Hi,
This is a report of a small trouble I encountered when I wrote
`MAKEFLAGS := --warn-undefined-variables' in a makefile.
[/tmp]% uname -srm
Linux 2.4.5-3 i686
[/tmp]% make-3.80rc1/make -v
GNU Make 3.80rc1
...snip...
(description)
The above is the environment of my experiment.
I first encountered the trouble using make-3.79.1, and
found no improvements in make-3.80rc1.
[/tmp]% cat Makefile1
all: $(FOO)
@echo abcde
[/tmp]% make-3.80rc1/make -f Makefile1
abcde
(description)
The above makefile is somewhat erroneous, but `make' does
not print a warning message by default.
[/tmp]% make-3.80rc1/make -f Makefile1 --warn-undefined-variables
Makefile1:1: warning: undefined variable `FOO'
abcde
[/tmp]% env MAKEFLAGS=--warn-undefined-variables \
make-3.80rc1/make -f Makefile1
Makefile1:1: warning: undefined variable `FOO'
abcde
(description)
`make' prints a warning message when I specify
--warn-undefined-variables option in the command line
or in the MAKEFLAGS environment variable. Good.
[/tmp]% cat Makefile2
MAKEFLAGS := --warn-undefined-variables
all: $(FOO)
@echo abcde
[/tmp]% make-3.80rc1/make -f Makefile2
abcde
(description)
`make' does not print a warning message when I specify
--warn-undefined-variables option via the MAKEFLAGS
variable in the makefile. Hmmm....
I can vaguely guess why `make' shows this behavior, so I do not call
it a definite bug. However, I will be happy if `make -f Makefile2'
prints a warning message.
Best regards,
