Is anyone familiar with MinGW and/or wxWidgets?

[Dodle]

I have a sample program "hello world" written in C++ & wxWidgets, but I am having trouble compiling it. My main problem is that for every header file that I want to include I have to type out the exact directory sting, e.g.:

#include "C:\DEV\wxWidgets-2.8.9\include\wx\wx.h"

This is the wx.h file:

#endif // _WX_WX_H_

To get the compiler to work I'll have to change each one of the include paths. I know there is a simpler way to do this, I just haven't figured it out yet. Do I need to have a wxWidgets environment variable?

[Dodle]

...Scratch that. Editing the wx.h file does no good.

A chap I knew was familiar with MinGe and wxDidgets

What is your development environment - Visual Studio? In there you can specify the source/include path (Tools | Options | tab Directories).

[Dodle]

I'm not using a development environment. I've wanted to learn how to manually code. I did try Dev-C++ and wxDev-C++, but I couldn't figure out how to compile this program with those either.

hworld.cpp:

/*
 * hworld.cpp
 * Hello world sample by Robert Roebling
 */

#include "wx/wx.h"

class MyApp: public wxApp
{
	virtual bool OnInit();
};

class MyFrame: public wxFrame
{
public:

	MyFrame(const wxString& title, const wxPoint& pos, const wxSize& size);

	void OnQuit(wxCommandEvent& event);
	void OnAbout(wxCommandEvent& event);

	DECLARE_EVENT_TABLE()
};

enum
{
	ID_Quit = 1,
	ID_About,
};

BEGIN_EVENT_TABLE(MyFrame, wxFrame)
	EVT_MENU(ID_Quit, MyFrame::OnQuit)
	EVT_MENU(ID_About, MyFrame::OnAbout)
END_EVENT_TABLE()

IMPLEMENT_APP(MyApp)

bool MyApp::OnInit()
{
	MyFrame *frame = new MyFrame( _T("Hello World"), wxPoint(50,50), wxSize(450,340) );
	frame->Show(TRUE);
	SetTopWindow(frame);
	return TRUE;
} 

MyFrame::MyFrame(const wxString& title, const wxPoint& pos, const wxSize& size)
: wxFrame((wxFrame *)NULL, -1, title, pos, size)
{
	wxMenu *menuFile = new wxMenu;

	menuFile->Append( ID_About, _T("&About...") );
	menuFile->AppendSeparator();
	menuFile->Append( ID_Quit, _T("E&xit") );

	wxMenuBar *menuBar = new wxMenuBar;
	menuBar->Append( menuFile, _T("&File") );

	SetMenuBar( menuBar );

	CreateStatusBar();
	SetStatusText( _T("Welcome to wxWindows!") );
}

void MyFrame::OnQuit(wxCommandEvent& WXUNUSED(event))
{
	Close(TRUE);
}

void MyFrame::OnAbout(wxCommandEvent& WXUNUSED(event))
{
	wxMessageBox(_T("This is a wxWindows Hello world sample"),
		_T("About Hello World"), wxOK | wxICON_INFORMATION, this);
}

I just need to MinGW compiler to know where to find the wx directory. I've tried setting an environment varialble:

WX=C:\DEV\wxWidgets-2.8.9\include

But that didn't do any good.

[ɹəuəllıʍ ʇɐb]

Sorry, I don't know MinGW. Doesn't it have any documentation on its website, e.g. Programmer's Guide?

[Dodle]

The documentation says that I need to put the header files in MinGW's search path (this is the simplest suggestion), which is the "include" folder in MinGW's directory. But I must be doing something wrong because it's not working.

I take C:\DEV\wxWidgets-2.8.9\include\wx and place it in C:\DEV\MinGW\include, but still no good.

[ɹəuəllıʍ ʇɐb]

That is exactly the point; how do you define the MinGW search path - an environment variable?

[Dodle]

That's what their website said: MinGW searches in the "include" folder.

[Dodle]

I think I'm going to give up and try Visual C++.

[ɹəuəllıʍ ʇɐb]

That seems like a sensible idea; no point of messing with something that nobody has ever heard of.

Do you have Visual Studio (or Visual C++) installed? If not, you know that there is a free version of Visual Studio, called Visual Studio Express ?
