There's my dockerfile to run the peak adapter in a docker container running ubuntu 18.04. The error is "Makefile:129 *** Unable to automatically find the kernel headers. These are mandatory to build the pcan driver. Please set the KERNEL_LOCATION variable to the root directory of your own built kernel."

What should I do next?

Hello,

We do not use Docker and cannot support Docker environments,
however it seems like the installation of kernel-headers is commented out:

Code: Select all

#RUN apt-get install linux-headers -y

As the error-message clearly states, these are required to build the PCAN-Linux driver.

Try to have your docker container setup with kernel-headers installed and try again.

Please also note the requirements mentioned in the PCAN-Linux documentation, chapter "2.2 - System Requirements":

http://www.peak-system.com/fileadmin/me ... an_eng.pdf

Please report back to us if this has resolved your issue.

Best Regards

Getting the can messages over socketcan worked instead of pcan_usb using the docker container.

During device setup in the container this code was used:
self.ecu.connect(bustype='socketcan', channel='can0')
#self.ecu.connect(bustype='pcan', channel='PCAN_USBBUS1', bitrate=250000)

Running this script on the device before container deployment allowed the messages to be uploaded:
sudo modprobe peak-usb
sudo ip link set can0 up type can bitrate 250000
sudo ip link set up can0
