Please post an excerpt of your code exposing this issue (the library
part, and the program part).

You should note that compiling libraries or programs for Xenomai usually
involves compilation flags obtained with xeno-config.

You should also note that "send()" is a glibc function, so calling a
function with the same name is a bad idea.
