what is gendep?

what is gendep? it build开发者_开发问答s dependencies, how? any good book to read about this entire gnu make gamut?

Not an expert by any means, but it appears to look at the system calls to open() that a particular binary makes and looks to see if the opened file matches a particular regular expression. If it finds a match, it records this match in a file GNU make can parse.

As far as GNU make, I know there's an O'Reilly book out there on the subject but this free tutorial does a good job going over the basics: http://www.gnu.org/software/make/manual/make.html
