API-level Unicode GUI Native apps in C++ for Windows / Linux / Mac OS X.

I am looking for writing a simple Unicode, GUI, Native, application, that can be run without need any non-standard library, written in C++ compiled with GNU-GCC (g++).

NOT

I don't mean one-code-source run-anywhere, but 3 (Win/Linux/Mac) code source! run-without-library (native application).

• Native application

  Application can run without need any non-standard library, only the operating system C++ runtime (like MSVCRT on Windows).

• Unicode application

  Right-to-left Window Layout (to support Right to left reading languages), with two buttons [Message] to show UTF-8 strings ("اهلا بالعالم") in a message-box, and [Exit] to... I think exit! :p

The solution for Windows (Windows 7)

NOTE: This application is attached only with MSVCRT.DLL, that mean is a native windows C++ application.

The solution for Linux

Please HELP!

How to run the application on Linux without telling the user to install this and this.. a native Linux application!

• What is the file format must be? ELF, Bin...?
• X11 is the native Linux GUI library? or WxWidgets, QT, GTK+, gtkmm.. ???!!!
• Can be run on Gnome and KDE? or need a different code source?

Any one know the solution for Linux?

The solution for Mac OS X

Please HELP!

I think the solution for Mac OS X is Cocoa in C++ with G++! but I'm not sure!

• Can G++ build a native Mac OS application with Cocoa?

Or Qt. Not 'native' but neither is MFC, WPF, Silverlight ....

X11 has NO native GUI library. Learn wxWidgets and use it on all three platforms. It will handle the interface to Win32 and Quartz for you.

Windows API:

#undef  UNICODE
#define UNICODE
#include    <windows.h>

int main()
{
    MessageBox(
        0,
        L"اهلا بالعالم",
        L"Hello World in Arabic !",
        MB_ICONINFORMATION | MB_SETFOREGROUND
        );
}

Building with MinGW g++ (producing a.exe):

C:\test> g++ --version | find "++" g++
(TDM-2 mingw32) 4.4.1

C:\test> g++ -O -pedantic -std=c++98 -Wall -Wwrite-strings -Wno-long-long -mwindows x.cpp

C:\test> _

Building with Visual C++ (producing x.exe):

C:\test> (cl /nologo- 2>&1) | find "++"
Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 16.00.30319.01 for 80x86

C:\test> cl /nologo /EHsc /GR /Zc:forScope,wchar_t /W4 x.cpp /link user32.lib /subsystem:windows /entry:mainCRTStartup
x.cpp

C:\test> _

I think this is fairly "complete", but it's unclear what "complete" means.

Anyway, hth.
