source files several levels deep

[G.L. Grobe]

I'm still quite new but beleive I've got the basics down. Anyone give me some advice on how to compile files in directories several levels deep?

 

TopLevelDir

   |- Makefile

   |- DirectoryA       // contains no source

        |- SubDir1ofA    // contains source files

        |- SubDir2ofA    // contains sourse files|

 

I used to have a makefile in DirectoryA that handled all of it's subdirs before I switched to autoconf and would now like to do something equal and not put everything in the toplevel makefile.

 

Any help/advice much appreciated.
