Re: Executing a shell script in a Makefile

[G2345C]

Sorry for the confusion. My typo problem

the makefile is like this:
all :
      $(SHELL) ./copyfile.sh
      cd $(OBJ_DIR) && mv foo.o newfoo.o

foo.o is a very large file that copy to $(OBJ_DIR) by
the 'copyfile.sh' script.
While the copy is in progress the 'mv' is executing
cause it to fail becase foo.c is not yet copy to the
$(OBJ_DIR)

Thanks
