I am using the ARM 2011.03 GNU EABI cross-compiler from CodeSourcery (which apparently changed its name to Mentor Graphics). The Lite versions of the compilers are a bit harder to find, but you can download the latest ones over here: http://www.mentor.com/embedded-softw.../lite-edition/ You have to register first, but you can get the compilers directly from: https://sourcery.mentor.com/sgpp/lit...al/release2029 I use these compilers directly on my linux OS so not in a scratchbox environment. See if this somehow already helps with the missing headers files. Davy
