'undefined symbol' means that the dynamic loader sees that some program needs a 'symbol' (variables, functions, etc) to work with a certain library, but the loaded can't find any reference to that symbol in the library. This can happen if you built software using one library but tried to run using a library with a different version. (There are numerous other reasons too, but I'll probably only confuse you.)

Yes, as you said the problem was with two differet version sources clubbed and compiled . so compilation get success but it issues runtime error 'undefined symbol'. now i downloaded complete source of single version and it is working fine.

thanq once again
