Hi all,

what is symbol lookup error? how can i solve this ?

I got this problem when i run my compiled source

# realplay /usr/local/songs/imuscut.lobster.ra

/opt/real/RealPlayer/realplay.bin: symbol lookup error: /opt/real/RealPlayer/plugins/rarender.so: undefined symbol: _ZN25CRealAudioRendererFactory23CreateRealAudioRendererEPP8IUnknown


Thanks

'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
