When using autodependency as described in info the behavior of make
changed between 3.79.1 and 3.81 generating unexpected confusion -
makefile exits without error message but does not finish the target(s):
[o:[EMAIL PROTECTED] ~...tmp]$more .deps/test.P
test.o .deps/test.P : test.c xxxx
the xxxx above is bogus file, but it represents valid include file which
was deleted or moved
when makefile contains
include $(dep_files)
the result is as expected (It is PITA, but at least message is clear,
could it be possible to add rule to delete .deps/test.P and remake it ?)
[o:[EMAIL PROTECTED] ~...tmp]$make
make: *** No rule to make target `xxxx', needed by `.deps/test.P'. Stop.
but when makefile contains
-include $(dep_files)
makefile 3.81 simply exits
previous versions of make (in particular 3.79.1 in FC2) reported as
expected:
make: *** No rule to make target `xxxx', needed by `.deps/test.P'. Stop.
make -d shows:
......
Found an implicit rule for `test.o'.
Pruning file `test.c'.
Pruning file `test.c'.
Pruning file `xxxx'.
Finished prerequisites of target file `test.o'.
Giving up on target file `test.o'.
Finished prerequisites of target file `a.out'.
Giving up on target file `a.out'.
Actual working makefile attached
