Are you sure your host and target have same version of QNX ?

My target have demons of MP3 ,there is a same problem when I run that application.
“unkown symbol:_unlockfilelock”
Is there a different authorizantion between the host and target when I create my network?

It have nothing to do with “authorizantion”. More likely, you are compile on a later (newer) version of QNX, where there is a _unlockfilelock() in library; but running on an earlier (older) version of QNX, where there is no _unlockfilelock(0 in library.

You can try to link your program "static"ly, (qcc command line option “-Bstatic”) to try to work arround the problem.
