I have been trying to run the
xddp-label.c example as given in the xenomai documentation on my raspberry pi model 3b+ with xenomai patched kernel. I can compile the program just fine, but when I try to run it I get the error:
socket: Address family not supported by protocol. I noticed I get the same error when trying to compile other xddp examples from the documentation. I suspect it has something to do with the
AF_RTIPC macro and the sockets, but I do not know anything about socket programming, so I am not sure. I hope someone can help me with this.
I am using a prebuilt xenomai kernel on my raspberry pi from this tutorial. I have tried running the program with a custom patched xenomai kernel as well, but without success.
For reference, the output of
Linux raspberrypi 4.9.80-v7-xeno3+ #2 SMP PREEMPT Fri Aug 10 15:04:48 KST 2018 armv7l GNU/Linux
The makefile I am using to compile the program:
SKIN=posix MAIN_SRC=xddp_label TARGET=xddp_label CC=g++ LM=-lm CFLAGS := -g $(shell xeno-config --posix --skin=$(SKIN) --cflags) LDFLAGS := -g $(LM) $(shell xeno-config --posix --skin=$(SKIN) --ldflags) #CC := $(shell xeno-config --cc) $(TARGET): $(MAIN_SRC).c $(CC) -o $@ $< $(CFLAGS) $(LDFLAGS)
I run the program with
sudo ./xddp_label.c. The OS is raspbian buster.
