Compilar el simulador manualmente

The simulator mode is useful for playing with gcode onscreen and exploring/developing user-space software, but not for measuring jitter or driving actual machinery.

The following build steps for Ubuntu 11.10 and 12.04 will also work for Ubuntu 10.04 with one principal difference. In Ubuntu 10.04 three packages must be installed to enable the git command set.

From the Installing_LinuxCNC page,

  sudo apt-get install git-core gitk git-gui

As well, for Ubuntu 10.04 it is not necessary to remove the tcl8.4 and tk8.4 packages before compilation.

There are no precompiled packages for 11.10. These steps will make a working simulator with a fresh Ubuntu 11.10 installation.

Credit goes to Anders Wallin who made the first steps with the simulator and 11.10.

Install git. sudo apt-get install git Intall dpkg-dev. sudo apt-get install dpkg-dev Make a directory, for example git, in your favourite location. mkdir git Go into the git directory and get a copy of the LinuxCNC source. cd git git clone git://git.linuxcnc.org/git/linuxcnc.git linuxcnc

Go to the debian folder and configure cd linuxcnc/debian ./configure sim Go back to the linuxcnc folder and check dependencies cd .. dpkg-checkbuilddeps Which will output something similar to: dpkg-checkbuilddeps: Unmet dependencies: debhe... Now the dependency check threw a number of missing artifacts, install them all with apt-get.

Editor's note 1: These are the packages I had to install to get it running. This list is illustrative but dependencies may well differ for your installation---it's best explicitly to check them as shown above. sudo apt-get install libpth-dev dvipng tcl-dev tk-dev tcl8.4-dev tk8.4-dev bwidget libxaw7-dev libncurses-dev libreadline-dev asciidoc source-highlight dblatex groff python-dev python-tk python-lxml libglu1-mesa-dev libgl1-mesa-dev libgl1-mesa-swx11-dev libgtk2.0-dev libgnomeprintui2.2-dev autoconf libboost-python-dev texlive-lang-cyrillic

Editor's note 2: There can only be one libgl development package installed at the time. If there are any conflicts, remove (purge) the installed package and retry.

Editor's note 3: The apt-get install command above is almost working as is in a Ubuntu 12.04 as well. The libgl1-mesa-dev is provided in other packages, but apt-get will hint which one to install get it running. Install that package separately, remove libgl1-mesa-dev from the long install command and go for it. Please note that the extra packages needed might differ for your machine, depending on your setup and hardware.

Here's an example of a command that worked on 12.04:

When the command dpkg-checkbuilddeps returns silent you can go to next step.

If you checked out linuxcnc on ubuntu 12.04 the following step is not necessary anymore.

The tcl8.4 and tk8.4 packages are only needed to get the dependencies check working, they will conflict with the configure.

Remove them again. sudo apt-get purge tcl8.4-dev tk8.4-dev

Now it's finally time to compile linuxcnc cd src ./autogen.sh ./configure --enable-simulator

This may show other packages that must be installed. Install these and re-run configure.
Don't proceed until you get the banner message saying configure is complete.

Now you can compile with the command make

Add following to your path (such as .profile) export PATH=$PATH:[path to the linuxcnc dir]/linuxcnc/scripts

LinuxCNC can now be started with the command ../scripts/linuxcnc

Don't forget to use a simulator configuration (sim tree in the config selector).
