Here’s the part that fails. It needs to compile sources, but the platform you’re running it on has libraries missing needed for it, specifically one dealing with usb devices. If you’re on linux, try installing libusb-dev through your package manager and retry.
Thank you! As I said I am completely new to Linux and I think this leads to even more questions....
So I managed to install libusb-1.0 and retried. Now the error massege is the same. I think the path of this package I recently installed is not yet registered to the PATH variable.
So I asked google how to append the path of the corresponding .pc file to PKG_CONFIG_PATH. But that environmental variable does not exist on my system. So all attempts to add the path lead to nothing.
echo $PKG_CONFIG_PATH
--> no output
env
--> shows a lot of vars but nothing with PKG*
Do I have to define the var by myself? Is sth wrong with PKG-CONF?
ok, I think now I managed to install the package.
Thank you. After libusb-dev was installed another long error log appeared and I had to install another -dev package.
After that it installed the "co2-monitor" block set.
But there seems to be no end: now I am getting an error message in the debug sidebar from node-red.
it said:
"HID interface run on error: Error: cannot open device with vendor id 0x4d9 and product id 0xa052"
As the sensor I am trying to connect to the rapspi is an USB device I guess it has something to do with missing or wrong configuration?
lsusb shows that the device is at least there and with the above IDs. But I don't know if the right class is defined for the sensor. Does "HID interface" mean that he tries to deal with an input device (as a mouse or keyboard)? I assume that that would not be the correct behavior.
I would be pleased to get more help here. I am learning with every new error message...
