>From experience with v3.80 of GnuMake, I came to the conclusion that
the files listed behind an include directive are processed in opposite order
(last one first). Although I haven't seen this fact documented anywhere.
This could cause your problem, since order of evaluation is important
when using ':=' variable assignments.
Thus you could change your first line into:
-include include2 include1
That should do the trick..
Talking about the include directive, Is the following "creative" use of
include
common practice?
-include $(if $(MAKDIR), $(MAKDIR)/makerules.mak, $(error MAKDIR is not
defined))
where MAKDIR is an environment variable that shouls be supplied by the shell
