[Dev-C++] Problem getting wxWindows-app to compile

[Jonatan <jon...@ho...>]

Hello!

I'm currently looking into the wxWindows-framework.
Using the latest 4.9.7.0 IDE, I get 394 errors upon compiling a very simple=
 program.
This is how my simple program looks like (taken from a tutorial at http://w=
ww.codelearn.com/cpp/icpp_wx1.html):

main.cpp:
---------
#include <wx/wx.h>
#include "basic.h"

IMPLEMENT_APP(BasicApplication)

bool BasicApplication::OnInit()
{
  BasicFrame
   *frame =3D new BasicFrame("Basic", 50, 50, 450, 300);

  frame->Show(TRUE);
  SetTopWindow(frame);
  return TRUE;=09
}

BasicFrame::BasicFrame
             (const wxChar *title,
                    int xpos, int ypos,
                    int width, int height)
             : wxFrame
                ( (wxFrame *) NULL,
                   -1,
                   title,
                   wxPoint(xpos, ypos),
                   wxSize(width, height)
                )
{

}

BasicFrame::~BasicFrame()
{

}

basic.h
-------
#ifndef BASIC_H
#define BASIC_H

class BasicApplication : public wxApp
{
  public:
=09virtual bool OnInit();
};

class BasicFrame : public wxFrame
{
  public:
=09BasicFrame( const wxChar *title, 
                int xpos, int ypos, 
                int width, int height);
=09~BasicFrame();

};
#endif

This program is pretty straightforward.
I've added the include paths, so the wx-headers are found. My first error i=
s

*** 320 C:\DEV-CPP\include\wx\defs.h
redeclaration of C++ built-in type `bool'***

I also get errors like:

*** 6 C:\DEV-CPP\include\wx\wxchar.h:429
#error "Please define string case-insensitive compare for your OS/compiler"=
 ***

and 

*** 99 C:\DEV-CPP\include\wx\font.h
virtual outside class declaration ***

Is there some option(s) I should activate/deactivate in Dev-C++ that I've m=
issed? Should I reinstall wxWindows or does it not work with 4.9.7.0?

Hopefully you've had the same problems and there is some silly thing I've m=
issed...

TIA

You must define __GNUWIN32__ (two underscores each), perhaps UNICODE or 
_UNICODE, depending on you are using it or not. The best for compile 
wxwindows was saidtwo months ago, make a makefile with
 CFLAGS=
 INC=
LIB= 
TARGET=
OBJS=

$(TARGET) : $(OBJS)
!include makeprog.g95.

I started going through the codelearn tutorial tonight (might as well see
which API is the easiest to use, yeah?) and I came up with three errors; two
of them are this type (in wx\wxchar.h and wx\string.h). The other is an
"Unsupported toolkit" in wx\fontutil.h.

I'm using 4.9.6.0, so the difference in version may be the thing; note the
mention on the download page for 4.9.7.0:
"/!\ WARNING /!\ : Due to changes in the C++ ABI in GCC 3.2, currently
available Dev-C++ Packages for the C++ language will not work."
Don't know whether that applies to wxWindows, but it's possible. (It's the
reason I haven't gone to 4.9.7.0.)

So anyway-- anyone encountered these case-insensitive compare and
unsupported toolkit errors in wx? Got any ideas on how to fix them?

Thanks,
R
