determining targets with recursive makefiles

[Jan M]

Hi,

 

I am trying to determine the build targets of glib version 2.6.4 in order to locate an old library that may be causing build problems with gtk+-2.6.7.

 

The GNU make manual reference to recursion doesnt provide a hint as to how, with this method of recursion, make is finding the sub-makefiles and -d output doesnt provide the full sub-makefile pathname so following what is happening is difficult.

 

The 'top' makefile contains:

 

BUILT_SOURCES = stamp-gc-h #note: not glibconfig.h

 

RECURSIVE_TARGETS = ... all-recursive ...

 

all: $(BUILT_SOURCES) config.h

    $(MAKE) $(AM_MAKEFLAGS) all-recursive

 

Exactly what is happening here?

 

By what mechanism is make locating the other makefiles (cd <subdirectory> appears not to be used as in the example of recursion in the manual)?

 

What is the significance of all-recursive, which is declared but appears not to be defined?

 

I'm using make version 3.80 on Mandrake Linux 10.0.

 

Thanks,

 

Jan
