In my previous post I commented about the Cando device that I bought from Aliexpress.
Although it is described as a Cando, it is not related to the commercial CAN Analyzer CANdo, maybe the Chinese vendor did it to confuse the user. In fact it is a clone of the CANable device.
The CANable team created a nice interface to use the device, it is called “cangaroo”:
https://canable.io/getting-started.html#cangaroo
They have an executable program for Windows, but don’t have a pre-compiled version for Linux.
Here I’ll describe the steps to do it:
$ git clone https://github.com/normaldotcom/cangaroo
$ sudo apt-get install build-essential git qt5-qmake qtbase5-dev libnl-3-dev libnl-route-3-dev
$ sudo apt install libqt5charts5-dev
$ cd cangaroo
$ qmake -qt=qt5
$ make
Probably it will fail if you care using a recent Linux kernel:

It is easy to fix, open the file SocketCanInterface.cpp :
$ vi src/driver/SocketCanDriver/SocketCanInterface.cpp
And add this header line:
#include <linux/sockios.h>
Then execute make again:
$ make
And you run the application this way:
$ ./bin/cangaroo
You can also copy it to /usr/local/bin to be able to call it from anyware:
$ sudo cp ./bin/cangaroo /usr/local/bin/
