Was unable to build on Cygwin. Please have patience newb to wxWidgets and Cygwin.

created build-debug directory and navigated to it.

$ ../configure --enable-debug

Causes lots of output can attach a file if desired. Near the end:

Cygwin Eclipse linker error undefined symbol `wxString::ConvertStr

Using Eclipse and the MinGW tool chain I get the error: undefined symbol `wxString::ConvertStr(char const*, unsigned long, wxMBConv const&)'

This is a really simple project which should just show a window.

Source code is:

/*

#ifndef MAIN_H_

#define MAIN_H_

  public:
Main();
~Main();

};
#endif /* MAIN_H_ */

/*

* Main.cpp
*
*  Created on: Apr 16, 2020
*      Author: jjacobs
*/

#include "Main.h"
Main::Main() : wxFrame(nullptr, wxID_ANY, "First WxWidgets App") {}
Main::~Main() {}

/*

#ifndef FIRSTAPP_H_

#define FIRSTAPP_H_

#include <wx/wx.h>

};

#include "FirstApp.h"

wxIMPLEMENT_APP(FirstApp);

FirstApp::~FirstApp() {}

bool FirstApp::OnInit() { return true; }

I seem to be missing a chapter. Any and all help greatly appreciated.

I solved this myself the trick was to use x86_64-w64-mingw32-g++.exe in the "GCC C++ Compiler Command:" and also in the "MinGW C++ Linker Command:" inside of C/C++ Build Settings in Eclipse.
