LTT with RTAI-3.1

[a.astafyef at ulstu.ru]

Hi!
Does anybody know about LTT support in RTAI-3.1?
It's written, that RTAI-3.x shouldn't be patched with LTT patch (LTT is
supported by default). But when I configured RTAI this
error has appeared:

configure: error: Missing LTT support in kernel to enable trace support.
make[1]: *** [config.status] Error 1
make[1]: Leaving directory `/usr/src/rtai-3.1'
make: *** [gconfig] Error 2

Please tell me where can I get this PATCH??? Or what should I do?

Thank you!
