In order to reduce the memory footprint (for instance, to
embed the snmpd into a device), the following configure options
could be used.

'--disable-debugging'
This turns off the compilation of all debugging statements.

'--enable-mini-agent' '--with-out-mib-modules=examples/ucdDemoPublic'
This creates an agent with just the essential MIB modules included.
NOTE: If you need additional MIB modules, then simply add them
using the option <CODE>'--with-mib-modules=...'</CODE> but this will of course
increase the memory footprint.

'--with-transports=UDP'
This option specifies the transport domains to include.
For a simple standalone agent, just UDP should be sufficient.
(Although the <CODE>'disman'</CODE> and <CODE>'agentx'</CODE> modules may require the
Callback, TCP and/or Unix transport domains as well).

'--without-kmem-usage'
This can be used in order to omit the code that operates on the
/dev/kmem interface. Clearly, this option cannot be used when
one of the configured MIB modules depends on it.

'--with-mibdirs=' and '--with-mibs='
These options tell the agent not to load any MIB modules.
This doesn't affect the size of libraries or application
binaries, but will reduce the memory footprint during runtime.

'--disable-mib-loading'
This can be used in order to omit the code that loads and
parses the MIB files altogether. This will reduce both the
runtime memory footprint, and the binary sizes.

Once the agent (snmpd) has been linked, you might also try running
<CODE>'strip snmpd'</CODE> to remove un-necessary debug/symbol information.

		+	Net-SNMP version 5.7 adds some additional features for removing unneeded code. You can enable these features by using:
		+
		+	'--enable-minimialist'
		+	This removes any unneeded code from the compiled instance. See the [[Feature Marking and Selection]] page for details on this feature.
		+
		+	'--enable-read-only'
		+	This turns of SNMP SET support for the entire package if you don't need to support an agent that allows configuration directives to be sent to it.
