Hello,
Why MAKEFLAGS is set to `w' in sub directory?
When I invoke make command in sub directory. Then MAKEFLAGS is not set.
$ cd sub
$ make
!!! Debug: MAKEFLAGS =
However, I invoke make command in parent directory, then MAKEFLAGS is set
to `w' in sub directory.
$ cd ..
$ make
!!! Debug: MAKEFLAGS =
make -C sub
make[1]: Entering directory `/home/asou/tmp/sample/sub'
!!! Debug: MAKEFLAGS = w
make[1]: Leaving directory `/home/asou/tmp/sample/sub'
My Makefiles are below.
$ cat Makefile
all:
@echo "!!! Debug: MAKEFLAGS = $(MAKEFLAGS)"
make -C sub
$ cat sub/Makefile
all:
@echo "!!! Debug: MAKEFLAGS = $(MAKEFLAGS)"
I am using Centos 7.2 on VMware FUSION.

I am using GNU Make 3.82.
$ which make
/usr/bin/make
asou@vmcentos:~/tmp/sample 17:52:11
