With this patch, CDE (autotools) builds and runs on fbsd 12 now.
fbsd11 should work too, but not yet tested.
You must use gmake - ie:
./configure MAKE=gmake
gmake
Seems all of the BSD's will need to use gmake for now.
1. On OpenBSD, and check is made for only bison or byacc. yacc is
present, but not usable apparently. So - need to install bison on the
BSD's.
2. the libjpeg.h check fails as it is located in a non-standard
location (/usr/local) on BSD systems. Just remove the check for now
until we have a better way to check that stuff (like X11 and Xm
headers too).
A list of major things like ksh, cpp, etc are saved in a list if they
are not found. If this list is non-empty when configure is nearly
done, an error message is displayed listing the missing programs.
This is less annoying than stopping after every missing programs.
Also, removed the X11/Xm header checks for now. Those need to take
into account X_CFLAGS in some way since these files are located in
dirfferent areas on different OS's (obsd puts them in
/usr/X11R6/include for example).
... and move the PROG_CC and PROG_CXX checks toward the beginning.
Without the move the compiler search arguments are ignored. We search
for 'cc gcc clang' and 'c++ g++ clang++', in that order for CC and CXX
respectively.
This means there should be no need to override the CC
and CXX variables on the configure command line for BSD systems.
On OpenBSD for example, cc links to clang. On Linux, cc links to
gcc. You can still override these if you like with CC=... and
CXX=... on the configure command line.
gmake (MAKE=gmake) still needs to be used on the BSD's though.
With these and previous changes, CDE builds, installs, and runs
correctly on OpenBSD 6.5 now.
With this commit, CDE can install and run now. There are still some
programs/ that are not yet built:
dthelp dtksh dtappbuilder dtdocbook dtinfo nsgmls ttsnoop
and of course documentation (doc/). But this is a great start. For
the first time, things build, install, AND run correctly :)
Use a common make include file to do most of the work and set the
appropriate LANG from localized/templates/ . This should simplify it
quite a bit and reduce duplication.
Also we were not even installing them, so now we are.
Certain programs like dtlogin and tt_type_comp need access to the
system's cpp command to process certain files at runtime. tradcpp is
not installed on most systems, and is intended for use as a imake-cpp
replacement which is all we are using it for. We still need an
honest cpp for the CDE components to use.
Now, we look in various places for a 'cpp' command and set CPP_COMMAND
to it's value. This way tt_type_comp and other CDE programs can do
required processing at runtime.
There is a problem with CPP_PROGRAM - using $CPP or $GENCPP (tradcpp)
always fails in tt_type_comp with the error:
"nclude ", line 8: syntax error
If I define it to /lib/cpp (previous hardcoded value) then it seems to
work fine. Only the dtinfo and dtinfo_start ptypes use #include, and
therefore show this error. Needs investigation.
For some reason, whenever OSMajorVersion was >= 2 (this equates to a
2.x kernel or above), yacc would be used instead of bison.
On Ubuntu, and probably other linux systems, yacc is just a shell
wrapper around bison, so let's just use that directly.
These use the 'merge' utility which hardcodes temp files and the like
- it cannot be run with other instances without generating bogus
errors and occasionally coredumping. :(
There are still some issues here - specifically with the C
dtbuilder/dtcodegen catalogs. They may be broken due to dtbuilder not
being built yet.
Also, once dtinfo can be built, the msgs and app-defaults for it
should be re-enabled.
I also see gencat coredumping in localization/ while doing a multicore
(-jX) make. Regular single core builds seem to work fine.
One-off error:
Old buffer length was 6 for one character (3 * 1 + 3)
We need one more byte par character in the buffer for
the hex representation of it.

tcl combined with RCHECK will abort because memory blocks
are allocated contiguously and we overwrite the magic marker
of the next block.
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.
Also, restructure some of the dependencies in the lib/tt binaries. We
will link with libtt (which will include libtirpc as a dependency),
and XTOOLLIB - all the right X11 stuff without needing to add it to
every OS. Removed several uneeded OS specializations ("if LINUX",
etc) as a result.
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.
