Ticket #120
Change libtool's shared library version info to 3:0:1 to preserve the
previous library version of 2.1.0.
See https://autotools.io/libtool/version.html for the details on how
libtool handles this versioning info.
See https://verbump.de/ for a handy 'version calculator' using
libtools rules.
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.
Hardcoding a -lstdc++ is wrong, since not all OSs are likely to handle
C++ in the same way.
The issue is that libtt needs to be built as a C++ library, so we use
a fake dummy.cxx file to convince libtool to do so instead, rather
than trying to force the issue by linking a (possibly missing)
libstdc++.
Previously in the imake world, changing the CDE version required hand
editing a handful of files.
This commit makes these files into ".in" files. configure.ac now
holds CDE version information -- both in the AC_INIT() call and in the
CDE_VERSION_* variables a few lines down.
Changing the CDE version now involves editing those two locations in
configure.ac only.
Thereafter, a configure run will replace version information in the
following files with the current CDE version:
copyright
doc/common/help/HELPEnt.sgm
include/Dt/Dt.h
lib/tt/bin/ttauth/ttauth.man
This also causes a catch-22 problem with ToolTalk. So the
tooltalk.inc file is gone and the relevant TT Makefiles have been
modified to set and define the TT version in those Makefiles that
actually use it.
The arg that should be on the rhs seems to be commented out for some
reason, and assigning a variable to itself is pointless, so just
comment it out with a comment explaining why.
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.
Specifically:
- use libtool so that the top level library contains the actual
objects, and not just the sub-archives, which the linker will just
ignore.
- create the source files via symlinks rather than referencing them
with relative paths. Doing it that way causes a 'make clean' to
delete objects in DtMmdb/ which is wrong.
- fix up utility/ - it seemed to be building more source files than
the original Imakefile listed. Other changes may need to be done
here if similar mistakes were made in other subdirs.
Also, rework the way we build convenience libs for the classes to use
libtool. This fixes some potential linking issues and dependency
checking.
Next up will be to see if we can link and install it, along with it's
message catalogs, resources, etc.
