  • qt_plugin_instance: identifier not found 解决办法

    configure -debug-and-release -platform win32-msvc2008 -static -no-qt3support -qt-libpng -qt-libjpeq -qt-libmng -qt-libtiff -qt-zlib -qt-sql-mysql -openssl-linked -l D:\OpenSSL\inc32 -L d:\OpenSSL\out32

    错误:

    abstractvideorenderer.cpp

    audiooutput.cpp

    backend.cpp

    ..\..\..\3rdparty\phonon\ds9\backend.cpp(69) : error C2227: left of '->m_directShowMutex' must point to class/struct/union/generic type

    ..\..\..\3rdparty\phonon\ds9\backend.cpp(69) : error C3861: 'qt_plugin_instance': identifier not found

    At the compilation with vs2008 amd64 with this configure:
    configure -release -static -sse -sse2 -no-exceptions -no-qt3support -no-opengl
    I have bug at the compilation on phonon:
    ..\..\..\3rdparty\phonon\ds9\backend.cpp(69) : error C2227: left of '->m_directShowMutex' must point to class/struct/union/generic type
    ..\..\..\3rdparty\phonon\ds9\backend.cpp(69) : error C3861: 'qt_plugin_instance': identifier not found

    将'qt_plugin_instance' 改为qt_plugin_instance_phonon_ds9即可
