About Building from Source

[summerlotus513]

when i build machinekit-hal from source, refer to the steps given in the readme

git clone https://github.com/machinekit/machinekit-hal.git
cd machinekit-hal
mkdir build
cmake -S . -B ./build
cmake --build ./build
sudo cmake --build ./build --target setuid
cmake --build ./build --target binary_tree_venv
cd build
direnw allow
halrun

The command direnw can't seem to find it. I can find direnv in my system

and, I also got the following error

1. Could not find PYPROJECT_BUILD using the following names: pyproject-build
2. Could not find YAPPS2 using the following names: yapps2

This is a typo. It surely should be the direnv. Thinking about it, maybe the whole mentioning of direnv in the README is superfluous. It is useful for multiple builds and directories, to quickly switch between them. But it is a bit harder to set up and for normal user not necessary.

and, I also got the following error

Do you have the Machinekit dependencies repository installed?

yes i use direnv
The error is because I am using ubuntu18.04, I have upgraded my system to 20.04, everything is ok, I can already use halrun.
By the way, after machinekit-hal is separated from machinekit, the whole architecture is clearer, which is great.
But I still want to use the GUI program to control (no way, the teacher asked us to do this),
I have tested the remote control scheme on machinekit before (using cetus, configserver + mkwrapper) and am very satisfied. Using machinekit-hal I can't seem to find any matching gui programs (EMCApplication, cetus neither seem to work), and even with configserver removed from machinekit-hal, mkwrapper doesn't work (ModuleNotFoundError: No module named 'linuxcnc').

So, what kind of GUI program should I use locally? What should I do if I want to use remote control?
Thank you very much~
