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

NetHack 3.7.0 work-in-progress -- General information
NetHack 3.7 is an enhancement to the dungeon exploration game NetHack,
which is a distant descendent of Rogue and Hack, and a direct descendent of
NetHack 3.6.
NetHack 3.7.0 work-in-progress is not an official release of NetHack. It
currently contains a number of enhancements to NetHack 3.6.3. The file
doc/fixes37.0 in the source distribution has a full list of them.
The text in there was written for the development team's own use and is
provided "as is", so please do not ask us to further explain the entries
in that file. Some entries might be considered "spoilers", particularly in
the "new features" section.
Below you will find some other general notes that were not considered
spoilers:
* automatic annotation "gateway to Moloch's Sanctum" for vibrating square level
once that square's location becomes known (found or magic mapped);
goes away once sanctum temple is found (entered or high altar mapped)
* savefile: add support to deconstruct internal data structures down into their
individual fields and save those fields instead of the entire struct
* savefile: use little-endian format for fields where that makes a difference
- - - - - - - - - - -
Please read items (1), (2) and (3) BEFORE doing anything with your new code.
1. Unpack the code in a dedicated new directory. We will refer to that
directory as the 'Top' directory. It makes no difference what you
call it.
2. Having unpacked, you should have a file called 'Files' in your Top
directory.
This file contains the list of all the files you now SHOULD
have in each directory. Please check the files in each directory
against this list to make sure that you have a complete set.
This file also contains a list of what files are created during
the build process.
The names of the directories listed should not be changed unless you
are ready to go through the makefiles and the makedefs program and change
all the directory references in them.
3. Before you do anything else, please read carefully the file called
"license" in the 'dat' subdirectory. It is expected that you comply
with the terms of that license, and we are very serious about it.
4. If everything is in order, you can now turn to trying to get the program
to compile and run on your particular system. It is worth mentioning
that the default configuration is SysV/Sun/Solaris2.x (simply because
the code was housed on such a system).
The files sys/*/Install.* were written to guide you in configuring the
program for your operating system. The files win/*/Install.* are
available, where necessary, to help you in configuring the program
for particular windowing environments. Reading them, and the man pages,
should answer most of your questions.
At the time of this release, NetHack 3.6 has been tested to run/compile
on:
Intel Pentium or better (or clone) running Linux, BSDI, or
Windows (7 through 10)
Intel 80386 or greater (or clone) boxes running Linux, or BSDI

Instructions have been provided by way of community contribution on:
msdos protected mode using djgpp

If you have problems building the game, or you find bugs in it, we recommend
filing a bug report from our "Contact Us" web page at:
https://www.nethack.org/common/contact.html
Please include the version information from #version or the command line
option --version in the appropriate field.
A public repository of the latest NetHack code that we've made
available can be obtained via git here:
https://github.com/NetHack/NetHack
or
https://sourceforge.net/p/nethack/NetHack/
When sending correspondence, please observe the following:
o Please be sure to include your machine type, OS, and patchlevel.
o Please avoid sending us binary files (e.g. save files or bones files).
If you have found a bug and think that your save file would aid in solving
the problem, send us a description in words of the problem, your machine
type, your operating system, and the version of NetHack. Tell us that you
have a save file, but do not actually send it.
You may then be contacted by a member of the development team with the
address of a specific person to send the save file to.
o Though we make an effort to reply to each bug report, it may take some
time before you receive feedback. This is especially true during the
period immediately after a new release, when we get the most bug reports.
o We don't give hints for playing the game.
o Don't bother to ask when the next version will be out or you can expect
to receive a stock answer.
If you want to submit a patch for the NetHack source code via email directly,
you can direct it to this address:
nethack-bugs (at) nethack.org
If a feature is not accepted you are free, of course, to post the patches
to the net yourself and let the marketplace decide their worth.
All of this amounts to the following: If you decide to apply a free-lanced
patch to your 3.6 code, you are welcome to do so, of course, but we won't
be able to provide support or receive bug reports for it.
In our own patches, we will assume that your code is synchronized with ours.
-- Good luck, and happy Hacking --
