16:38 ohkay, so, make works by comparing the output file to the prerequisite file, and if the output file is out of date, it runs that. ohkay. i had the wrong-ish idea that it tracks only the prerequisites for the changes

Thank you so much for such clear explanation on makefile. You make it clear to me

4:08 simple expansion
hmm, nice. the thing is that the "verbatim assignment" is not that verbatim, the variables are evaluated there too...
but simple expansion somehow expands them differently
like i was doing += i.e. append to, and a space was being added, so, i did `VAR = $(VAR)-append` and it didn't work due to cyclicity, while := worked here

*edit:* ref: gnu > make > manual > Flavors or `info make` > 6.2 *"The Two Flavors of Variables"*
* verbatim means that the whole expression is assigned, i.e. the _LHS_ is *"set"* to the _RHS_ expression as verbatim, and acts as a container or say as a shortcut. so, when the _LHS_ is used somewhere else, it is expanded recursively, i.e. first first to the verbatim expression, then that expression is further expanded and so on.
* the simple expansion is what is the normal assignment in other languages does, i.e. the _RHS_ expression is evaluated right away, and then assigned to _LHS_

Thx a lot! After this video I finally was able to get my makefile to do what I wanted!

Thanks very much for this lecture on Makefile - I have surely gained further insight on Make but with respect to the template file given - I am not too clear on what if I have .h files in the folder - would the include $(wildcard $(DEPFILES)) take care of all . h files ?

Is it possible for you to upload the slides. That would be awesome.

Very low voice. Can't hear at all.
