That was not fun. There were a variety of issues. It's needs
testing.
We use the new GENCPP for preprocessing the various scripts and config
files in config/
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.
Removed PORT_NOFORK define in favor of autotools vfork availablility
checking. Use vfork if present.
Got rid of getenv/putenv definitions in favor of including correct
system headers.
Use FD_CLOEXEC in fcntl() call rather than hardcoded '1'.
Added -lm check to configure so dtwm will build.
Renamed internal round() function to wmround() to fix warning about
redefinition of builtin.
Fixed missing backslash in Makefile.am that prevented half the sources
from building.
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.
We were building subsets of this library as archive.a objects, then
trying to combine them into a shared object. This warnings, and link
failures due to the lack of 0fPIC when building the archive libraries.
Now, we do not buld archive libraries, and the main libDtSvc.so
library is build by adding all of the .lo file in the component
subdirectories.
In a future commit, we could just remove the SUBDIR builds (DtUtil1,
etc) and build the sub objects directly.
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.
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...
