Platform- and misc. Questions

Hi group!
a Student of mine is trying to set up EMC for a Hexapod that is run by Stepper
Motors.
We had quite some trouble finding a Version of RTlinux and RedHat and EMC that
fit together and compile well.
One Problem is that the sources on the NIST website are out of date. Maybe there
should better be a link to the sources on sourceforge. They seem to be quite
complete.
Then we had some trouble compiling the whole stuff again after writing new
kinematics files. These scripts and the makefiles are quite tricky and i do not
fully understand them. So when I wanted to compile my kinematics functions, I
always used to run the compile script right at the /usr/local - level. This took
some time but worked well. I newer versions there is no compile script at this
level. We took some from the /scripts directory but they didnt result in full
/plat-stuff. What would you suggest?
After we had successfully done that in a version of February 2000 for our
Hexapod, we were able to reference the axes in Axis-Mode and run G0 Z20 in
MDI-Mode. The Steppers moved as expexted. Then we wanted to tune the Step per mm
-ratio and these changes to the ini-file caused the communication to fail. Is
this a known effect? When the processor is overloaded with motion tasks does
this cause problems with the communication?
With G50 and G51 You can choose between inch and mm, i think. The default status
is inch in emc. How can I change this default to mm?
We had the effect that yemc sometimes worked and sometimes didnt is it unstable
or are we causing this by something in our .ini?
In some recent mails you talk of tkemc as a possible hexapod gui. Can we
visualize 6 axes with some new version of tkemc? Where can i find it? Which
redhat, which linux/real-time-linux/emc do i have to choose to make it work?
