Disclaimer: This is a minimal recipe, just to get someone else
started if they have a desire to get a full cross-compile of
NetHack-3.7 going for the Amiga. Some NetHack code bitrot was
corrected, and it does seem able to compile the game itself
to a point. See caveats below.
- If you want to obtain the cross-compiler and tools/libs for Amiga
https://github.com/bebbo/amiga-gcc
To our knowledge, a pre-built copy isn't available, so you have to
obtain the source via git and build it on your system.
The build prerequisite packages for Ubuntu are easily obtained:
sudo apt install make wget git gcc g++ lhasa libgmp-dev \
libmpfr-dev libmpc-dev flex bison gettext texinfo ncurses-dev \
autoconf rsync
The build prerequisite packages for macOS are apparently easily
obtained via homebrew, but that was not tested:
brew install bash wget make lhasa gmp mpfr libmpc flex gettext \
texinfo gcc make autoconf
After installing the prerequite packages and the cross-compiler
it was a straightforward build:
git clone https://github.com/bebbo/amiga-gcc.git
cd amiga-gcc
make update
[Note that you may have to take ownership of the files in the
bebbo repo via chown before succesfully carrying out the next
steps]
make clean
make clean-prefix
date; make all -j3 >&b.log; date
The compiler pieces are installed in /opt/amiga by default which
was satisfactory for our initial attempt, but if you want you can
alter the prefix before you build if you want. That is all
spelled out on the page at: https://github.com/bebbo/amiga-gcc
The Amiga cross-compile can then be carried out by specifying
CROSS_TO_AMIGA=1 on the make command line.
For example:
make CROSS_TO_AMIGA=1 all
make CROSS_TO_AMIGA=1 package
You can explicitly include tty and curses support if desired, otherwise
you'll end up with a tty-only cross-compile build. The SDL1 pdcurses
support has not been tested.
make WANT_WIN_TTY=1 WANT_WIN_CURSES=1 CROSS_TO_AMIGA=1 all
Also note that building the amiga targets using the make command
above, does not preclude you from building local linux or macOS
targets as well. Just drop the CROSS_TO_AMIGA=1 from the make
command line.
The cross-compiler hints additions are enclosed inside ifdef sections
and won't interfere with the non-cross-compile build in that case.
CAVEATS: The original NetHack Amiga build steps included the source for
some utilities that were built and executed on the amiga: txt2iff and
xpm2iff as part of the NetHack build procedure on amiga. Those did not
compile out-of-the-box on the linux host. They will either have to be:
- ported to build and run on the linux or macOS cross-compile host
or
- their functionality will have to be rolled into amiga NetHack
itself and executed on the target Amiga the first time the game
is run, perhaps.
Good luck amiga aficionados, perhaps you'll be able to take this
initial effort forward and get NetHack-3.7 available on the amiga or
amiga-emulator. Let us know if you do, and we can roll changes in
if you provide them.
A check into github issue 364 confirmed that
ba6edbe5dc
had incorrectly updated the bwrite sizeof entry for sysflags.
The SYSFLAGS and MFLOPPY code is all in the outdated part of the tree, so just
remove it rather than re-correct it.

Rand() was typically defined to random() or to rand().
gcc seems to provide a random() to link to on linux
when sys/share/random.c is linked in, but other platforms
such as Windows got an undefined refence to random()
when RANDOM wasn't defined.
The only direct use seems to be in get_rnd_txt() these
days, in rumors.c
Under the USE_ISAAC64 config, neither srandom()
nor srand() are being invoked to seed those routines,
and it really should be using isaac64 when USE_ISAAC64
is defined anyway.
I did my best to exempt some of the bigger aligned blocks from the reformatting
using the /* clang-format off */ and /* clang-format on */ tags. Probably some
that shouldn't have been formatted were anyway; if you encounter them, please
fix.
The clang-format tags were left in on the basis that it's much easier to prune
those out later than to put them back in, and it means that, modulo my custom
version of clang-format, I should be able to run clang-format on the source tree
again without changing anything, now that Pat has fixed the VA_DECL issues.

../src/cmd.c:1801: warning: case value out of range
The NOCWD_ASSUMPTIONS conditional code allows readonly
parts of NetHack to be separated from areas that require write-access.
This allows the recent panic log needed a prefix.
