However, I did learn the following vendors support PowerPC and VxWorks: Green Hills OC Systems Rational (Solaris host only, and pricy!) Aonix is also supporting the PowerPC, but doesn't have details on their web page -- they say call them if you are interested. For more information and contacts, go to http://www.adahome.com/Resources/Compilers/Vendors.html and take a look.
