Unable to compile SNMP in PHP5.2.8

[TheCodeman]

Hey guys, hoping you can help me out with a recent problem.

This morning I set about installing Cacti, haven't had much success and it appears that the problem is likely that SNMP is not compiled in PHP. (I do have snmp & snmpd installed via the apt-get system.)

So, I set about recompiling PHP with the "--with-snmp" flag, but I get the following error:

checking for SNMP support... yes
checking OpenSSL dir for SNMP... no
checking whether to enable UCD SNMP hack... no
checking for net-snmp-config... /usr/bin/net-snmp-config
checking for snmp_parse_oid in -lnetsnmp... no
checking for init_snmp in -lnetsnmp... no
configure: error: SNMP sanity check failed. Please check config.log for more information.

The config.log shows the following

configure:87422: checking for SNMP support
configure:87469: checking OpenSSL dir for SNMP

char init_snmp();

int main() {
init_snmp()
; return 0; }

Which isn't telling me much more, basically looks like the problem is with /usr/bin/ld: cannot find -lnetsnmp...but I have no idea how to proceed from here.



Thanks for the help!

I'm not sure I know better than The Codeman, but it looks like you are missing some library. Have you Googled the error message? Find out which development package contains the missing library and apt-get it.
