Hi Jonathan Wakely,

Thanks for your kind first step. I should have made my question more clearer.

We have a module called abc. Amazingly user can just define abc_type, abc_target; and GNU make seems to me that  according to its rules will implicitly look for these bars if defined. Does the same doc have these rules description?

Thanks
Ming

Hi,

In a .mk makefile, there are these kinds of lines:
modules := abc  xyz
abc_type := static_library
abc_target := libabc.a


I know traditional Makefile format(simple usage). Where can find these "new" format guide?

GCC requires GNU Make. This syntax is documented in the GNU Make manual:
