RE: Problem with $* and $$*

[PATTON, BILLY \(SBCSI\)]

As one who has recently gone through this These are the changes I would
suggest
$< to $$<

get rid of the shell,   It already is in a shell

I would suggest breaking it into small pieces for better readability


CPP = $(CXX) -MM $(FINAL_$(1)_CPPFLAGS) $(CXXINCLDIRS) $$<

$(OBJ_DIR)$(1)_%$(DBG_SUFFIX)$(DEP_EXT) : $(2)/%$(SRC_EXT)
    $(VERBOSE_ECHO) $(SHELL) -ec '$(CPP) | sed '\''s/\($$*\)\.o[
:]*/$(shell echo $(OBJ_DIR)$(1)_ | sed 's/\//\\\//g')\1$(DBG_SUFFIX).o
$(subst /,\/,$$@) : /g'\'' > $$@'
