syntax of wxLegendWindow::wxLegendWindow

Question

Hello
I am having an issue with syntax.
I have:

wxLegendWindow::wxLegendWindow( wxWindow *parent) : wxWindow(parent, -1, wxDefaultPosition, wxSize(LEGEND_WIDTH,LEGEND_HEIGHT)) m_WinParent(parent)

and when I compile I get:

C:\codeblocks-10.05-release\src\plugins\contrib\wxSmithContribItems\wxchart\wxchart-1.0\src\legendwindow.cpp|50|error: expected '{' before 'm_WinParent'|

The code I originally started with was:

wxLegendWindow::wxLegendWindow(
	 wxWindow *parent
):  wxWindow(parent, -1, wxDefaultPosition, 
			 wxSize(LEGEND_WIDTH, LEGEND_HEIGHT)/*, wxSIMPLE_BORDER*/),
	m_WinParent(parent)

However this raises the error:

C:\codeblocks-10.05-release\src\plugins\contrib\wxSmithContribItems\wxchart\wxchart-1.0\src\legendwindow.cpp|54|undefined reference to `_imp___ZN8wxLegendC1Ev'

I am not sure if this is "just" a syntax issue or a missing library.

My Build log follows:

My guess is the problem is the :

wxLegendWindow::wxLegendWindow( wxWindow *parent) ; // <<<< replace the colon
wxWindow(parent, -1, wxDefaultPosition, wxSize(LEGEND_WIDTH,LEGEND_HEIGHT)) m_WinParent(parent);

Another possibility is that there are too many )

wxLegendWindow::wxLegendWindow( wxWindow *parent, 
wxWindow(parent, -1, wxDefaultPosition, wxSize(LEGEND_WIDTH,LEGEND_HEIGHT), m_WinParent(parent));

The correct code you want is here. You probably made a mistake copying the code. Or you did not include the correct header files #include <wx/wxprec.h>

Thanks for the answer.
Neither of the proposed changes made it work though.
In case 1 the error are:

C:\codeblocks-10.05-release\src\plugins\contrib\wxSmithContribItems\wxchart\wxchart-1.0\include\wx\legendwindow.h|40|warning: attribute ignored in declaration of 'class wxLegendWindow'|

The second case gives me:

Sorry for the delay, <wx/wxprec.h> is included and the code for both files is identical. I believe the issue is with the linked libraries, as in I don't have them correct. Hopefully I will get a chance to work on it more this week.

Thank you.

The errors you posted have nothing to do with the libraries because the compiler has not gotten that far yet.
