Undefine USE_XFT so Motif 2.3 doesn't pull in Freetype
CDE included Freetype and Xft solely to satisfy builds of Motif with
Xft support enabled. However, as CDE only supports bitmap fonts, this
dependency was entirely superfluous and unnecessarily broke backwards
compatibility with older systems.
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.
There are/were two dproto.h files, one in DtSearch, one in raima. The
one in raima is the one we want, so replace the global Dt/dproto.h
with it. Also correct a prototype declaration error in that file.
Delete the dproto.h file in DtSearch, it's garbage and unused.
Next, redo the way yacc is used. Autotools does "the right thing" by
simply including the .y file in *_SOURCES and using
BUILT_SOURCES/CLEANFILES to manage it. No need for special rules to
handle yacc and lex.
Ok - so one of the steps in building CDE is an early phase called the
includes phase (make includes). At this point, all of the public
header files are exported to exports/include/Dt, DtI, ...
Then, the software is built using that include dir.
This of course does not work in autotools. Much of the software does
things like #include <Dt/something.h>, so in order for the build to
succeed, this behavior must be represented/replicated in some way.
It seems the usual way of dealing with this is to place all public
headers (and in some projects, ALL headers) into a toplevel include
directory.
We now do this for all public headers - they have been moved from
wherever they were and placed in the appropriate spot in includes/
This will break the Imake 'make includes' phase unless the Imakefiles
are fixed (remove the HEADERS = stuff, and the incdir defines). This
has not been done at this point since in reality, once autotools works
properly, there will be no need for the Imake stuff anymore, and I
intend to get rid of it.
This is just a warning for now - Imake builds in this tree will now
fail at the 'includes' stage.
This commit is only the migration. In upcoming commits, libtt will be
fixed so that the hack being used before to get around this problem is
removed as there will no longer be any need.
And then the autotools work continues...
