Pure GUI apps for Win/Linux/Mac in C++ with G++

Question

GUI apps for Win/Linux/Mac in C/C++

Please, i want know how to write a "pure" "native" "API-level" apps for Windows and Linux and Mac in C++.

I don't want one-code run-anywhere, but a native code for every OS

Solution For Windows

Just use Mingw/Win32 API, its very simple!, very clear, and that way i like programming under Windows!.

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

Solution For Linux

If i use for example wxWidgets-dev/GNU G++, my application can't run on other PC/Linux if there don't install wxWidgets ?! if else, how to include wxWidgets library in my EXE ?

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

Solution For Mac

Objective-C++/GNU G++ is the solution ? or Carbon/C++/GNU G++ ?

Answer 1

Mac

In the Mac case, you'll just want to fire up XCode and use Objective-C. Objective-C++ is mostly used to let you access existing C++ libraries from Objective-C.

Don't use Carbon, it's deprecated. It was only intended to make porting from Mac OS 9 easier.

Linux

This one is tough because there's really no guarantee of much of anything. You can be pretty sure that X Windows will be there, but there's a whole variety of libraries (Gnome, KDE, WxWidgets, FLTK, Motif, etc.) that may or may not be available.

In the old days, you could expect Athena widgets to be available, since they shipped with X Windows, but they look so crappy (somewhere between Mac OS 3 and Palm OS 1) that hardly anyone wants to use them any more.

So you pretty much have to pick a library/toolkit and use it, and expect your users to install it. Most distros make installation of dependencies really easy these days, so it's not as annoying as, say, installing wxWidgets on Windows.
