Oops, it's wrong. Now I have "-DWORLD32" in LIB32MAKE and
the following lines in lib/ncurses/Makefile
.if !defined(WORLD32)
INCS= ${HEADERS} ${SRCHDRS}
INCSLINKS= curses.h ${INCLUDEDIR}/ncurses.h
.endif
While make universe is still running, but I have amd64, i386, pc98
work and on my -current i386 box. The resulting world works well
(tested by mutt).
I'm not sure if this is the best way to handle this. I noticed that
Dragonfly has something like
# include files are not installed when building bootstrap programs
.if !defined(BOOTSTRAPPING)
realinstall: installincludes
.ORDER: beforeinstall installincludes
.endif
in bsd.incs.mk.
For ncurses, since the include path for 32-bit includes are specified
in LIB32POSTFLAGS, which is part of ${CC}. When building ncurses +
ncursesw, I need different versions of ncurses.h (for runtime, it is not
the case).The only way to get them build in lib32 is NOT to install ncurses.h
in lib32/usr/include.
Any comments or suggestions are welcome :)
