Ok zelda
I finaly figured how to properly configure linker in ZinjaI IDE...well i like it ...
it is fast and lightweigth ..so do you can compile this program :
Code: [Select]
#include <windows.h>
LRESULT CALLBACK windowProcedure( HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam);
//TCHAR text[] = _T"Hello world Window!";
//auto WinMessageToString(UINT msg) -> std::string;

pretty standard c/c++ code for opening a window with a base message map.

What it really shows is that underneath all the nice basic 'OpenWindow' commands is some knarly low level stuff going on. you need window classes, icons, message loops, callbacks, etc

yes it is small window C app it shows primitive GDI drawing
but instead primitive you can create sprites too.
