Programming Forums - wxWidgets problem

Hey guys!

Mmm, i just installed wxWidgets 2.8.4 - it's the first time i've used it... im running Fedora 4.

I installed it using:

COMPILING USING CONFIGURE

=========================



* The simplest case

-------------------



If you compile wxWidgets on Linux for the first time and don't like to read 

install instructions just do (in the base dir):



> ./configure --with-x11

> make

> su <type root password>

> make install

> ldconfig

> exit

all went fine - but when i tried to create this app from this tutorial:

http://www.bzzt.net/~wxwidgets/icpp_wx1.html

it didnt compile - however i could compile the samples included with the wxWidgets package just fine...

i get this error:

...

obviously its not linking - i've set the $LD_LIBRARY_PATH to include /usr/local/lib which is where wxWidgets libraries are located...

i added -I/usr/local/include/wx-2.8/ to get the includes - but then gave more errors on linking.

i didnt play around with the $LIBS variable in the Makefile (i.e. -L/usr/local/lib/) because im not very familiar with linking... the flags are very foreign to me, its actually a little scary!

here is the full code:

// basic.h

#ifndef BASIC_H

#define BASIC_H



class BasicApplication : public WxApp {

        public:

                virtual bool OnInit();

};



class BasicFrame : public wxFrame {

        public:

                BasicFrame(const wxChar *title,int xpos,int ypos,int width,int height);

                ~BasicFrame();

};



#endif

// basic.cpp

#include <wx/wx.h>

#include "basic.h"



IMPLEMENT_APP(BasicApplication);



bool BasicApplication::OnInit() {

        BasicFrame *frame = new BasicFrame("basic",50,50,450,300);



        frame->Show(TRUE);

        SetTopWindow(frame);



        return TRUE:

}



BasicFrame::BasicFrame(const wxChar *title,int xpos,int ypos,int width,int height)

                        : wxFrame((wxFrame *)NULL,-1,title,wxPoint(xpos,ypos),wxSize(width,height)) {}

i hope someone can help! any response will be much appreciated! :D
