Just to point out this works fine if you tell make to ignore errors during builds using "-include":

Not saying this is a perfect solution but it does work.

If a makefile "include"s another makefile that doesn't exist and which make doesn't know how to create, make fails. This is normally correct.

However, say there are two "include"d files, both of which are generated. Say make knows how to build the first one, and the contents of the first one will include instructions on how to build the second one.

In this case, make still fails although it could succeed, by building the first file, then re-execing itself, whereupon it would know how to build the second one.

Repeat by:

$ cat Makefile
there: hi ; @echo there
a.mk: ; echo 'b.mk: ; echo "hi: ; @echo hi" > $$@' > $@
include a.mk
include b.mk

$ make
Makefile:3: a.mk: No such file or directory
Makefile:4: b.mk: No such file or directory
make: *** No rule to make target `b.mk'. Stop.
