Hi,

It should be possible to cross-build for vxWorks from Cygwin, I suspect you 
just need to make some configuration file changes.

That name should be CROSS_COMPILER_TARGET_ARCHS, I suspect you just typed it 
wrong in your email though.

I suspect the problem is that the value for CROSS_COMPILER_TARGET_ARCHS that 
you set in CONFIG_SITE gets overridden in the file 
configure/os/CONFIG_SITE.cygwin-x86.Common where it currently gets set to 
empty by default (this is a bug which I will fix).  Try commenting out the 
setting in that file, or moving it there instead, then run 'make' from the top 
directory again.

You might need to change your vxWorks target architecture and use the one 
called vxWorks-ppc604_long instead, since MVME5100 boards have more than 32MB 
of RAM.  You'll know that is the case if you see the error "Relocation value 
does not fit in 24 bits." when the startup script loads the IOC's .munch file.  
There is more information about this issue at
    http://www.aps.anl.gov/epics/base/ppc.php#Relocation

I hope this helps,

- Andrew
