[Bug c++/20584] New: inline function used but never defined

[nerijus at users dot sourceforge dot net]

When compiling wxWidgets I get a warning:
../wxWindows/include/wx/stattext.h:24: warning: inline function 'virtual
wxStaticTextBase::~wxStaticTextBase()' used but never defined

The code is:
class WXDLLEXPORT wxStaticTextBase : public wxControl
{
public:
    wxStaticTextBase() { }

    // overriden base virtuals
    virtual bool AcceptsFocus() const { return false; }
    virtual bool HasTransparentBackground() { return true; }

private:
    DECLARE_NO_COPY_CLASS(wxStaticTextBase)
};

I asked wxWidgets developer and he said "The others could be less clear but this
one is clearly bogus: compiler complains about dtor which it should generate
itself. Please report this as a gcc bug".

I am using gcc 4 from Fedora devel.

gcc (GCC) 4.0.0 20050314 (Red Hat 4.0.0-0.34)

I don't think this is bogus, given the following code (since you did not give the preprocessed source I 
have to guess):
struct wxStaticTextBase
{
  wxStaticTextBase(){}
  virtual bool AcceptsFocus() const{return false;}
  inline virtual ~wxStaticTextBase();
};

See how ~wxStaticTextBase is declared as inline but not defined anywhere, so we get an error.

I mean warning.

Could read http://gcc.gnu.org/bugs.html and provide the preprocessed source as my guess shows that 
this warning is correct.
