Hello, I encountered six linker errors when compiling the latest codes of FSComm in VS2008. I followed the steps from here: http://wiki.freeswitch.org/wiki/FSComm#Windows. Someone else seemed to have the same issue but got no answers: http://article.gmane.org/gmane.comp.telephony.freeswitch.user/21757/match=fs... . Please enlighten me how to deal with these errors. Thanks and best regards, -Jingwei 10>fshost.obj : error LNK2019: unresolved external symbol "public: __thiscall Channel::Channel(class QString)" (??0Channel@@QAE@VQString@@@Z) referenced in function "private: void __thiscall FSHost::eventChannelCreate(class QSharedPointer<struct switch_event>,class QString)" (?eventChannelCreate@FSHost@@AAEXV?$QSharedPointer@Uswitch_event @@@@VQString@@@Z) 10>mainwindow.obj : error LNK2019: unresolved external symbol "public: __thiscall StateDebugDialog::StateDebugDialog(class QWidget *)" (??0StateDebugDialog@@QAE@PAVQWidget@@@Z) referenced in function "private: void __thiscall MainWindow::debugEventsTriggered(void)" (?debugEventsTriggered@MainWindow@@AAEXXZ) 10>mainwindow.obj : error LNK2019: unresolved external symbol "public: __thiscall ConsoleWindow::ConsoleWindow(class QWidget *)" (??0ConsoleWindow@ @QAE@PAVQWidget@@@Z) referenced in function "private: void __thiscall MainWindow::debugConsoleTriggered(void)" (?debugConsoleTriggered@MainWindow @@AAEXXZ) 10>prefdialog.obj : error LNK2019: unresolved external symbol "public: __thiscall CodecWidget::CodecWidget(class QWidget *)" (??0CodecWidget@ @QAE@PAVQWidget@@@Z) referenced in function "public: void __thiscall Ui_PrefDialog::setupUi(class QDialog *)" (?setupUi@Ui_PrefDialog @@QAEXPAVQDialog@@@Z) 10>prefsofia.obj : error LNK2019: unresolved external symbol "public: void __thiscall CodecWidget::setCodecString(class QString)" (?setCodecString@CodecWidget@@QAEXVQString@@@Z) referenced in function "public: void __thiscall PrefSofia::readConfig(void)" (?readConfig@PrefSofia @@QAEXXZ) 10>prefsofia.obj : error LNK2019: unresolved external symbol "public: class QString __thiscall CodecWidget::getCodecString(void)" (?getCodecString@CodecWidget@@QAE?AVQString@@XZ) referenced in function "public: void __thiscall PrefSofia::writeConfig(void)" (?writeConfig@PrefSofia@@QAEXXZ)
