Some support of new code #defines to faciliate cross-compiling:
OPTIONS_AT_RUNTIME If this is defined, code to support obtaining
the compile time options and features is
included. If you define this, you'll also have
to compile sys/mdlib.c and link the resulting
object file into your game binary/executable.
CROSSCOMPILE Flags that this is a cross-compiled NetHack build,
where there are two stages:
1. makedefs and some other utilities are compiled
on the host platform and executed there to generate
some output files and header files needed by the
game.
2. the NetHack game files are compiled by a
cross-compiler to generate binary/executables for
a different platform than the one the build is
being run on. The executables produced for the
target platform may not be able to execute on the
build platform, except perhaps via a software
emulator.
The 2-stage process (1. host, 2.target) can be done
on the same platform to test the cross-compile
process. In that case, the host and target platforms
would be the same.
CROSSCOMPILE_HOST Separates/identifies code paths that should only be
be included in the compile on the host side, for
utilities that will be run on the host as part of
stage 1 to produce output files needed to build the
game. Examples are the code for makedefs, tile
conversion utilities, uudecode, dlb, etc.
CROSSCOMPILE_TARGET Separates/identifies code paths that should be
included on the build for the target platform
during stage 2, the cross-compiler stage. That
includes most of the pieces of the game itself
but the code is only flagged as such if it must
not execute on the host.
If you don't define any of those, things should build as before.
One follow-on change that is likely required is setting the new dependency
makedefs has on src/mdlib.c in Makefiles etc.
More information about the changes:
makedefs
- splinter off some of makedefs functionality into a separate file
called src/mdlib.c.
- src/mdlib.c, while included during the compile of makedefs.c
for producing the makedefs utility, can also be compiled
as a stand-alone object file for inclusion in the link step
of your NetHack game build. The src/mdlib.c code can then
deliver the same functionality that it provided to makedefs
right to your NetHack game code at run-time.
For example, do_runtime_info() will provide the caller with
the features and options that were built into the game.
Previously, that information was produced at build time on the
host and stored in a dat file. Under a cross-compile situation,
those values are highly suspect and might not even reflect the
correct options and setting for the cross-compiled target
platform's binary/executable. The compile of those values and
the functionality to obtain them needs to move to the target
cross-compiler stage of the build (stage 2).
- date information on the target-side binary is produced from
the cross-compiler preprocessor pre-defined macros __DATE__
and __TIME__, as they reflect the actual compile time of the
cross-compiled target and not host-side execution of a utility
to produce them. The cross-compiler itself, through those
pre-defined preprocessor macros, provides them to the target
platform binary/executable. They reflect the actual build
time of the target binary/executable (not values produced
at the time the makefiles utility was built and the
appropriate option selected to store them in a text file.)
- most Makefiles should not require adding the new file
src/mdlib.c because util/makedefs.c has a preprocessor
include "../src/mdlib.c" to draw in its contents. As previously
stated though, the Makefile dependency may be required:
makedefs.o: ../util/makedefs.c ../src/mdlib.c
^^^^^^^^^^^^^^^
Bug report #H7156 listed three items, all relating to perm_invent:
1) it shouldn't persist across save/restore since restore might be
on a system which doesn't have enough room to display it (report
actually complained that config file setting was ignored when
restoring old games, which is an expected side-effect for options
that persist across save/restore);
2) permanent inventory wasn't updated when using scroll of charging;
3) attempts to update permanent inventory during restore could lead
to crash if it tries to access shop cost for unpaid items.
Items (2) and (3) have already been fixed. This fixes (1).
Replace 'flags.perm_invent' with a dummy flag, preserving save files
while removing it from flags. Add 'iflags.perm_invent' to hold the
value of the perm_invent option.
The win32 files that are updated here haven't been tested. Whichever
branch contains the curses interface needs to be updated; ditto for
any other pending/potential interfaces which support perm_invent.
Black is a better choice given that the map background
will always be black. This also creates a better polished
experience when all window backgrounds are set to black.
I'll push a formatting guide at some point. There may still be
outstanding changes, but please feel free to resolve those as you arrive
a them.
To the best of my knowledge, there is no changes to the actual code
content, but the formatter does have the occasional bug. If you run into
an issue, please fix it!
There is a lot of code affected by this, and Pat Rankin correctly
observes that it would be better to store roguelike as a level flag
rather than just using Is_rogue_level. A note for the future.
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.
Tested on the unix port; I've updated as many other ports as I can figure
out but they're not tested. See window.doc for info on the changed banner
lines. Also adds the ability to override the generic "Unix" port - used now to get
"MacOSX" into the version line instead of "Unix" (so we don't scare people who don't
know what's going on).

