I've tried building a linux-686 to netbsd-mac68k cross compiler
numerous times and am now the closest I have ever been to building a
kernel.  I built it using binutils-2.9.1 and gcc-2.8.1 with
--target=m68k-apple-netbsd, including --with-gnu-as and with-gnu-ld for
gcc.  The snag that I run into is when compiling a kernel it issues the
commands:


 /usr/cross/m68k-apple-netbsd/bin/ld: warning: cannot find entry symbol
start; defaulting to 00002020
"../../../../arch/m68k/fpsp/Makefile.inc", line 22: warning: Couldn't

    This follows by many, many undefined reference errors.  I think this
is close to compiling because it seems to be actually making the netbsd
file (judging by the "-o netbsd" when it calls ld) I just need to find
out what is wrong.  I think it might be the linker, although it could be
something else that screwed up the object files.  If anyone here has any
ideas/suggestions I would like to hear them.  Also, if it's of
significance, I modified the makefile to get rid of the -Werror flag to
gcc, it would not even get this far without removing that.  I get
similar errors when making the shared libm library, that output is
below.

    With errors like these following.  I'm pretty much stumped on this
and need any help I can get.  If anyone reading this has built a cross
compiler from anything to a netbsd system (any arch) it would really
help me if you could try to remember what you did.
