Raspberry Pi 4 Tutorial - fatal error

On another side note: I had my first ESD incident with the rpi4 yesterday. I woke up early came into the office sat down to start working on the issue I posted above and touched the usb ports on the rpi4 and snap!

The pi would not power up. I ordered replacements of the board and the power adapter. I plugged in the new board to the old power adapter and no joy. I plugged the new board into a new power adapter and it works. I have not tried a new power adapter with the old board yet . . . I am afraid it will toast a new power adapter with a short on the board.

What do you think?????

Code:

bash: halcompile: command not found

What do I need to do with this install to make halcompile work? I tried to run

Code:

sudo make setuid

while in the emc drectory where the source was downloaded but that does not work either. It returns

Code:

make: *** No rule to make target 'setuid'. Stop.

Any ideas?

No ideas on this one. I need halcompile to work for the project that I am working on.

Ok, Figured this one out.

To get halcompile to work you need to install linuxcnc-uspace-dev.

This is compile and put in a .deb file when you perform the steps in the installation.

For me to install this I had to go to the main user directory ~ in my case /home/pi/

I had to install a dependency

Then i could dpkg the linuxcnc-uspace-dev .deb file

Now halcompile works and I am happy again!

I appear to have managed to install Raspbian RT, and I am now at the stage where I am installing LinuxCNC, where I am to edit out the two lines of dependencies in the debian/control.bottom.in file. However, the instructions don't quite match what I am seeing in the file:

as opposed to just:

I am a complete novice, so I am not sure whether to remove the whole line, or just a portion.

John, a big thank you for putting these steps together.

Thanks,

Hi,
I followed the instructions on gnipsel.com/linuxcnc/uspace/ and everything went smoothly. However, when I tried to run pnccnf and got to the stage of test/tune I get the message that LinuxCNC is running in simulator mode and therefore cannot test hardware. From my google search I came to the conclusion that there is a seperate install for real time LinuxCNC. Do you know what might be going on or how I can install the linuxCNC real time version?

Hi Andy, This link seems to be blank. I would like to get the SD card image. Please advise how?

Thank you.
