[etherlab-users] rtB not defined in RTW application

[Julian Stoev]

Thanks, this solved the compilation problem.

I use the build script from etherlab-bundle-1.6 => EtherLab 1.2-rc4
http://www.etherlab.org/download/bundle/etherlab-bundle-1.6.tar.bz2

You recommend some different version? I see rc5 is available. This is
your stable branch?
