Re: Executing a shell script in a Makefile

[G2345C]

because the next statement get executed and it failed
because foo.o is not yet get copy.

Now if I modified the makefile to this:
all :
       $(SHELL) ./copyfile.sh
then run it.

wait for about 1 minute....
then modify the makefile to this:
all :
       cd $(OBJ_DIR) && mv foo.o newfoo

then run again it work great

Thanks for your help
