Has anyone tried porting to OS X?

[swillis11]

I was going to attempt to build/port to OS X if no one has done this yet. I'm not sure how ambitious this is though.

Running Mavericks

[Aloshi]

The only reason I haven't done it myself because I don't own a Mac.

I believe the only non-cross-platform thing is the VolumeControl singleton and in the master branch the InputManager hotplugging stuff. In theory, everything else should work.

(In the unstable branch, the platform-specific hotplugging code has been removed because SDL 2 supports it directly.)

ES is not targeted at OSX, it will eventually be ported in the far future. Try OpenEmu http://openemu.org/

Thinking about trying to put some cycles into this. While I love my RetroPie setup, would like to run it on a MacMini (dual-core 2.5Ghz) I've been thinking about as a decent HTPC platform.

On my first attempt:

macmini1:EmulationStation james$ cmake .

Do you have FreeType installed?

Throwing this pull request out there, in case it helps. The changes haven't been integrated with the new UTF-8 text rendering code though.

Hi, i managed to Configure and Generate Aloshi's master branch and generate a Solution in XCODE, however im stuck with the following error when compiling to dmg inside xCode:

In: ThemeData.h, on the line:
class ThemeException : public std::exception

Im getting: "exception specification of overriding function is more lax than base version"

I've looking around and seems to have something to do with the way the exception is thrown. Any help on this?

[Aloshi]

I'm guessing you need to add noexcept to the what() method and possibly constructor (just add noexcept at the end of the method signatures, see here).

[thiagobucca]

thx Aloshi, that worked. I'm struggling now with some "Expression Expected" errors but i think i can handle this. If anyone is interessed in trying this i can upload my xcode solution.

[jctwizard]

I would be very interested!

Just thrown a perfect OSX/Clang port here: #478
No visual glitches, only VolumeControl is missing.

[displaced]

I had worked on this too - see #473

I think pasnox's is more correct than mine, but I did add a bit of code that hides dotfiles from the directory scanner. My roms live on a network share which doesn't support HFS+ metadata, so OS X litters the directory with dotfiles containing that info.

[displaced]

I should probably add that I'm not particularly familiar with C++ so my code really was a case of 'hit it till it works'.

I had some luck getting cmake to generate an Xcode project. It'd be nice to get that into the project and get the build running so that it generates a neat .app bundle containing any referenced libraries which aren't present on OS X by default to help users just download and go.

[pasnox]

I guess it would be fine to be able to generate xcode project.
Creating a bundle is also possible for cmake, may add that later if needed.

Hi..
I am struggling with the same issue mentioned by "teknofile" commented on Dec 29, 2014.

Could someone help me to sort out the issue?
