Re: [RTnet-developers] Running an RTNET node over a non-rt network.

[Saiful K. <sai...@gm...>]

Hi Gilles,

I have some confusions
1. U changed the protocol stack only, so it will work in nonRT linux
over nonRTDM driver rite?
2. Then can the real time performance be achieved?
3. Can u please tell me how to use/install it in nonRT linux? (as when
after patching i tried to configure using ./configure then I got
error: checking for RT-extension... configure: error: *** RT-extended
kernel not found in /lib/modules/2.6.20/build)

Sorry if I asked any invalid questions.

Thanks and regards
Saiful
