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

[Corley, Mark]

Hi Seth,

I personally don't have any experience trying to compile to a VxWorks target
under Linux; however, I have run across this web page that supposedly has
some details about doing what you are contemplating:

	http://kofa.as.arizona.edu/vxworks/

The person who did this work seems to have built a cross-compiler version of
gcc (and it supporting GNU utilities) using a "-target" option to configure
of the following:

	i386-wrs-vxworks

which builds a cross version of gcc for an Intel x86 processor running
VxWorks. They also refer to building a cross version of gcc to m68k
processor running VxWorks using a "--target" option to configure of the
following:

	m68k-wrs-vxworks

The page is pretty detailed and definitely worth checking out.

Hope that this helps!!

later,
mark
