Linux RH7.0
Apache
PHP 4.0.3pl1
ucd-snmp 4.1.2

ucd-snmp compiled both with and without config.h hack.

php compiled with --with-apxs --with-pgsql --with-snmp AND WITH AND WITHOUT --enable-ucd-snmp-hack

No compile or runtime errors.

None of the snmp related functions return any data:

eg.

$mibs=snmpwalk("xxx.xxx.xxx.xxx","community","");
echo count($mibs);

returns "0".

when restarting apache:

PHP Warning: Unable to load dynamic library './snmp.so' - ./snmp.so: cannot open shared object file: No such file or directory in Unknown on line 0.

hope that helps!

Where is the snmp.so located in your system?
Is the path of it in /etc/ld.so.conf ??
If not, add it and run ldconfig.

For some reason, php stopped compiling altogether --with-snmp.  (perhaps due to attempting compile with most recent version of ucd-snmp?).  So......

Followed previous instructions, plus I recompiled ucd-snmp with --enable-shared

After this, php compiled fine with: --with-apxs --with-pgsql --with-snmp.

The extension_dir was not looking in the right place for snmp.so, so I set extension_dir in php.ini to "/usr/share/snmp" (location of snmp.so).

However, on restarting Apache, error in /var/log/httpd/error.log:

PHP Warning: Unable to load dynamic library '/usr/share/snmp.so' - /usr/share/snmp/snmp.so: cannot open shared object file: No such file or directory in Unknown on line 0.
[Repeated again]


Thanks...

Ooops, getting tired.....: libsnmp.so is in /usr/local/lib as you'd expect.  Changed extension_dir back to /usr/local/lib, but same problem:

 "/usr/local/lib/snmp.so: cannot open shared object file: no such file or directory in Unknown on line 0'.

You haven't compiled snmp as shared extension for PHP.
Put a ; in front of  the extension=snmp.so in php.ini.
Check that you have /usr/local/lib in /etc/ld.so.conf (if it isn't add it and run ldconfig).

Then try to start apache again.

Sorry, didn't get to you - this indeed fixed this (particular!) problem.

Thanks for your assistance.
