Build feedback filtered by a script which filters out -Dthis -Wthat:
gcc -g -I../include -I../lib/lua-/src -c ../win/share/tilemap.c
The second -I is obsolete or else its bogus value would have caused
build failure. When removing it, I noticed that there was still quite
a bit of obsolete yacc and lex stuff in there. Remove that too.
Unix Makefile.utl wasn't aware of the dependency of makedefs.o on
src/mdlib.c so didn't rebuild makedefs when it should have.
Eliminate several warnings:
mdlib.c - #if inside the arguments to macro Sprintf();
nhlua.c - nhl_error() ends with a call to lua_error() which doesn't
return, but neither of them were declared that way;
nhlsel.c - because of the previous, the 'else error' case of
l_selection_ellipse() led to complaints about uninitialized
variables;
sp_lev.c - missing 'const'.
I did minimal testing which went ok, but revisiting a couple of levels
gave me un-freed memory allocated by restore.c line 1337. (I haven't
looked at that at all.)
Game is playable, and should compile on linux and Windows.
Assumes you have a lua 5.3 library available.
Removes level compiler and associated files.
Replaces special level des-files with lua scripts.
Exposes some NetHack internals to lua:
- des-table with commands to create special levels
- nh-table with NetHack core commands
- nhc-table with some constants
- u-table with some player-specific data (u-struct)
- selection userdata
Adds some rudimentary tests.
Adds new extended command #wizloadlua to run a specific script,
and #wizloaddes to run a specific level-creation script.
nhlib.lua is loaded for every lua script.
Download and untar lua:
mkdir lib
cd lib
curl -R -O http://www.lua.org/ftp/lua-5.3.5.tar.gz
tar zxf lua-5.3.5.tar.gz
Then make nethack normally.
Make some progress on a couple of next minor release checklist
items, hopefully without introducing too many new bugs. This
is just the initial commit, and work continues.
Checklist items:
Savefiles compatible between Windows versions, whether 64-bit
or 32-bit in little-endian field format.
Selection of file formats:
historical (structlevel saves),
lendian (little-endian, fieldlevel saves),
and just for proof-of-concept, ascii fieldlevel saves
(the ascii is huge! 10x bigger than little-endian).
For the fieldlevel save, all complex data structures recursively
get broken down until until it is one of the simple types that
can't be broken down any further, and that gets when it gets
written to the output file.
New files needed for this build:
hand-coded:
include/sfprocs.h
src/sfbase.c - really a dispatcher to one of the
output/input format routines.
src/sflendian.c - little-endian output writer/reader.
src/sfascii.c - ascii text output writer/reader.
auto-coded (generated):
include/sfproto.h
src/sfdata.c
This is just one approach. I'm sure there are countless others
and they have different pros and cons.
For producing the auto-coded files a utility called
universal-ctags, that is actively maintained and evolving,
was used to do all the heavy-lifting of parsing the
NetHack C sources to tabulate the data fields, and store
them in an intermediate file called util/nethack.tags
(not required for building NetHack if you already have a
generated include/sfproto.h and src/sfdata.c)
util/readtags (also not required for building NetHack
itself) will decipher the nethack.tags file and produce
the functions that can deal with the NetHack struct data
fields.
You can obtain the source for universal-ctags by cloning it
from here:
https://github.com/universal-ctags/ctags.git
The combination universal-ctags + util/readtags has been
tried and tested under both Windows and Linux, so it is
not tied to a particular platform.
Note: util/readtags will work only with universal-ctags
output, so other ctags are unlikely to work as-is.
Universal-ctags can be build from source very easily
under Linux, or under Windows using visual studio.
When dgn_comp.l and lev_comp.l are processed by older versions of
flex, 'gcc -Wunused' complains when compiling dgn_lex.c and lev_lex.c
because flex creates 'static void yyunput()' and nethack doesn't use
it. Newer versions honor macro YY_NO_UNPUT to hide the offending
code, but that doesn't help with older versions (like the one
masquerading as 'lex' on OSX). Adding a dummy usage would probably
cause problems with other lexers, so change it from static to
'void yyunput()' as a 'sed' fixup in util/Makefile after flex has
finished. That will be a no-op when yyunput doesn't exist or isn't
static.
In addition to the sys/unix/Makefile.utl change, this checks in new
sys/share/{dgn,lev}_lex.c with the fixup in place.
[Subject should mention Unix, but would exceed 50 characters.]
Explicit build rules ignore $(CPPFLAGS), but the implicit C rule
(at least in GNU make) specifies it. If user has a value for this
in the environment, that value would apply to building some source
files but not others. This patch gives it an explicit empty value,
so building via implicit rule should expand it to nothing and match
the fact that it's omitted from explicit rules.
There was one C++ file which relied on the implicit C++ rule. I've
added it to the files processed by 'make depend' and re-run that.
It now will get built via an explicit rule.
Also, a small amount of reformatting for HACKCSRC.
For make install or update, dlb.o was being recompiled unnecessarily
when building util/dlb because the dependency in Makefile.utl listed
hack.h instead of config.h for it. Then attempting to run nethack
under debugger control could cause debugger complaints about dlb.o
being newer than nethack.
Updated for unix and vms.
