Emacs by default uses its own malloc, but the emacs developers have
suggested that I try to build it so that it uses Cygwin's malloc. (See
http://lists.gnu.org/archive/html/emacs-devel/2009-12/threads.html#00369
for the context if you're curious.) When I try to do this, the build
fails as follows:
gcc -o temacs ecrt0.o dispnew.o frame.o scroll.o xdisp.o menu.o
window.o charset.o coding.o category.o ccl.o character.o chartab.o cm.o
term.o terminal.o xfaces.o emacs.o keyboard.o macros.o keymap.o
sysdep.o buffer.o filelock.o insdel.o marker.o minibuf.o fileio.o
dired.o filemode.o cmds.o casetab.o casefiddle.o indent.o search.o
regex.o undo.o alloc.o data.o doc.o editfns.o callint.o eval.o
floatfns.o fns.o font.o print.o lread.o syntax.o unexcw.o bytecode.o
process.o callproc.o region-cache.o sound.o atimer.o doprnt.o strftime.o
intervals.o textprop.o composite.o md5.o sheap.o terminfo.o
lastfile.o vm-limit.o getloadavg.o -lcurses -lg `gcc
-print-libgcc-file-name` -lm -lc `gcc -print-libgcc-file-name`
vm-limit.o:vm-limit.c:(.text+0x17): undefined reference to
`___after_morecore_hook'
vm-limit.o:vm-limit.c:(.text+0x6c): undefined reference to `___morecore'
Is this one of those situations where the libraries are listed in the
wrong order in the gcc command? Or is there something else going on?
I'm attaching my .cygport and .src.patch files in case it's more subtle
and someone else wants to give it a try.
