Thanks for your reply. yeah what you said is exactly correct.. it all about handling make. i use "sed" option to generate .d files and now it is recompiling without any dependency error. can you figure out how to use "sed" in different way, as in gnu make explanation for sed is obscure.ie...need some clear tutorial ?
