Hi Marc,
ich habe gerade die aktuelle CVS-Version von RTnet heruntergeladen und
damit ist das beschriebene Problem mit DESTDIR-installiertem RTAI3
verschwunden. Viiilen Dank.
Und entschuldige bitte die spaete Reaktion. Ich bin erst jetzt zum
Testen gekommen.
Bist Du bzw. seid Ihr naechste Woche auch auf der Embedded World? Dann
trifft man sich ja vielleicht mal!?
Ciao, Wolfgang.
