That's right, then you have to connect up to the pins you want to monitor in your hal file.
Hopefully it is all explained in the zip, been a long time since I used it myself

There seem to be more problems with the path as I get this error when I connect through HAL. I cannot compile the client either. It does not find the hiredis.h file

That's the problem, symlink that name to liblinuxcnchal.so.0 (or whatever it is called)
The branding name change caused lots of problems which I sidestepped completely with symlinks which enabled me to continue as before.
(I still type in emc at the commandline and don't get a warning because I have a symlink called emc which points to linuxcnc - 3 letters or 8 - no brainer )

It works with the symlink. I would like to get the stuff to compile later but for now it does well.
What am I supposed to see in the textboxes on the form?

See the halview_README file in the zip
Basically, whatever signals you have linked the pins to, the values of the out pins attached to those signals will be displayed.
I wrote it when I was testing a toolchanger component and trying to get particular homing behaviour at start up. This meant having to stop and re-start lcnc over and over again and I was getting sick of opening up a window to watch pins every single time I did it.

That is exactly why I am excited about this tool. I hate the constant restart while you are testing new stuff.
I get the values displayed like this "1 = 125.0000" in the label field but the text box us empty. I does not really bother me, I just wanted to know what the intended contents were. As long as I can see the values somewhere.

OK I read the info in the zip file. The net name should be displayed but mine is blank. Is there a special way to write the net name?

I think you mean the text box next to the field display.
It is just a text box, click on it and you can type whatever you like in there, as a reminder of what you are looking at.
It does not fill itself in.
I am guilty of the usual programmers error, being so familiar with the program that it all seems obvious so I don't explain it properly

Hi
I am on this boat again. I compiled and installed redis and hiredis without issues but now I cannot get the redisclient.comp to compile. The error is that it cannot find the header file. I did an export to include the location in the path.
What am I missing again?
