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.
First attempt at setting certain -Defines and compiler flags (like
-fno-strict-aliasing). Only linux for now.
Add CSRG_BASED to CPP_SOURCE_FLAGS rather than directly at CFLAGS.
This will be added to CFLAGS later on in the script along with other
gathered flags and options.
Set CFLAGS, CXXFLAGS, and CPPFLAGS at the end, composed of other env
variables we set earlier on.
cppfile.inc - don't set BUIT_SOURCES or CLEANFILES here as they
overwrite (or in case of the CLEANFILES +=...) ignore the settings.
Do those in the Makefile.am always.
We still need a better way to preprocess generic files. cppfile.inc
will only work for one file per Makefile...
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.
These really need to go away and are primarily used by older
unsupported platforms.
Here we fake these for Linux (4.15), freebsd (10.0), openbsd (6.2),
netbsd (8.0), and solaris (5.10).
I'm not sure about the Solaris one as I don't have any of them.
Basically, anything after Solaris 5.10, which is pretty ancient.
These should be considered temporary - all uses of these macros in the
code should be removed in favor of functionality-specific checks in
configure.
Some files were trying to access the global includes directy in the
build area with things like #include <api/c/tt_c.h>, which is now
wrong. Se we fix all of those up. tt_c.h and tttk.h are now global,
so we no longer need to root around various build dirs to find them.
TT builds again.
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...
Redo the way the main CDE libs are specified in configure.ac... The
current way could not work due to evaluation issues, and the fact that
variables like $srcdir and the like are only valid in Makefiles, not
configure.
Use @LIBNAME@ rather then $(LIBNAME) in Makefile.am files - this way
the location is always evaluated when it's run, not in configure -
which can't work for a variety of reasons.
Got some of the TT binaries to build.
Made a new include/cppfile.inc file that can be used to pre-process
files. The downside is that currently you can only pre-process one
file at a time per Makefile. Something more robust is needed, but at
least tt/bin/shell now builds. Will need to come up with a better way.
We create autotools_config.h instead of config.h to make it clear and
avoid collisions.
We use a different method to define CSRG_BASED on BSD systems, and fix
a bug in definition of XTOOLLIB.
XTOOLLIB should probably be checked out - we should get some info from
AC_PATH_X and AC_PATH_XTRA instead of hardcoding it. To be looked at
later.