trunk patch:
- menu: display custom tiles if map is not ASCII
- menu: display '-'/'+'/'#' in place of a tile if map is ASCII
- fix isdigit() crash on AltGr-4 with mingw
It looks kinda weird with huge tiles (e.g. absurd96) but that could
be just me. Comments/suggestions are welcome.
-<Someone>
trunk and branch:
Do not limit role selection list by race/gender/alignment. The default.nh
selection will still be honored but the list itself will include every
possible role.
Some interface tweaks for main trunk:
- improved calculation of the size of the menu window
- made auto-arrange windows on/off option (it was reset automatically
which was unintuitive and in some cases annoying, IMO)
- set correct checkmark on "Lock Windows" menu item on startup
- redraw message window on resizing (it does not update properly otherwise)
- fixed copy/paste error in read registry settings function
The number_pad option can now optionally hold a value
{0,1, 2 } for {off, on, DOS-mode} but plain number_pad and
!number_pad in config files still work as before.
When number_pad:2 is set, iflags.num_pad_mode is set to 1
which triggers the following behaviour:

What's in it:
some MessageBox tidbits:
- Let all MessageBoxes display an icon
- Introduced NHMessageBox to have messageboxes display a consistent title
- Change icon in mswin_display_file from MB_ICONERROR to MB_ICONEXCLAMATION
for non-fatal error
And to solve #U355: NetHackW won't run on Win2K OS:
- Avoid a crash when closing the main window while the splash screen is
displayed.
- Make sure NetHack starts normal when closed minimized
- Center the splash screen on the screen, not on the parent window
(which may be off-screen)
What's new in it:
- Show copyright banner in textbox in splash screen instead of over the picture
- Show news in splash screen only if iflags.news (solves W341-6)
- show complete version information in splash screen when it is used as about box)
[Also reverse the numkey patch in main trunk]
- My "various Windows refinements" patch from yesterday went into 3.4.x correctly
- My "NumberPad" patch went into 3.4.x, but should be backed out
- My "various Windows refinements" patch from last week was for 3.5.0, but is incomplete; you can safely ignore that.
- I'll make a new "various Windows refinements" patch for 3.5.0 tonight.
mapping the 5 and 0 to '5' and '0' respectively
when NumLock is off, to make entering numbers easier. The core will map '5' and
'0' to 'g' and 'i' respectively. This solves W341-5.
Note: I changed nhdefkey.c and mhmain.c, so both the tty and the windows
interface will show new behaviour. I deliberately did not change nh340key.dll.
Note: Maybe the same change should be made to the MSDOS port.
Note: The behaviour of getobj is a little bit strange: It doesn't use
yn_question's facility for returning a number, but handles that itself. The
net effect of this is that if you type d55$ (to drop 55 zorkmids,) only the
first '5' is shown
(2 troublesome bands removed
and will follow later)
Here's the new patch with the Windows improvements; this should apply to the
3.4.2 tree. Note the changed filename in the diff lines.

What's new in it:
- Show copyright banner in textbox in splash screen instead of over the picture
- Show news in splash screen only if iflags.news (solves W341-6)
- show complete version information in splash screen when it is used as about
box
-better handling of "more" prompt for messages that would have scrolled off the window
-support perm_invent
-menu option to add/remove windows captions
- Show splash on "Help - About" with all version information
- Show splash with news on startup (if show_splash is on of course).
I made another small patch to the splash screen. Because the greenish background colour always seemed a little odd to me, I decided
to make it transparent. Doing that, I found the following:
- The splash picture was a 24-bit bitmap, although it had less than 256 colours. That makes the size of the final executable about
200K larger than necessary. I changed it to a 256-colour bitmap. I also changed the background colour to the default tile background
colour, for consistency. The new bitmap is attached here. My excuses if the large file means a problem to anyone.
- In Microsoft's documentation (see http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gdi/bitmaps_2y9g.asp) is is
stated that on Windows 95/98 "TransparentBlt contains a memory leak that can exhaust system resources." It is recommended to use
different code to draw transparent bitmaps, to be precise: the alternative code that is already in nhapply_image_transparent(). I'm
almost convinced that this is the cause for Betabug B08008 reported bij <Someone>. Can anyone confirm he is using 95/98? I decided
for the easy way out and removed the code that uses TransparentBlt completely. I see not much reason to use it if it is a) buggy and
b) we have an alternative that works perfectly. This is attached as trans.patch.
- The rest of the patch only changes the BitBlt() in mhsplash.c to a nhapply_image_transparent().
This patch is an improvement for menu/text dialogs.
This is a code carried over from Windows CE port. It changes
text and menu windows from "system popup" to plain "child"
windows of the main nethack window. Nethack main window can
now be resized/moved/minimized when menu/text window is up.
Menu/text windows will always stay inside the main window and
move along with it.

At end of game is probably the only place, since then more than one
question is asked in the same turn. Anyhow, here's the patch, in
mswproc.c [...]
- No checkboxes in menu if menu is PICK_NONE. mhmenu.c
- About box changed to splash screen. This last thing is open
for discussion, as the splash screen currently does not give
exactly the ame information as the about box (or the v command).
Maybe the splash should be enhanced? Anyway, it looks better than
the About-box. I didn't remove the About-box code and resource yet
until this discussion is had. mhmain.c
