classes DummyXXXAnalyzer have not a stub for virtual function endAnalysis().
I use strigi version 0.5.5 and have this version of header
streamsaxanalyzer.h

--------------
    virtual void startAnalysis(AnalysisResult*) = 0;
    /**
     * Is called when the analysis of a stream is finished. You can do
     * cleanups here, if necessary. Note: This is also called if, while
     * parsing the XML document, non-well-formedness is detected.
     */
    virtual void endAnalysis(bool complete) = 0;
    /**
     * This is called when an opening XML tag was detected. For documentation
--------------

and what I have in kio/kio/dummyanalyzers/dummyanalyzers.cpp

class STRIGI_PLUGIN_API DummySaxAnalyzer : public StreamSaxAnalyzer {
public:
    DummySaxAnalyzer() {}
    const char* name() const { return "DummySaxAnalyzer"; }
    void startAnalysis(AnalysisResult*) {}
    bool isReadyWithStream() { return true; }
    // there must be endAnalysis() stub
};

and this error is in DummyLineAnalyzer and in DummyEventAnalyzer
