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.
Previously we would detect whether TIRPC is installed or not, and set
TIRPCINC to the include directory with the -DOPT_TIRPC macro defined.
Then, pretty much every Makefile.am needs to be sure that $(TIRPCINC) is
specified in the cpp/c/cxx flags.
Since we can never be sure that an RPC header file might be indirectly
included, a better approach is to simply add TIRPCINC to the global
list of CXXFLAGS and CFLAGS in configure.ac for everybody. This way,
it is always specified properly on tirpc systems, and we don't need to
always add it to every individual Makefile.am since everyone will get
it by default.
TIRPCLIB is still marked as a dep in libtt, so as long as libtt is
linked, you should automatically get the tirpc library too. This is
still unchanged.
For ksh, we need a full pathname. AC_CHECK_PROGS only sets the name,
so we can't use that (think of a "#!" in a shell script.
We use some shell scripting to locate the ksh pathname.
While on that subject, the current use of CPP (gcc -E) as a general
preprocessor does not work very well. I messes up whitespace,
adds/translates random whitespace, and complains bitterly about single
quotes (') in various places like comments. It's not usable for what
CDE needs.
So, now we use GENCPP. Using shell scripting like that used for ksh,
we locate the cpp program, and set GENCPP to "/full/path/to/cpp
-traditional -nostdinc". This is what Linux uses now in an Imake
build, and it works fine. We'll have to see what the BSD/Solari do.
We might need to just include BSD's "tradcpp" into the build and use
that. It too works well in limited testing, but eats blank lines. We
can live with that if we have to.
We take advantage of subdir-object and just build the subdir source
files directly as normal dependencies of libDtSvc in the top level
Makefile.am.
This means the intevening subdirectory Makefiles are no longer needed,
and no need to replicate flags and the like between the
subdirectory Makefile.am files.
Also, no need to build fake .a libs we can't really use.
configure: remove AC_OUTPUT_FILES related the the lib/DtSvc/*
subdirectories. They are no longer needed.
Static builds are disabled - there is no reason to build both shared
and static versions of everything.
MAJOR/MINOR/MICRO variables changed to CDE_VERSION_MAJOR/MINOR/MICRO.
Make DtXinerama a shared (la) library.
Add DTCLIENTLIBS SUBST to replace the role of Imake DtClientLibs, DT
libs needed to link most CDE programs.
Add AC_PROG_RANDLIB.
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.
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.
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.
