RE: recursive automake w/o recursive autoconf?

[Jay K]

Ok, I found the subtlety in the documentation that automake
in effect uses autoconf's directory or output list.


So if I give up non-recursive make, and if I list directories twice,
then it works nicely:


i.e. non-recursive make, less modular automake:
http://github.com/jaykrell/j/tree/master/auto1


 recursive make, more modular automake, have to list directories 
 twice; once is almost enough, but you need to tell automake the 
directories for the recursion to occur -- could almost hand-write 
 the top level Makefile instead: 
 http://github.com/jaykrell/j/tree/master/auto2 


 Ideal would be to say dirs=prog lib, instead of output prog/makefile 
lib/makefile,
 and ideally would get faster non-recursive make.


That is, auto1 has ideal performance, non-ideal, less-modular authoring.
auto2 has non-ideal performance and close to ideal authoring.


Advise?


Thank you,
