Hi Matt,

Well, you could have the makefile increment the buildnumber:

include buildnum
NEW_BUILDNUMBER = $(shell echo $$(( $(BUILDNUMBER) + 1 )))

This takes advantage of the shell's capability to evaluate expressions
using the

$(( expression ))

syntax, The double $ gets converted to a single $ by the time the
shell is invoked.

Add the following two lines to your linker recipie after a successful link:

    @echo "# Automatically generated file - do not edit" > buildnum
    @echo "BUILDNUMBER=$(NEW_BUILDNUMBER)" >> buildnum
