error: _tkinter.TclError: can't find Img - Solved

Hello,

I just installed the simulator on Ubuntu 14.04 on an intel 64 bit server. I am looking to just get backplots as I build a micromilling machine. So on this server I am just looking to use axis.

I get the startup menu, click on simulator: axis, some windows pop up for a second or less, and I get:

LINUXCNC - 2.8.0~pre1

So I tried installing img two times:

len@len-X7DA8:~/git/linuxcnc$ sudo apt-get install libtk-img
[sudo] password for len:

Reading state information... Done
libtk-img is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.

len@len-X7DA8:~/git/linuxcnc$ sudo apt-get install libtk8.5-img
[sudo] password for len:

Building dependency tree
Reading state information... Done
E: Unable to locate package libtk8.5-img
E: Couldn't find any package by regex 'libtk8.5-img'


Please, what am I doing wrong?

EDIT:
Maybe I didn't give enough information:

It was working fine in Ubuntu 12.04, but then I upgraded the system to 14.04. So I fetched the latest from Git and reinstalled. First I needed to install tcl and tk 8.6 to pass the preinstall, but then upon install I needed to remove them and install the 8.5 devs. So the tcl/tk might be messed up somehow.

Okay, solved.

After trying *everything*, the last thing I tried finally did the trick.

The problem seems to be that I have Anaconda installed. I tried upgrading it to Python 3.4, but had more tcl problems, so I did the trick of starting it in 2.7 Python mode. When I did, I saw that the Anaconda version of python is a Red Hat version. Oops.

So I went to .bashrc and removed the references that start python from anaconda instead of Trusty Tahr's version. After that I did a plain vanilla install, without any special tags denoting tcl or tk. By then, linux knew which directory to search and so on from previous tries.

I didn't bother doing a setuid because it's just a simulator and I wished to keep the install as uncomplex as possible.

So here is what worked:

python ' checked the version of python
less .bashrc ' looked for ananconda's links
gksudo gedit .bashrc 'removed anaconda launch of python
**************** logged out, then logged back in
cd git/linuxcnc/debian
./configure sim
cd ..
dpkg-checkbuilddeps
cd src
./autogen.sh
./configure --enable-simulator
make clean
make
cd ..
linuxcnc

I hope this helps someone else.
