Could you past the last 20 lines or so, from config.log?

Also the output of sablot-config --libs please. My guess is you have iconv installed and Sablotron picked up on it. Could you confirm that?

Seems like youre on the right track.

This actually is snmp problem, it doesn't have any test
that the selected libs actually work..I'm on it.

Please try the next stable snapshot from http://snaps.php.net/ in about 2 hours.

Tried with php4-STABLE-200302180830.

Now I get a different error:

Im running OpenSSL 0.9.7

Could you move this to a relevant category?

Best regards Henrik

Recategorizing.

Sniper's fix works: it points to the correct problem :)
From the looks of this, you have a problem in your libsmnp library. Try recompiling it and could you mention which snmp package this is? Is this the ports version and if so, which exact version (ls -al /var/db/pkg | grep snmp)?

The SNMP package is ucd-snmp-4.2.6.

I compiled this from source with the following:
./configure --prefix=/usr/local --with-persistent-directory=/var/run/ucd-snmp --with-sys-contact="email@example.com" --with-sys-location=Unknown --with-logfile=/var/log/snmpd.log --with-openssl=/usr

I use this for my MRTG, without SSL though.

Updated description.

The des* interfaces are from openssl. Is 4.7-stable using openssl 0.9.7 already, or did you compile that yourself?
If it is, I'll cvsup my box and try to replicate your problem - unable to reproduce it, with system supplied openssl 0.9.6g and ucd-snmp-4.2.5_2 port.

It looks like a problem outside of php though (snmp/openssl linking), but I'd like to replicate this first to be sure.

OpenSSL 0.9.7 is in FreeBSD 4.7-stable

From /usr/src/UPDATEING:
20030214: OpenSSL 0.97 has been imported, and the libcrypto/libssl library versions have been bumped.

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions. 

Thank you for your interest in PHP.

Confirmed that this is not a bug in PHP. With today's  
cvsup'd system, you cannot even compile the ports version  
of ucd-snmp anymore. Version 2.4.6 you can compile, simply  
because it ignores the error, but it doesn't create a 
library. I guess you installed 2.4.6 version before 
upgrading your system? 
  
This issue is with openssl 0.9.7, which changed the des  
interfaces. Compiling the ports version (cvsup'd as well)  
ends with the following error:

I'm afraid you'll have to wait until somebody fixes the  
openssl issues in the ports collection :(. 

Just a little side note.

I upgraded to NET-SNMP 5.0.7, and all semed to work.
