Cross-compiling NetHack 3.7 Last edit: May 31, 2020
The NetHack 3.7 build process differs from the build process of previous
versions in some important ways that make it possible to use a cross-compiler

for use in linking other HOST utilities if the HOST-native obj files
produced from them are still around.
NOTE: Other source files (src/drawing.c) that need to
be compiled for native HOST utilities, also need to be compiled again
later as TARGET obj files for linking into the TARGET executable. It is
important to keep the compiled HOST-side obj files produced by the HOST
native compiler, and the TARGET-side obj files produced by the
cross-compiler separate and distinct from one another. That can be done
either by naming the differing object files a little differently
(perhaps with a suffix), or by placing the HOST-side obj files and the
TARGET-side obj files into different folders during the build process.
Whatever works best for your cross-compile.
NOTE: There are some source files that need to be compiled for linking
into utilities that are needed on the HOST side, but that are also
needed again later as TARGET obj files for linking into the TARGET
executable, and therefore must be compiled twice.
They include: src/drawing.c, src/objects.c, src/monst.c,
src/alloc.c, util/panic.c. It is important to keep the compiled
HOST-side obj files produced by the HOST native compiler distinct from
the TARGET-side obj files produced by the cross-compiler. That can be
accomplished either by naming the generated object files a little
differently (perhaps with a suffix) between the HOST-side and the
TARGET-side, or by placing the HOST-side obj files and the TARGET-side
obj files into distinct, different directories during the build process.
Use whatever method works best for your cross-compile effort and tools.
