Technically, it doesn't. But it _does_ require AC_CONFIG_AUX_DIR, and AC_CONFIG_AUX_DIR documents that rather than probe for all possible auxiliary files, it _only_ probes for install-sh and assumes all other aux files are in the same location. Can it be improved? Probably. Maybe we could add a macro that registers a required aux file, and have AC_CONFIG_AUX_DIR probe for the first such registered file rather than hard-coding the search for install-sh. That way, using AC_CANONICAL_BUILD in isolation would then warn you about missing config.guess, rather than missing install-sh. But someone has to write the patches.

The requirement for install-sh is not mentioned. The requirement for install-sh as the hard-coded witness file was mentioned in the #Input section under AC_CONFIG_AUX_DIR. -- Eric Blake eblake@xxxxxxxxxx +1-919-301-3266 Libvirt virtualization library http://libvirt.org
