Error compiling for RPI4 64 bit: RFM69_MAX_PACKET_LEN

[joaoabs]

Hi,

Trying to compile MySensors MQTT GW for RPI4 64 bits.
Overcame the initial error described here but now having a compiling error down the road.

make: *** [Makefile:99: build/examples_linux/mysgw.o] Error 1

My configure command is

./configure --my-gateway=mqtt --my-controller-ip-address=127.0.0.1 --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=MySensorsGW --my-transport=rfm69 --my-rfm69-cs-pin=24 --my-signing=software --my-signing-request-signatures --my-rfm69-frequency=433 --my-is-rfm69hw --soc=BCM2711

This error might be related wit the fact that I commented some flags in the configure file (I admit I blindly followed some instructions in an older post and I have no idea (neither knowledge) about what consequences may come from this). Maybe this error is related?

[Edit] Tried the same compilation in a RPI3 with 32bit OS and went fine, so I'm guessing this might be related with the fact I'm compiling for 64bit. Maybe MySensors isn't yet ready for 64bit?

Any suggestion?

Cheers,
Joaoabs

It won’t be until someone wants it badly enough, and has the time and skills to do whatever is needed.

You seem to have made some progress. Hopefully you or someone else can figure out how to proceed.