I just tried to build with MONITOR_HEAP defined in unixconf.h plus
WANT_WIN_X11=1 for make. tile2x11 wouldn't link. It doesn't use
alloc() and free(), but it does link with drawing.o, and drawing.o
has calls to free(), so MONITOR_HEAP makes it need nhfree() from
alloc.o.
All the miscellaneous tile utilities seem to link with drawing.o, so
they all need alloc.o too, and that drags in util/panic.o as well.
I've only changed it for Unix where I can actually test the change
but other platforms probably should do this too. Or we need to redo
drawing.c so that the small subset of stuff utilities want is
separate from the code the core uses for that same stuff.
Change the 'make' rules for *_lex.c, *_yacc.c, and *_comp.h to put
the end files names into whatever #line directives that refer to
the generated names (lex.yy.c, y.tab.c, y.tab.h). This should not
produce any change in behavior during compilation except to provide
more accurate specifications of where any warnings or errors occur.
Add a 'make dist' target that copies generated scanner and parser
files to sys/share. (As mentioned in the previous patch, I haven't
committed any of those since I have different versions of flex and
also of bison.)
Update the unix Makefiles and the older OSX hints files to handle the
pile marker tile overlay. I didn't touch hints/macosx10.10 and .11
since I think there's still a merge for them pending.
A couple of formatting tweaks for bemain.c are included, for no
compelling reason. What are the odds that anyone will every build
that again?
Confusing build failure, explained by a typo in sys/unix/Makefile.utl.
dgn_lex.o didn't get rebuilt after modifying unixconf.h to take out
the #define MONITOR_HEAP I had in place, resulting in link failure for
dgn_comp because the old object file was referencing 'nhalloc' rather
than 'alloc'. dgn_lex.o accidentally didn't care about modifications
to config.h and the other headers that pulls in, such as unixconf.h.
This typo was already present when the last cvs repository was
initialized nearly 14 years ago.
* Add missing entry for include/tile.h to (top)/Files; also
add new entry for generated file util/tiletxt.c (Unix only);
* Add several missing entries for tile utility programs that
can be built by sys/unix/Makefile.utl to util/.gitignore;
* Update sys/unix/Makefile.utl to build 'tilemap' differently so
that it won't leave behind an unwanted subdirectory tree under OSX:
util/tilemap.dSYM/
util/tilemap.dSYM/Contents/
util/tilemap.dSYM/Contents/Info.plist
util/tilemap.dSYM/Contents/Resources/
util/tilemap.dSYM/Contents/Resources/DWARF/
util/tilemap.dSYM/Contents/Resources/DWARF/tilemap
It now generates util/tiletxt.c on the fly, to be compiled into
tiletxt.o, so that tilemap.c can be compiled in the ordinary
manner and tilemap.o can be kept around for dependency checking.
(Creating real source file win/share/tiletxt.c would be a little
bit cleaner, but it's effectively two lines long so seems silly
to be in the source distribution.) I looked to see whether I
could find a linker or compiler option to suppress that stuff but
failed. I'm sure something of the sort must exist but didn't
pursue it. Someday I might actually learn about how OSX works....
Pat noted that I neglected to drop the SCCS lines on the files I've been
committing, so clean up those and any others I could find where the SCCS
line date is out of date.
If SHELLDIR is null, don't install nethack.sh. Also a tid in Porting
and add NHSROOT to the Makefiles which gives a path to the top of the
tree (so e.g. you can always find makedefs from a rule in a hints file).
use makedefs --grep in Makefile.doc
call make clean in doc from make clean in top
add commented out rule to produce mdgrep.h from mdgrep.pl
macosx1.5: don't chown/chgrp for single-user install
unixmain.c: work around C90 warning for Mac-specific code, fix last fix
makedefs.c: temporarily disallow blank after control introducer until docs
catch up
mdgrep.pl: add ALLDOCS, clean up generated file's header
build system.
Anyone who wants to do a build from sys/unix and doesn't want to figure this
out just needs to do:
sh setup.sh hints/unix
instead of:
sh setup.sh
and then continue on as usual.
New files:
sys/unix/NewInstall.unx - the new directions
sys/unix/hints/* - the hints files. There will be more later.
sys/unix/mkmkfile.sh - helper for setup.sh
Summary of changes:
see NewInstall.unx for info on the new build system
introduction of various preprocessor symbols to turn options off that
are defaulted on historically
comment out nethackrc (and similar) entries that still use the old symbol
syntax.
commenting out of Makefile.* lines that now come from hints/unix
GAMEDIR is replaced with HACKDIR so the Makefiles and the C source agree.
Note that I have NOT changed the docs and/or Makefiles for be, msdos, os2,
vms, or winnt. If port maintainers don't then I will, but I can't test
those ports.
nethack.sh now handles the font path automatically
<Someone> noticed that if one builds something in util and the required .o
files aren't already built in src, the .o gets placed in the wrong place.
Added the missing '-o $@' to the compilation command.
- Pat noticed that makedefs -z makes both vis_tab.[ch], but they could be
built by two makes via make -j, causing corruption
- make -j at top level failed for similar reasons, added several
dependencies to ensure a valid ordering
- these changes will cause extra things to be built if you "make"
individual targets at the top level, but have little effect it you're a
real power user and "make" the actual target in the right directory
