Re: [Question #234832]: compilation error

 

Question #234832 on rohc changed:
https://answers.launchpad.net/rohc/+question/234832

manish shivare gave more information on the question:
and i also try the syntax which is given on
http://rohc-lib.org/wiki/doku.php?id=library-first-application.
log is -
