[etherlab-users] rtdm compile error

[Andreas Stewering-Bone]

/Hello Ravi,

Which runtime enviroment do you use?

Xenomai/RTAI?
Kernelversion ?
Distro?

My configuration
Debian squeeze

Xenomai
Kernel 2.6.35.9
Xenomai 2.5.6

RTAI
Kernel 2.6.32.11
RTAI 3.8.1


You need the master_send_ext for using async communication like EoE,...
