file is gone and the relevant TT Makefiles have been
modified to set and define the TT version in those Makefiles that
actually use it.
Such environments are missing void type, older K&R C, and
such supports already had been removed in various places.
Furthermore, current hardcoded 'SIGNALRETURNSINT' is wrong.
This commit will not completely remove all Imake files, specifically
those for sections that have not been completed yet.
Also, the databases dir has been moved to databases-delete-later until
we have everything building and installed properly.
CDE has relied upon catgets() implementations following a relaxed
interpretation of the XPG internationalization standard that ignored
-1, the standard error value returned by catopen, as the catalog
argument. However, this same behavior causes segmentation faults with
the musl C library.
This patch:
- Centralizes (with the exception of ToolTalk) all calls to catopen(),
catgets(), and catclose() through MsgCat within the DtSvc library.
- Prevents calls to catgets() and catclose() that rely upon
undefined behavior.
- Eliminates a number of bespoke catgets() wrappers, including multiple
redundant caching implementations designed to work around a design
peculiarity in HP/UX.
- Eases building CDE without XPG internationalization support by providing
the appropriate macros.

With this patch, CDE (autotools) builds and runs on fbsd 12 now.
fbsd11 should work too, but not yet tested.
You must use gmake - ie:
./configure MAKE=gmake
gmake
Seems all of the BSD's will need to use gmake for now.
Certain programs like dtlogin and tt_type_comp need access to the
system's cpp command to process certain files at runtime. tradcpp is
not installed on most systems, and is intended for use as a imake-cpp
replacement which is all we are using it for. We still need an
honest cpp for the CDE components to use.
Now, we look in various places for a 'cpp' command and set CPP_COMMAND
to it's value. This way tt_type_comp and other CDE programs can do
required processing at runtime.
There is a problem with CPP_PROGRAM - using $CPP or $GENCPP (tradcpp)
always fails in tt_type_comp with the error:
"nclude ", line 8: syntax error
If I define it to /lib/cpp (previous hardcoded value) then it seems to
work fine. Only the dtinfo and dtinfo_start ptypes use #include, and
therefore show this error. Needs investigation.
Also, restructure some of the dependencies in the lib/tt binaries. We
will link with libtt (which will include libtirpc as a dependency),
and XTOOLLIB - all the right X11 stuff without needing to add it to
every OS. Removed several uneeded OS specializations ("if LINUX",
etc) as a result.
