[Please follow up to debian-science]

Dear people,

first of all I would like to apologise because I have "BCC" this mail to
people that I think that use debian (or ubuntu) and has relation with the
robotics area and they are not subscribe to this list. If I'm wrong, sorry
for the noise and move this mail to /dev/null. ;-)

OTOH, if it's your case, and you know people that are interested, please, FF
this message.

John - what kind of monitor are you using?  I've found that a CRT or 
high quality LCD is needed to be able to differentiate "close" colors.  
It's possible that Chris just has a nicer monitor than you :)

Re: Bug in classicladder 7.100 EMC 2.2.6

Hi Steve,

I have a Viewsonic Monitor. The difference between 2.2.6 and 2.3 is substantial as 
far as the colors used in the classicladders grid. I think I got it backwards as 2.3 is 
much easier to see the grid than 2.2.6 (I just opened up a zillion configs :)

emc on x86_64

Hi,

Did anybody try to run emc-2.2.6 on an x86_64 kernel?
I just tried it, but it just segfaults in halcmd.
I'm not sure what happens exactly, yet. I can provide some logs
tomorrow (I'm currently not at the machine).

I tried with latest rtai, linux-2.6.24.7 and emc 2.2.6 on
a debian lenny system. Compiled with gcc 4.3.1 (afair).

Classicladder edit colours etc


Hey John, everyone

I thickened the edit mode layout line in cl 7.124-not sure I like it-see what you think.
I think I am confused about what version you liked. In CL 7.100 that is in emc 2.6 the lines are red, in CL 7.124
the lines are blue.
I use ubuntu 8.04 on a laptop for development. The blue shows up well. 
If the blue is good I will change CL 7.100 to suit.
Also I changed the tooltips to your suggestion - 'object selector'
still working on the 'save' button trouble.

Ok, here are the logs. I'm trying to start emc with the default sim/axis_mm config.
Any advise?

PS: The 24k limit for the list is too low, as you can see the required logs
are already bigger than the limit. Please consider a 100k limit.

Re: emc on x86_64

Have you followed the instructions for modifying the
/etc/security/memlock.conf file shown here?

Re: Classicladder edit colours etc

Hi Chris,

I'm sorry if I lead you down the wrong path on the lines. The thin blue lines were fine 
on my 6.06 it was the red lines that didn't show up well. I like the thin blue lines 
better than the think blue lines. 

Now the tool tips match the manual :)

Thanks for all your effort
John

Ok, no. I didn't know such documentation for lenny does exist.
I'll try that tomorrow and report whether it worked or not.

Thanks a lot, that fixed the problem. :) The mill works great now.

Isn't it possible to implement a check and exit with an error message?
Where is it segfaulting? Does the kernel segfault us if we try to memlock
a range bigger than the allowed one? Or does it crash due to some NULL
pointer deref later?
