This is more of an automake question than an autoconf one (since it is automake that generates the make rules for what needs to be rebuilt when). Do you have AC_CONFIG_MACRO_DIR([...]) in your configure.ac, pointing to the location of your .m4 files? Likewise, in your Makefile.am, do you have ACLOCAL_AMFLAGS = -I path/to/m4? I've found in my projects that both places are needed to inform automake that it must generate proper dependency tracking so that a change to a .m4 file forces an automatic autoreconf. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
