_______________________________________________________
Details:
Two makefiles are attached.
Without -e, $(origin FOO) remembers
that FOO came from the command line.
masahiro@grover:~$ make FOO=1
the origin of FOO: command line
FOO: 1
MAKEOVERRIDES: FOO=1
make -f Makefile.sub
make[1]: Entering directory '/home/masahiro'
the origin of FOO: command line
FOO: 1
MAKEOVERRIDES: FOO=1
make[1]: Leaving directory '/home/masahiro'
With -e, $(origin FOO) in the sub-make
shows 'environment' while it was given
from the command line.
Interestingly, FOO=1 was removed from $(MAKEOVERRIDES)
masahiro@grover:~$ make -e FOO=1
the origin of FOO: command line
FOO: 1
MAKEOVERRIDES: FOO=1
make -f Makefile.sub
make[1]: Entering directory '/home/masahiro'
the origin of FOO: environment
FOO: 1
MAKEOVERRIDES:
make[1]: Leaving directory '/home/masahiro'
