I'm going to write a cross-platform application on Windows and Mac.
I must use C++ to finish it.
However I have no experience in programming in Mac and I want to start by using Visual C++ to write the Windows version first. Then port it to Mac.
May I know is it easy to port?
and What can I do to make the port more easily?
Thanks a lot.
Use a cross-platform IDE like http://www.codeblocks.org/
Use a cross-platform GUI toolkit like http://www.wxwidgets.org/
Know what the standard language provides, and what is specific to your OS.
If you need to use OS features, then create wrapper functions / classes in your code which provide an interface. Encapsulating OS dependencies in a few places makes it much easier to port.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
You may want to check out Qt. Note that Qt4 is free if you are developing free software. For my typically small scale projects, I don't need to change even a single line when "porting" from one OS to the other (linux to windows in my case).
IMHO a very well designed and simple to use toolkit, which I would suggest using even if you are developing windows only apps.
