Details:
bash-3.00$ cat makefile
-include abc.def
-include abc.dep
%.do :
echo "$@: $^"
/bin/rm -f $*.dep $*.def
%.dep : %.def
echo "$*.do : $(DEF)" > $@
%.def :
echo "DEF := $*" > $@
makefile : ;
abc : ;
===========================================
Here's the o/p when we run with make 3.80
bash-3.00$ /sw/packages/make/3.80/bin/make abc.do
echo "DEF := abc" > abc.def
echo "abc.do : " > abc.dep
echo "abc.do: "
abc.do:
/bin/rm -f abc.dep abc.def
===========================================
When we run with 3.81
bash-3.00$ /sw/packages/make/3.81/bin/make abc.do
echo "DEF := abc" > abc.def
echo "abc.do : " > abc.dep
echo "DEF := abc" > abc.def
echo "DEF := abc" > abc.def
echo "DEF := abc" > abc.def
....
....
....
===========================================
AFAIK the issue here is make 3.81 is considering the .def file as
intermediate file and deleting it after producing the .dep file so every time
when it is re-reading the include statements it is not able to find the .def
file and it is going into infinite loop.
when we add:
.SECONDARY : abc.def
or
.SECONDARY:
then make-3.81 does not delete abc.def (as part of cleaning up the
intermediate files).
One more thing of interest here is if we change the order of includes to
-include abc.dep
-include abc.def
Then make 3.81 works fine !!.
