Hello everybody,
I'm new to GUI programming and Ultimate++.
#include <CtrlLib/CtrlLib.h>
//#define _WIN32_WINNT 0x501
using namespace std;
using namespace Upp;
GUI_APP_MAIN {
PromptOK("Hello world");
}
I tried at first to compile the examples. Unfortunately I get errors in the example above:
D:\upp\uppsrc\Core\Socket.cpp: In function 'int Upp::sGetAddrInfo(const char*, const char*, addrinfo**)':
D:\upp\uppsrc\Core\Socket.cpp:44:47: error: 'getaddrinfo' was not declared in this scope
return getaddrinfo(host, port, &hints, result);
^
D:\upp\uppsrc\Core\Socket.cpp: In static member function 'static DWORD Upp::IpAddrInfo::Thread(void*)':
D:\upp\uppsrc\Core\Socket.cpp:65:24: error: 'freeaddrinfo' was not declared in this scope
freeaddrinfo(result);
I'm compiling with MinGW. What do I have to do?
Regards
Marco

After installing Visual Studio Express 2010 and Windows SDK:
Everything compiles properly, but still my questions about the platform independency remain:
Where is the advantage to use Ultimate++ when I have to use a Visual C++ compiler? Is my Code really platform independed?
Am I really forced to use the VC compiler?
I would be glad for a discussion about this topic!! Or is there already another one in the forum?
Good night!

Hi Yeti,
Don't worry, U++ is as platform independent as possible. There is many people using mingw. By the way, they say that it works much better with the TDM mingw. AFAIK mingw is not officially supported on windows, but it should work. Also, I think you can use Clang compiler on windows. Even the Open Watcom compiler should have some support in TheIDE.
But the real beauty of platform independence is that once you have a working U++ code on windows, you can simply compile it on Linux or BSD, or vice versa. There are even people who develop (and even compile  ) Windows applications on Linux 
Best regards,
Honza

I am setting up to convert multiple 13 year old healthcare VB6 apps to C++, and I'm determined to break away from Microsoft, the upgrade frenzy, and the .Net Framework overhead. So my updated apps will be running on Linux boxes, micro/nano ATX boards, small Windows free installs that we could make 1,000,000 of without being required to buy a windows license fee to be legal.
So the apps you develop on U++ can be built/compiled for/on Linux or Windows or OSX, either. So I send you a project folder and you choose which platform to build/compile, and deploy the app.
I believe our future is platform neutral, like Net Neutrality, able to run on any platform.
This is why I have fought so strongly to get a couple example projects debugged using MinGW while everyone is suggesting I get MS VS and my problems will be over.
My mission is to find a powerful(Non MS) C++ IDE w/GUI to marry and spend the rest of my life with...

. This is not necessary to add "using namespace std". Which version of UPP do you use ? what is your OS ?
