With sufficient thrust, pigs fly just fine. However, this is
not necessarily a good idea. It is hard to be sure where they
are going to land, and it could be dangerous sitting under them
as they fly overhead. -- RFC 1925

Subject: cross compiler error

Hi, there,

I will install the EPICS Server under vxWorks version 5.4.2 (for
Motorola MVME 5100). I downloaded the cross-compiler file,
cross-gcc-2.9.6.tar.gz, for linux from http://ics-web.sns.ornl.gov/dht/.
Untar it and configured WIND_BASE in mkCrossGCC file. When I run
./mkCrossGCC CPU=ppc, I got the following error message. Could someone
help me?
