Nice. I will have to look into that one. > For me, this approach works just fine.

Indeed, this is my understanding also. > But you need not to move your sources, though. Hrm. Interesting. We did move the MPI sources into the separate subdir with the new Makefile. How did you avoid moving the sources too? Did you just prefix all of the filenames, etc. in your subdir/Makefile.am with "../"? i.e. foo_CFLAGS = $(PTHREAD_CFLAGS) foo_SOURCES = ../parser.c ../cfg.c ../foo.c ../parser.h ../platform.h foo_LDFLAGS := $(PTHREAD_CFLAGS) foo_LDADD := $(LIBREADLINE) libbar.a $(PTHREAD_LIBS) foo_DEPENDENCIES := libbar.a Cheers, b.
