Example Tacho Cross Compile Docker

[GetxCodexTogether]

I tried to run the sample program for the engines tacho.c with ev3dev-c.

Compiling and running the example on the Brick does not cause any problems.
But I don't want to write every line of code in the ssh terminal, I want to use an IDE.
So i tried Docker Cross Compile with eclipse.

When I use Docker-Cross Compile to compile the project and transfer it to the brick, the program gets stuck in the ev3_tacho_init while running on the EV3 and does not find the path "/sys/class/tacho-motor".

And one more question:
When I compile the example tacho.c with mingw on Windows and run it with tacho.exe, the brick is not found, although the IP address is set correctly. And there it gets stuck too.

I would be very happy about any support
