Porting C++ code from Windows to the Mac

Question

Howdy Ya'll,

I'm a long time Windows developer, and it looks like I'm going to be involved in porting a Windows app to the Mac.

We've decided to use Flex/Air for the gui for both sides, which looks really slick BTW.

My Windows application has a C++ DLL that controls network adapters (wired and wireless). This is written using the standard library and Boost, so most of it should work cross platform.

On the Mac, what IDE/complier do most folks use if they want to write C++? Also, can someone provide a pointer to whatever APIs the Mac has that can control WiFi adapters (associate, scan, disconnect, etc)?

Answer 1

The de-facto OS X IDE and compiler is xCode. It comes with every Mac, you just install it from the OS X install CD.

http://developer.apple.com/mac/ is the place to get more information on OS X APIs

Answer 2

xCode and a custom GCC I believe...

Answer 3

XCode is used a lot, as far as I know the combination editor (e.g. Textmate), command line gcc is in fairly heavy use too. (that's what I do on OS X)

For all API needs head to http://developer.apple.com e.g. the networking API's

Answer 4

xcode is the hotness, as people have already pointed out.

Having maintained a windows/mac codebase in the past, take a look at MVC:

So long as you keep the background logic distinct from the UI and from the platform-specific stuff (like file handling, networks, drawing to the screen, etc). That way, when you want to go to Linux in the future, you just have to write those platform specific components.

As for mac networking, are you on the level of connecting and so forth? Why not just let the OS handle that, and then you just see what connections are available? Why bother with whether or not the connection is wired or wireless? Because the OS has a lot of those tools already built in and users are used to making sure that the connection is there to do work, it seems odd to have an extra program to want to manipulate the network.

Answer 5

Xcode is the IDE for Mac OS X, you can download the latest version by joining the Apple Developer Connection with a free Online membership.

I don't believe there are any supported APIs for controlling wireless networking adaptors. The closest thing would be the System Configuration framework, but I don't know if it will let you do everything you want.

Also, I would strongly recommend against trying to use Flex/Air for your application's user experience. It may look slick to you on Windows as a Windows developer, but when it comes to providing a full Macintosh user experience such technologies aren't always a great choice.

For one example, I think Air applications don't support the full range of Mac OS X text editing keystrokes. While not all Mac users will use all keystrokes, for those people used to them trying to type in a text field that doesn't handle (say) control-A and control-E to go to the beginning and end of field is like swimming through syrup.

For a new application that needs to be cross-platform, I'd strongly consider building the core logic in C++ while using Cocoa on the Mac and WPF on Windows to get the best user experience on each platform. Both Mac OS X and Windows have modern native user experience technologies that their respective users are getting used to, and also have good ways for C++ code to interoperate with these technologies.

Answer 6

by the way for the uninformed, it's "Xcode" not "xCode". Sorry for being pedantic :/
