    • 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 here

      The 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.
      Full compile log:

      [oznerol@goofball MySensors]$ make

    • RE: Is MySensors RPI GW 32bit only?

      Anyone tried this with RFM69HCW?

      I got it compiled on Arch Linux ARM with the aarch64 linux-rpi kernel after editing ./configure and hal/transport/RFM69/driver/new/RFM69_new.h as described above.

      [root@alarm git]# cat /proc/cpuinfo | grep Model && uname -a
Model           : Raspberry Pi 4 Model B Rev 1.4
Linux netberry 6.1.11-2-rpi-ARCH #1 SMP PREEMPT Tue Feb 14 06:34:59 MST 2023 aarch64 GNU/Linux

      It runs, but doesn't communicate with the radio properly:

Feb 16 13:20:45 DEBUG TSF:TDI:TSL
Feb 16 13:20:45 DEBUG RFM69:RSL

      I have built commit aa520cea, the latest from the development branch, using this config:
      ./configure --my-gateway=ethernet --my-transport=rfm69 --my-is-rfm69hw --my-rfm69-frequency=868 --extra-cxxflags="-DMY_DEBUG_VERBOSE_RFM69 -DMY_DEBUG_VERBOSE_RFM69_REGISTERS"

      My hardware should be fine, i didn't change anything and it was working with the 32-bit kernel before.

    • 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 here

      The 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.
      Full compile log:
