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.
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.
These are just minor tweaks to make sure the 'make install' part does
what it is supposed to do. I also removed some commented code in the
dtmail Makefile related to SunOS, as that is not currently suppoerted
anyway.
Many of these were real bugs, like:
if (cond);
do_something
etc...
Others were just cosmetic - like placing the ';' on a separate line to
make the intention clear.
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.
Make -lXinerama a dep on libDtXinerama so it doen't need to be
specified in Makefile.am files or in LIBS as it was being done
previously.
This still needs a little work, ideally Xinerama should be completely
optional and only enabled if present. But we can save that for
later.
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.
At this stage, these certainly won't actually build yet.
Just fix up the relevent Makefile.am files so that autogen does not
emit errors and warnings for them.
Removed AIX/HPUX support in Makefile.am files. No point in
propogating that stuff when we've already removed much of that
unmaintained code from the codebase.
Commented out all of the Sun Pro stuff. Someone whos using that will
need to go through and fix it. This is mostly in dtmail and dthelp.
In fact, someone who does Solaris in general will need to go through
this stuff.
Next up, we'll replace any remaining 'if SUN' conditionals with 'if
SOLARIS' which is a more appropriate name and was already defined in
configure.ac.
Then we'll see about getting these new directories building.
While CDE builds fine with gcc6 on FreeBSD 11, the default clang build
was broken in a few places. This commit allows CDE to build now using
the default clang 6 system compiler.
