If configure.ac does not contain a call to AC_OUTPUT, Automake does not fail as expected when file(s) specified in calls to macros AC_LIBSOURCE and/or AC_LIBSOURCES do not exist. See the attached test script.
Now, while the lack of AC_OUTPUT in configure.ac is almost surely a user error, IMHO it shouldn't prevent Automake from warning about other errors (in this case, the non-existence of files specified in calls to macros AC_LIBSOURCE and AC_LIBSOURCES). Regards, Stefano
