Can you help please ?

To compile try adding these packages:

sudo apt-get install -y python3-six python-six libnode-dev

You should be able to install libv8 with:

sudo apt-get install -y libv8-3.14.5

However, I've been having a problem with building against libv8-3.14.5 on Debian. Recently Debian removed the libv8-dev package and replaced it with libnode-dev. libnode-dev includes libv8 but a new version with a very different interface. So recent version of CAMotics (what's on Github) require this newer version of libv8. It's a mess.

I'm thinking about including a version of the libv8 code directly in the CAMotics source tree and statically linking it into the executable to avoid this problem altogether.

Hi @jcoffland,
What's news about this?
I recently reinstall my main CNC + Dev computer with Debian Bullseye, and theresult is Camotics does not work anymore after reinstalled the camotics_1.2.0_amd64.deb package. :-(
I installed libnode-dev in place of libv8* but it doesn't work better.
What can I do to have a functional Camotics again?

You can also try this:

sudo apt-get update
sudo apt-get install -y wget
wget http://ftp.us.debian.org/debian/pool/main/libv/libv8-3.14/libv8-3.14.5_3.14.5.8-8.1_amd64.deb
wget http://ftp.us.debian.org/debian/pool/main/libv/libv8-3.14/libv8-3.14-dev_3.14.5.8-8.1_amd64.deb
sudo dpkg -i libv8-3.14.5_3.14.5.8-8.1_amd64.deb libv8-3.14-dev_3.14.5.8-8.1_amd64.deb

I tried the above but I get this from the terminal. Don't know how to get around this.

$ sudo dpkg -i libv8-3.14.5_3.14.5.8-8.1_amd64.deb libv8-3.14-dev_3.14.5.8-8.1_amd64.deb

Run this first:

sudo apt-get remove -y libnode-dev

[curnowdj266]

OK did the remove. I uninstalled camotics and reinstalled.it. I also shut down and restarted the computer and I get the terminal message below when I try to run camotics.

$ camotics
camotics: error while loading shared libraries: libQt5WebSockets.so.5: cannot open shared object file: No such file or directory

[jcoffland]

According to #322 that should be solved with this:

sudo apt-get install -y libqt5websockets5-dev
