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.
|
||||||
|
|
||||||
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.
