Mysensors Build Problem on Ubuntu 20.04 (RPi or Tinker Board)

[sghazagh]

Hi all,
I have problem compiling Mysensors library on Ubuntu 20.04 image running on RPi 3/4 or Tinker Board.

Getting the error like:

...
e/Linux/drivers/core -c hal/architecture/Linux/drivers/core/Print.cpp -o build/hal/architecture/Linux/drivers/core/Print.o
g++ -MT build/hal/architecture/Linux/drivers/core/interrupt.o -MMD -MP -DMY_RADIO_RF24 -DMY_GATEWAY_SERIAL -DMY_DEBUG -DLINUX_SPI_SPIDEV -DMY_LINUX_SERIAL_PORT=\"/dev/ttyUSB01\" -DMY_LINUX_SERIAL_IS_PTY  -Ofast -g -Wall -Wextra -std=c++11 -I. -I./core -I./hal/architecture/Linux/drivers/core -c hal/architecture/Linux/drivers/core/interrupt.cpp -o build/hal/architecture/Linux/drivers/core/interrupt.o

      |          ^~~~~~~~~~~
compilation terminated.
make: *** [Makefile:99: build/hal/architecture/Linux/drivers/core/interrupt.o] Error 1

It seems that its missing the <stropts.h> header, but have you any idea how I can resolve that?

Many thanks

P.S: I tried on both RPI3 and 4 also on Tinker board and the problem are same for all of them running Ubuntu 20.04.

@sghazagh Hi all,
I tried to create a empty file and it seems that it does work and does not make any problem for the Radio functionality!

Any idea what this header is and how can I find this genuine library header for future use?

touch /usr/include/stropts.h

@sghazagh When seraching for this file on google, I come across this hit: https://stackoverflow.com/questions/61029226/how-do-i-install-libraries-for-stropts-h
It states stropts.h is deprecated, and apparently the gateway doesn't use it, only includes it.
Could you file a bug report here to remove this include please?
