I found Erich Styger's article on invoking command line builds for KDS, which was very helpful. Trouble is, I'm using MQX-Lite, which unfortunately requires Processor Novice (oops, Processor Expert), and that seems to be throwing a wrench into it. I'm getting an error that says:
Managed Build system manifest file error: Unable to resolve the superClass identifier com.processorexpert.cdt.gcc.toolchain.builder in the bulder com.processorexpert.cdt.gcc.toolchain.debug.builder.
I've turned off code generation in Processor Expert, but it didn't make a difference. I've tried running the eclipsec command line from both the workspace and the eclipse directory, but it worked the same. Is it just a path issue?
