Hi All,
I have generated mfd files for ETHTOOL-MIB following the example of
http://vincent.bernat.im/en/blog/2012-extending-netsnmp.html.
I did the changes on my files as he had done.
And used the following command for compiling subagent
net-snmp-config --compile-subagent mysub ethtoolStatTable.c
I got the following error :
generating the temporary code file: netsnmptmp.3771.c
void init_ethtoolStatTable(void);
checking for init_ethtoolStatTable in ethtoolStatTable.c
init_ethtoolStatTable(void)

} /* init_ethtoolStatTable */

removing the temporary code file: netsnmptmp.3771.c
I believe it has to do with ethtoolStatTable.h config commands

Should i change the path in config_require?
I tried by using
config_require(ethtoolStatTable_interface)
config_require(ethtoolStatTable_data_access)
config_require(ethtoolStatTable_data_get)
config_require(ethtoolStatTable_data_set)
and also by including the folder where all files including defaults
reside(ethtool1) :
config_require(ethtool1/ethtoolStatTable_interface)
config_require(ethtool1/ethtoolStatTable_data_access)
config_require(ethtool1/ethtoolStatTable_data_get)
config_require(ethtool1/ethtoolStatTable_data_set)
Its all giving the same error finally.
Have I missed out changing anything else??
Thanks
