I am currently attempting to use a version of this (non-recursive) method. I am avoiding exactly what you wrote since I need to pass specific -D options to different packages without using libA_CPPFLAGS = -DFORLIBFOO -DFORLIBBAR -DETC. What I have now is I have replaced the file names in the recursive Makefile.am's to be relative to the root directory like so: libfoo_SOURCES=src/foo.cpp -> libfoo_SOURCES=libfoo/src/foo.cpp and included libfoo/Makefile.am in the root Makefile.am. This works well, and would nearly be finished, except in my root Makefile.am I get this: noinst_LTLIBRARIES = libfoo.la ... lib_LTLIBRARIES = libA.la which Automake dutifully turns into a rule which always builds libA.la before libfoo.la, despite the fact that libA depends on libfoo (as expressed by the variable libA_la_LIBADD = -lfoo). How can I either 1. Express to automake the correct dependancy 2. Trick automake into building lib_LTLIBRARIES last (after noinst_LTLIBRARIES) ps. This would have been a lot easier if Automake would have automatically provided targets for each one of the SUBDIRS. That way I could have simply wrote one rule, libA: foo bar baz (where foo bar baz are SUBDIRs that need to be build before the SUBDIR libA). Should I open a bug/feature request? Thanks a tonne for your unheralded work!!! Id hate to have to give up on autotools. Cheers,
