and another. I'm pretty sure I could expose the colors to the Hal_gremlin widget so users could change them
but I'm not sure whether its worth it...

Nice work! Trying to get it going now.

( This was a post asking for a tutorial, but then I found the Linux CNC git wiki and the fog lifted...)

Edit... And I am back.
Please help me with a detailed guide to setup Gscreen from a fresh live cd ISO image install of LinuxCNC 2.5
(i am listing every step so that it may help other complete noobs too...) please correct where wrong.
$ su

$ sudo apt-get install git-core gitk git-gui
$ git clone git://git.linuxcnc.org/git/linuxcnc.git linuxcnc-dev


cd to linuxcnc-dev directory
$ git reset --hard remotes/origin/master
$ git pull origin master
$ git pull git://git.mah.priv.at/emc2-dev.git gscreen_master
$ apt-get install libboost-python-dev
$ cd src
$ ./autogen.sh
$ ./configure
$ make
$ make install-menus
$ make setuid
$ . ./scripts/rip-environment
$ linuxcnc

wonderfull, I now have 2.6pre running from the Linuxcnc-dev folders. but if I go to the Applications,CNC LinuxCNC it still launches Linuxcnc2.5
I cannot edit any of the sample configs for 2.6
I ran stepconf from usr/bin, which created a desktop icon(which .ini i changed from AXIS to gscreen for my machine but this does not load 2.6

How do i get this new version to replace and function exactly as the old 2.5 did?

or am I missing a whole lot about how to actually install gscreen...

Thanks

Did you build from source? Did you remember "sudo make setuid"?

Post no #21564 list exactly what i did step by step. I assume this is build from source. As i did the steps in terminal i wrote it in the post...

My linux skills don't go much beyond reading the wiki and doing the steps...
Thanks

You need to sudo the make setuid step.
(And it appears that you didn't).

sudo make setuid

it will ask for your password.
Do you see a linuxcnc (run-in-place) under Applications/cnc ?

if no then you will always have to run linuxcnc from the terminal and enter . scripts/rip-environment once before running it the first time.

the command make install-menus is supposed to add the run-in-place entries - it didnn't seem to work for me.

Also note if using the linuxcnc launcher, if you look under sample configurations / sim you will find three gscreen examples that will run with no hardware.

The make install-menus command does not seem to work.
Also when I run sudo make setuid, the process completes, but if i close the terminal and open a new terminal and type linuxcnc it still launches 2.5, i cannot get it to launch 2.6pre ...
I am stuck.

If I do the rip-environment thing it works and I can get the gscreen sample program to run.

I really want it to run just like the original live cd from the applications menu. How do I accomplish this?

Also is anybody working on a touchscreen pendant control? I was hoping that under jogging mode button you would get an onscreen pendant style jogging controller similar to what Mach3 has...

Thanks for the support.
