There should be no problem using AC_CONFIG_FILES conditionally. For example: % cat >configure.ac <<'EOF' AC_INIT([test], [0]) AC_ARG_ENABLE([foo]) AS_IF([test x"$enable_foo" = x"yes"], [AC_CONFIG_FILES([foo])]) AC_CONFIG_FILES([bar]) AC_OUTPUT EOF % autoconf % ./configure --disable-foo configure: creating ./config.status config.status: creating bar % ./configure --enable-foo configure: creating ./config.status config.status: creating foo config.status: creating bar Hope that helps, Nick
