difficulty installing simulator Ubuntu 12.04 x64

Hello. I have installed linuxcnc on my 64 bit shop machine using ubuntu 10.04. It works fine.

I am trying to install *the simulator* on my main computer, a 64 bit supermicro with twin xeon processors. I followed the steps on wiki.linuxcnc.org/cgi-bin/wiki.pl?Build_A_Simulator_Manually

dpkg-checkbuilddeps returns silent.

upon ./configure --enable-simulator, I get:

I tried make anyway, and got:

X7DA8:~/git/linuxcnc/src$ make
Makefile:64: Makefile.inc: No such file or directory
Makefile:75: *** Makefile.inc must specify RTPREFIX and other variables. Stop.
X7DA8:~/git/linuxcnc/src$

I don't know where to start in fixing this so that I can install.

If anybody could please help me here, I surely would appreciate it.

Thanks.

try

sudo apt-get install libtk-img

Thank you!

Now it runs, but I get an error when I choose a sim configuration:

X7DA8:~/git/linuxcnc$ linuxcnc
LINUXCNC - 2.7.0~pre0
Machine configuration directory is '/home/me/git/linuxcnc/configs/sim/axis'
Machine configuration file is 'lathe.ini'
Starting LinuxCNC...
Note: Using POSIX realtime
Unexpected realtime delay on task 0
This Message will only display once per session.
Run the Latency Test and resolve before continuing.


When I try to select latency test from the GUI, the terminal gives me:

X7DA8:~/git/linuxcnc$ linuxcnc
LINUXCNC - 2.7.0~pre0
/home/me/git/linuxcnc/configs/apps/latency/latency-test.demo: line 3: /home/me/git/linuxcnc/scripts/latency-test: Permission denied

I didn't think I needed realtime for the simulator.

EDIT: Looking back, I see I did do a sudo make setuid. Previously wrote that I hadn't. I'm getting confused here. Sorry.

/home/me/git/linuxcnc/configs/apps/latency/latency-test.demo: line 3: /home/me/git/linuxcnc/scripts/latency-test: Permission denied

you found a bug that was just noticed recently:

git.linuxcnc.org/gitweb?p=linuxcnc.git;a...0b0f6c08eb1ed9d44755

you can probably fix with:

chmod 755 /home/me/git/linuxcnc/scripts/latency-test

Thank you again. That worked.

Now I can run latency test. I get horrible numbers, but I expected that since this is a server running Oracle and a webserver.

I still get the error:

X7DA8:~/git/linuxcnc$ linuxcnc
LINUXCNC - 2.7.0~pre0
Machine configuration directory is '/home/me/git/linuxcnc/configs/sim/axis'
Machine configuration file is 'lathe.ini'

Shutting down and cleaning up LinuxCNC...
Note: Using POSIX realtime
X7DA8:~/git/linuxcnc$

Is there a place in the configuration where I turn off realtime for simulation? Am I wrong thinking that I should be able to run the simulator on a machine unfit to for actual machining work?

I must be missing something here.

Thanks again.

looks like you are running master (that has uspace realtime), did you try 2.6?

Just ignore the error messages when running as a simulator and not driving any hardware.

"looks like you are running master (that has uspace realtime), did you try 2.6? "

No, I just followed the steps in wiki.linuxcnc.org/cgi-bin/wiki.pl?Build_A_Simulator_Manually
I have such a slow connection that it took days to do the install.



"Just ignore the error messages when running as a simulator and not driving any hardware. "

Oh, thanks. Some of the choices (like run program) are greyed out, but I guess I'll need to play with it some more to figure out how to run the simulator.

If you want to try 2.6 you check out that branch with
in your linuxcnc build directory (one level above src)

and then build

I'm in unknown territory here.

How do I commit or stash?

X7DA8:~/git/linuxcnc$ git checkout 2.6
error: Your local changes to the following files would be overwritten by checkout:
scripts/latency-test
Please, commit your changes or stash them before you can switch branches.
Aborting
X7DA8:~/git/linuxcnc$

EDIT: did git stash

git checkout seemed to work.

X7DA8:~/git/linuxcnc$ git checkout 2.6
Branch 2.6 set up to track remote branch 2.6 from origin.
Switched to a new branch '2.6'
