Thanks for the info. I was able to link with the .a files generated as you indicated.
Because I need to run net-snmp internally via init_master_agent I have to call init_mib_modules. However, even though init_mib_modules is in libnetsnmpmibs.a when I include it as a library in my link I get an undefined reference to `init_mib_modules()' So what is the reason that I am not able to call this function yet I can call init_master_agent? I am also unable to call init_udp, init_tcp etc.. Any info on this would be greatly appreciated. thanks -----Original Message----- From: Vincent Bernat [mailto:ber...@luffy.cx] Sent: Tuesday, June 16, 2009 12:29 PM To: Joan Landry Cc: net-snmp-users@lists.sourceforge.net Subject: Re: Port to embedded platform OoO Peu avant le début de l'après-midi du mardi 16 juin 2009, vers 13:57, "Joan Landry" <joan.lan...@overturenetworks.com> disait : > I am trying to port net-snmp to an embedded platform and have been > able to use ./configure and make to cross compile the code.

Those files are used by libtool. Do you want to statically link your program to those libraries (you would then need .a) or dynamically (you would need .so). You can also use libtool to achieve this. > Can anyone tell me where I can find an example of this?

Therefore, you can just link to libnetsnmp.a and libnetsnmpagent.a. Depending on what you use in your agent, you may also need libnetsnmphelpers.a. However, the easiest way to do this is to link everything. If you statically link libraries, only needed bits will be included. Otherwise, use --as-needed flag of ld (or -Wl,--as-needed with gcc). -- MUD IS NOT ONE OF THE 4 FOOD GROUPS MUD IS NOT ONE OF THE 4 FOOD GROUPS MUD IS NOT ONE OF THE 4 FOOD GROUPS -+- Bart Simpson on chalkboard in episode 9F15 ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects _______________________________________________ Net-snmp-users mailing list Net-snmp-users@lists.sourceforge.net Please see the following page to unsubscribe or change other options: https://lists.sourceforge.net/lists/listinfo/net-snmp-users
