Compiling PHP with SNMP - SNMP sanity check failed

mossy464

Hi,

Iv been trying to compile php with snmp support for the past week and its driving me nuts.

I am on a linux machine and after seeing some guides around I installed net-snmp, open-ssl, apache with no problems and now when i go to try and compile php with snmp, i get snmp sanity check failed error.

Here is my configure script for php:

cd /usr/local/src/php-5.3.2/

./configure --prefix=/usr/local/php --with-snmp=/usr/local/include/net-snmp --with-apxs2=/usr/local/apache2/bin/apxs --with-openssl=/usr/local/ssl --enable-ucd-snmp-hack  

Can anyone help me on this one? Im already after spending too much time on it but I need it working for my college FYP. Any help much appreciated.

Thanks

What flavour of Linux? Can you post the error message?

mossy464

Using openSuse 11.1

Here is the final few lines showing the error.

checking for SNMP support... yes
checking OpenSSL dir for SNMP... no
checking whether to enable UCD SNMP hack... yes
checking for default_store.h... no

checking for kstat_read in -lkstat... no
checking for snmp_parse_oid in -lsnmp... no
checking for init_snmp in -lsnmp... no
configure: error: SNMP sanity check failed. Please check config.log for more information.

WizZard

And what does config.log show???

WizZard

Is there any reason you want to compile yourself as opposed to using pre-built packages for OpenSUSE? e.g. php5-snmp

mossy464

Config.log shows:

Have you installed the devel (headers) for net-snmp? I'm not familiar with OpenSUSE so not sure what it's called. It's often/usually net-snmp-devel

mossy464

That could be it. I'll check there. Thanks

mossy464

It turns out i didnt have the devel headers installed for net-snmp. I installed them and the configure worked but then when i did a make I got a series of errors. See below. There was more besides these. Just giving u the last few

/usr/local/src/php-5.3.2/ext/snmp/snmp.c:1179: error: ‘SNMP_DEFAULT_TIMEOUT’ undeclared (first use in this function)
/usr/local/src/php-5.3.2/ext/snmp/snmp.c:1180: error: ‘SNMP_DEFAULT_RETRIES’ undeclared (first use in this function)

/usr/local/src/php-5.3.2/ext/snmp/snmp.c:1208: error: ‘SNMP_VERSION_3’ undeclared (first use in this function)
make: *** [ext/snmp/snmp.lo] Error 1

WizZard

You'll also need snmp-libs and snmp-devel.

Again, is there a specific reason you want to compile yourself vs using pre-built packages for your OS?

mossy464

Well I was told that net-snmp would be the best to use. I'll check if I have the snmp-libs and snmp-devel and try that.

If all comes to all I will just install the php-snmp module

WizZard

Do you have net-snmp-libs installed? Are you sure it's in /usr/local/include/net-snmp ?

mossy464

Yes, I have net-snmp-libs installed as far as i know. In the software manager i have installed every available net-snmp component. There isnt one called net-snmp-libs but one called libsnmp15 and its described as shared libraries from net-snmp.

As far as /usr/local/include/net-snmp is concerned im not sure about this, i just put this in as this is the dir where there are a lot of net-snmp header files and stuff.

mossy464

Ok iv given up on using net-snmp but now having problems with php5-snmp.

I have installed the lamp package and the php5-snmp module using the package manager in opensuse then in the htdocs folder for apache i put in a little php script i wrote with snmp commands in it and i named it index.php but its just giving me a blank page .

WizZard

What's appearing in the PHP logs (error_log)?
Is snmp appearing in phpinfo()?

Iv removed it again. Im starting from scratch installing everything.

Any way you can guide me through it please? I must be making a mistake somewhere.

Its so frustrating, the amount of time iv been trying to sort this out.

Iv moved onto my ubuntu virtual machine now.

WizZard

Follow this guide to install LAMP on Ubuntu https://help.ubuntu.com/community/ApacheMySQLPHP

Also install the php5-snmp package.

That should work ok (assuming your Ubuntu install is clean)

mossy464

Cheers, i'll try this. So follow the lamp install guide.

Then install php5-snmp through synaptic package manager?

WizZard

Yes. The guide will give you a fully working LAMP install (assuming you need the M[ySQL] also), and then

sudo apt-get install php5-snmp

will install the snmp module for PHP.

Verify it's installed correctly by checking phpinfo - create a new file in your web-root with the following content:

<?
phpinfo();
?>

Save as phpinfo.php and navigate to http://localhost/phpinfo.php to view it. You should see an snmp section like in the attached (partial) screenshot.

Thank you very much for this. I will post how i get on

mossy464

Thank you so much. Its working. Finally.

Many thanks for your help and patience wizZard.

WizZard

You're welcome. Glad to be of some help.
