[flext] unknown errors

[alessandro mason]

hi,
I'm trying to compiling this code:

"class PDFP : public flext_base{
FLEXT_HEADER_TS(PDFP,flext_base,setup)
QString filename;
float pages, pageNum;
  PDFP(){
    //define inlets
    AddInAnything("Require a PDF Document");
    AddInSymbol("PDF");// A symbol for pdf file name
    AddInInt(1);// Number of page to display
    //define outlets
    AddOutSymbol("Reading"); //A string name of image to display
    AddOutInt(1); // The number of pages of the document
  }

    void m_read(t_symbol* s){
         post("loading %s", GetString(s));
        std::string file=GetString(s);// conver the symbol to a string
        Poppler::Document*
document=Poppler::Document::load(QString::fromStdString(file));
            if (!document || document->isLocked()) {
                post("error while loading the document. Please check.");
                delete document;
                }
            pages=document->numPages();
            ToOutInt(1,pages);// send to outlet 1 the number of pages of the
loaded document
            // Access page of the PDF file
            Poppler::Page* pdfPage = document->page(pageNum);  // Document
starts at page 0
            if (pdfPage == 0) {
                post("error while reading the %i page", pageNum);
                }
            // Generate a QImage of the rendered page
        QImage image = pdfPage->renderToImage(72,72,-1,1,4,4);
            if( system("  mkdir .tmp" ))
            {
                system( "cd .tmp" );
            }else{
                post("internal error while creating a folder");
            }
        filename.fromStdString("page.PNG");

        image.save(filename,"PNG");//savepage
        const char* cstr = new char['p','a','g','e','.','P','N','G'];
        static const t_symbol *o= MakeSymbol(cstr);
        ToOutSymbol(0,o);
        delete pdfPage;
}

 void m_int(int i)
    {
            system( "page.PNG" );
            pageNum= i;// numer of pages of the document

    }
 static void setup(t_classid c)
  {
      //register methods
    FLEXT_CADDMETHOD(c,0,m_read);
    FLEXT_CADDMETHOD(c,0,m_int);
  }
FLEXT_CALLBACK_1(m_read,t_symbol*);  //callback wrappers
FLEXT_CALLBACK_I(m_int);
};
FLEXT_NEW("PDFP",PDFP) // set up PDFP"

and when I compile occours errors:

../../../flext/source/flmap.h|252|error: expected unqualified-id before ‘[’
token|
../../../flext/source/flmap.h||In constructor ‘TablePtrMap<K, T,
N>::TablePtrMap()’:|
../../../flext/source/flmap.h|202|error: expected primary-expression before
‘)’ token|
../../../flext/source/flmap.h||In constructor ‘TablePtrMap<K, T,
N>::TablePtrMap(TableAnyMap*)’:|
../../../flext/source/flmap.h|246|error: expected primary-expression before
‘)’ token|

that I don't know the meaning.
Can anyone help me pelase?

thanks
