can not compile

[squidge]

We know the declarations exist otherwise you get a compile error instead. But do the definitions exist and are they identical? Also, is the file linked correctly, as wysota says?

well this is an extract from my .pro file

SOURCES += main.cpp\
mainwindow.cpp \
webdatacontroller.cpp

HEADERS += mainwindow.h \
webdatacontroller.h

and yeah they are indentical (think so. im 99,9% sure but i will check tomorrow because in germany its about 0:00 and my parents want to sleep)
so i will give you a sencored version of my sourcecode tomorrow

so i think did nothing wrong because my old version with nearly same code

EDIT:

well i checked my code in the old Qt creator version (1.3.1) and he gave the message that the reference problem is here:

QString specified_open_tag_regexpstr( this->constructDynamicOnlyOpenTagRegExp(tag, parameters, false) );
 
    QString open_tag_regexpstr( this->constructInvertedOpenTagRegExp(tag, parameters, false) );
 
    QString close_tag_regexpstr( this->constructCloseTagRegExp(tag) );

QString specified_open_tag_regexpstr( this->constructDynamicOnlyOpenTagRegExp(tag, parameters, false) );
    
    QString open_tag_regexpstr( this->constructInvertedOpenTagRegExp(tag, parameters, false) );
  
    QString close_tag_regexpstr( this->constructCloseTagRegExp(tag) );

To copy to clipboard, switch view to plain text mode 

the functions do exist i added them with QT creators auto function

i do not know what the problem is

all of my functions return a QString variable which i normaly could give to the constructor of a new QString or am i wrong?

Please show us the bodies of the three methods. You can strip out the contents if you don't want to show them.

i've got the problem and i'm such an idiot
the only thing i forgot was the classname infront of the functionname and the double :

my old problem...
i have started with vb.net and thus I often fall back in old patterns (because there you don't need this)

but thanks for all help
