Hi Sanjeev,
With much help from Dave Shield, I recently completed a port of netSNMP 5.1.1 to an embedded ARM system (XScale). I have attached a few files that
I used for configuration, etc.
cfg.sh is just a simple script where I setup all my config options. It should contain paths to your toolchain, library paths, etc.
route_patch.h is a file that I cobbled together to get around broken dependencies with the toochain I was using. You may or may not need it. If you do, stick it in agent/mibgroup/mibII. You'll need to edit include/net-snmp/net-snmp-config.h. Find the line "HAVE_NET_ROUTE_H" and comment this out. Any files in mibII that have this conditional define should be edited to include route_patch.h rather than route.h.
Also, if you're targetting a big-endian system, I found that I needed to edit libtool (in the root directory of net-snmp). Somewhere around line 1045 of this automatically generated file, there will be a line like :
compile_command = "$nonopt"
I modified this line to be :
compile_command = "$nonopt -mbig-endian"
Robert Story was rather alarmed by this previous change, but since it worked for me, I never bothered digging deeper for the true source of the problem :)
Ciao Steve Comfort
