config.h:39 : first defined here
-
I am trying to build a Raspberry PI controller.
I am using:- Raspberry Pi 3B+
- Arch Linux
- RFM69HCW attached to the GPIO pins
I followed the instructions on https://www.mysensors.org/build/raspberry/, however i get an error when i run
make:/usr/bin/ld: build/examples_linux/mysgw.o:/home/oznerol/git/MySensors/./hal/architecture/Linux/drivers/core/config.h:39: multiple definition of `conf'; build/hal/architecture/Linux/drivers/core/config.o:/home/oznerol/git/MySensors/hal/architecture/Linux/drivers/core/config.h:39: first defined hereThe error talks about a struct called
conf, that gets defined in the mentioned files.
And idea what this error is and how i can fix it?The error happens both with actual config settigns as well as with a plain
./configure.
