Hi,
I am trying to cross compile xenomai user space application with this
command for Beagle Bone Black
arm-linux-gnueabihf-gcc -I/usr/xenomai/include -I/usr/xenomai -D_GNU_SOURCE
-D_REENTRANT -D__XENO__ -lnative -L/usr/xenomai/lib -L/usr/xenomai/
-lxenomai -lpthread -lrt -Xlinker -rpath -Xlinker /usr/xenomai/lib
1_trivial-periodic.c -o 1_trivial-periodic -lnative -lpthread -lxenomai
But I am facing linking error as follows
In file included from /usr/xenomai/include/nucleus/trace.h:53:0,

This __xn_drtsc is the one for the x86_64 architecture, not for the ARM
architecture. So, what you have in fact done is install xenomai on
your x86_64 host, and using that installation to compile arm code.
This can not work.
How to install Xenomai in cross-compiled environment is thoroughly
documented in Xenomai installation instructions.
