Undefined References

Solved!
Really was a link problem...
- add the path /usr/realtime/lib/ to the ldconfig
- add the flags
-L/usr/realtime/lib -llxrt -lrtdm -lpthread to the

with the libraries:

/lib/liblxrt.so
./lib/librtdm.so

add -llxrt -lrtdm to your linking libs.

Try to add -llxrt in your LDFLAGS, so for example make LDFLAGS+=-llxrt
