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

[Greg E]

When you cross-compile for another target you need to link with
libraries for that target as well.  I'm not familar with vxworks
off hand, I assume it's an OS for the device?  Device dependend
libraries and drivers you will either need to get from the OEM or
develop yourself.  Check the GNU site for a generic m68k 
cross-compiler.
