Description
As the title says, if objdir and targetdir point to the same directory, then we'll get some errors:
Basic.C.make:72: warning: overriding commands for target `.'
Basic.C.make:64: warning: ignoring old commands for target `.'
This makes sense if we look at the makefile:
$(TARGETDIR):
@echo Creating $(TARGETDIR)
ifeq (posix,$(SHELLTYPE))
$(SILENT) mkdir -p $(TARGETDIR)
else
$(SILENT) mkdir $(subst /,\\,$(TARGETDIR))
endif
...
$(OBJDIR):
@echo Creating $(OBJDIR)
ifeq (posix,$(SHELLTYPE))
$(SILENT) mkdir -p $(OBJDIR)
else
$(SILENT) mkdir $(subst /,\\,$(OBJDIR))
endif
If the directories are the same, then only one of these targets needs to be generated.
