I will post report as soon as network will be working again on the EMC machine
complete install is "by-the-manual" found on the webpages, so... I cannot remember if the RTAI was built from source :-( OK, I found the manual - so, I did compile something, but the magma core is from the ubuntu repository, so I think I did not compile that one. http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Installing_EMC2#On_Ubuntu_5_10_and_6_06_from_source 3.2. Getting the source with CVS EMC2 source is stored in a system called CVS. To get the latest released version of emc2, cvs -z5 -d:ext:[EMAIL PROTECTED]:/cvs co -rRELEASE_2_0_5 -d emc2-2.0.5 emc2 I am confused now. I vaguely remember that some installer asked me about getting RTAI too, and I still can not remember how this happened... maybe because I got a very bad cold now. Hours and hours of rtai/kern latency tests :-) I may send the script and some results as soon as I get the network working.
