The Makefile is for Xenomai applications and modules and works with
Linux 2.4 as well. That makes is somehow difficult to read. But the
compiler and linker flags for your application are:
CC=$(shell $(XENOCONFIG) --cc)
CFLAGS=$(shell $(XENOCONFIG) --xeno-cflags) $(MY_CFLAGS)
LDFLAGS=$(shell $(XENOCONFIG) --xeno-ldflags) $(MY_LDFLAGS) -lnative
LDFLAGS+=-Xlinker -rpath -Xlinker $(shell $(XENOCONFIG) --libdir)
This is for the native skin. For rtcansend you also need to add -lrtdm.

Are you cross compiling? Then the include path above is wrong. Please
tell use, what exactly you have typed to compile the program. Maybe just
DESTDIR is not set properly.
Wolfgang.
