[NTLUG:Discuss] cross-compile to vxworks (m68k) from linux

[Seth Daniel]

I'm beginning to suspect that my target is wrong.  I have a few
pre-compiled binaries that work fine under vxworks, but if I 
run a ``m68k-elf-nm'' on one of these binaries it complains
that it doesn't recognize the format.  I wonder if there are more
m68k targets for gcc than m68k-coff and m68k-elf??
