My notes on compiling LiteX-CNC on linuxCNC

It does a little more this time:

root@mill:/# halrun
halcmd: loadrt litexcnc
Refusing to run as root without fallback UID specified
To run under a debugger with I/O, use e.g.,
    sudo env RTAPI_UID=`id -u` RTAPI_FIFO_PATH=$HOME/.rtapi_fifo gdb /usr/bin/rtapi_app
<stdin>:1: waitpid failed /usr/bin/rtapi_app litexcnc
<stdin>:1: /usr/bin/rtapi_app exited without becoming ready
<stdin>:1: insmod for litexcnc failed, returned -1
halcmd: quit
Refusing to run as root without fallback UID specified
To run under a debugger with I/O, use e.g.,
    sudo env RTAPI_UID=`id -u` RTAPI_FIFO_PATH=$HOME/.rtapi_fifo gdb /usr/bin/rtapi_app
root@mill:/#

I guess I have a manual to read before proceeding further.

Problem is, your logged in as root. Create a user and login to that user and try again.

Thanks, that worked:

cedric@mill:~$ halrun
halcmd: loadrt litexcnc
Note: Using POSIX realtime
litexcnc: Loading Litex CNC driver version 1.0.0
halcmd: exit
litexcnc: LitexCNC driver unloaded

I tried to compile the gateware for the FPGA, but I got this error:

sudo apt-get install wget
sudo apt-get install python3-pip

wget raw.githubusercontent.com/enjoy-digital/...aster/litex_setup.py

python3 litex_setup.py --init --install --config=standard --gcc=riscv

I've restored my virtual machine, so it's a fresh install of linuxcnc again. I get the same error:

$ sudo apt-get install wget
$ sudo apt-get install python3-pip
$ sudo apt-get install git
$ pip3 install --user meson ninja

Can you verify:
- that pydantic is in requirements.txt
- that 'pip install -r requirements.txt' has been run
- you're in the correct branch (stepgen_improvement)

I've got the feeling that Pydantic is missing somehow.
