Hi, Due to some reasons, I am unable to compile the project of MicroSIP.exe ( 3.01.5 ) version using pjsip libraries. I have downloaded all libraries of pjsip and compiled them. After linking these libraries to MicroSIP project following undefined references errors are occuring frequently.. microsipDlg.obj : error LNK2019: unresolved external symbol _pjsua_vid_codec_set_priority referenced in function __catch$?PJCreate at CmicrosipDlg@@QAEXXZ$0 1>microsipDlg.obj : error LNK2019: unresolved external symbol _pjsua_call_get_vid_stream_idx referenced in function "void __cdecl on_incoming_call(int,int,struct pjsip_rx_data *)" (?on_incoming_call@ @YAXHHPAUpjsip_rx_data@@@Z) 1>microsipDlg.obj : error LNK2019: unresolved external symbol _pjsua_vid_enum_devs referenced in function "public: void __thiscall CmicrosipDlg::PJAccountAdd(void)" (?PJAccountAdd at CmicrosipDlg@@QAEXXZ) 1>SettingsDlg.obj : error LNK2001: unresolved external symbol _pjsua_vid_enum_devs 1>SettingsDlg.obj : error LNK2019: unresolved external symbol _pjsua_vid_enum_codecs referenced in function "protected: virtual int __thiscall SettingsDlg::OnInitDialog(void)" (?OnInitDialog at SettingsDlg @@MAEHXZ) 1>D:\Dev-Licensing\MicroSIP-3.0.15-src\Debug\microsip.exe : fatal error LNK1120: 4 unresolved externals I have compiled PJSIP 2.0 beta with all dependencies and it worked fine for me..every project is being compiled succesfully and i linked the lib files also into the propject settings.
