[yocto] net-snmp_5.8.bb failed to compile

[Simon Chamlian]

Will the following method work?

yocto-layer create openembedded*2*

and add the path in conf/bblayers.conf

By doing this, I will have
openembedded   where  net-snmp version 5.7.3 resides
openembedded*2*  where  net-snmp version 5.8   resides


Then issuing bitbake net-snmp it will take the 5.8?
