Hi! I tried to build pjsip for symbian (according to http://trac.pjsip.org/repos/wiki/Getting-Started/Symbian) Building pjproject for "Phone Debug (GCCE)" works, but if I build for "Emulator Debug (WINSCW)" I get several errors: Undefined symbol: '_get_libsrtp_errstr' pjproject-1.3 Undefined symbol: 'int res_GetXOFF(double, char) (?res_GetXOFF@@YAHND at Z)' Undefined symbol: 'int res_Resample(short const * const, short * const, double, unsigned short, char, char) (?res_Resample@@YAHQBFQAFNGDD at Z)' Undefined symbol: 'int res_SrcLinear(short const * const, short * const, double, unsigned short) (?res_SrcLinear@@YAHQBFQAFNG at Z)' I could not find any different configuration parameters depending on the target (GCCE or WINSCW). I use S60 3rd FP1 SDK. Any hints? thanks Klaus
