Thanks Rasmus - problem solved here. Your corrections to
ext/snmp/config.m4
worked an should be added to the source (if they have not already).
Though your advise to the original poster, did not help him it cured a
box of mine
where I previously had SNMP functions compiled into a php apache module.
Upgrading the ucd-snmp packages, gave ssl support which php did not like
too much.
system:
php-4.0.2.tar.gz
RedHat-6.2 with some rebuilt src.rpm's from RedHat-7.1:
openssl-perl-0.9.6-3, openssl-0.9.6-3, ucd-snmp-4.2-12,
ucd-snmp-utils-4.2-12
openssl-python-0.9.6-3, ucd-snmp-devel-4.2-12, openssl-devel-0.9.6-3
config.nice - used to locate the error:
#! /bin/sh
#
# Created by configure
"./configure" \
"--with-openssl" \
"--with-snmp" \
"--enable-ucd-snmp-hack" \
"$@"
debug.log - with errors:
CONFIGURE: './configure' '--with-openssl' '--with-snmp'
'--enable-ucd-snmp-hack'

and running ./buildconf solved the problem, and gave a working php
executable.
Then the full configuration was run like this:
> debug.log && \
> config.cache && \
> config.log && \
rm -f config.cache && \
./configure \
--with-openssl \
--with-snmp \
--enable-ucd-snmp-hack \
--with-apxs \
--with-mysql=/usr/local/mysql \
--with-msql=/usr/local/Hughes \
--with-gd=shared && \
make clean && \
make && \
make install && \
echo SUCCESS
which succeded with an empty debug.log, and apache could now started
cleanly.
Thanks again.
