It looks like some of the m4 files incorrectly implement the AC_ARG_WITH when there is no argument. Looking at the autoconf manual the 4th argument should be the block to run if there is no action set (e.g. no --with-xml on the configure). This was included inside of the 3rd argument previously and this was the part that was failing on the builds, because it was not being executed.
The second problem was using AC_MSG_ERROR instead of AC_MSG_WARN for the xml2 check and it would fail/stop if xml2 was not found. autoconf section 15.2: http://www.gnu.org/savannah-checkouts/gnu/autoconf/manual/autoconf-2.69/html_node/External-Software.html#External-Software -Bryan On Sep 7, 2013, at 8:25 PM, James Peach <jpe...@apache.org> wrote: > On Sep 7, 2013, at 5:00 PM, Nick Kew <n...@apache.org> wrote: > >> >> On 7 Sep 2013, at 01:35, Nick Kew wrote: >> >>>> Something in these commits breaks the builds completely.
