Well, of course not, it's a source file. This is a new MQX project - all compiles fine, Eclipse/CW10 workspace is separate from MQX-3.6.2 installation directory. Looking at the makefile doesn't help - moo.elf depends on intflash.lcf and the rest of my source files. I'm feeling pretty stupid right about now - I never had this kind of trouble with hand-built makefiles, but that was a few years ago. Regards, Donald.
