[PATCH] Fix OS X app bundle

[historic_bruno]

The new build system with Premake4 creates an app bundle for GCC and Xcode. It's incomplete, only generating the binary, and won't run properly. It seems all the game data and libraries should be copied into the bundle using the ​appropriate structure, which would be a nice official distribution method for OS X. It doesn't seem practical for SVN users because they want the structure of the SVN, not an app bundle. So perhaps the default compile on OS X should be a plain binary, but using a new flag an app bundle gets generated (once we work out the technical details).

Also worth investigating is how Xcode3 manages to compile and run an incomplete bundle (it works for me).

• ​Bundle Programming Guide
• ​Info.plist
• #macdev on irc.freenode.net

The following will work for the standard engine and Atlas, based on r10867:

(1) Xcode project file + precompiled libraries (to be unzipped into build/), and
(2) Patch to fix a few spots in the source code as well as permit loading data from ~/Library/Application Support/0AD/data rather than inside the .app bundle

(2) ​http://members.iinet.net.au/~tjkidd/0ad/clean-build-mac-r10867.diff

Has been tested to compile with Xcode 3.2.6 and Xcode 4.2.1. These files should also resolve #1073.

Thank you for your work on that important problem. :) We really need to support building and deployment on the Mac much better.

I'll do the review and give feedback in the next few days if that's fine. From what I can tell now I see a few things you apparently didn't take into consideration, but I would like to have a closer look until I elaborate on this.

Please see the comments in that topic, especially regarding the patch and Xcode project. Have the libraries been tested on OS X 10.5-7, which seem to be the most commonly used versions now? Are they only 64-bit?

I wonder if we could build "universal" 32/64-bit binaries to support both architectures, I know Mac Ports can do this with the universal variant.

What are the chances of tweaking premake so it can generate a single Xcode4-compatible project? :)

I don't know if premake 4.4 beta3 (most current version) generates Xcode4 projects well or if it's more or less the same as the XCode3 projects with all the problems like multiple project-files etc... I'm also not sure if using it before the final 4.4 release is a good idea. Maybe I can make a few tests about that in the next days too, but I'll need help for testing because I don't have XCode4. It's not free anymore and I didn't want to buy it because I don't even own a "real" Mac ;)

I was able to do away with some of the changes within clean-build-mac-r10867.diff. Patch file has been reloaded at the same address for those who want the latest.

You have seen my thread in the forums about this topic. http://www.wildfiregames.com/forum/index.php?showtopic=15511

The main problem with your patch is that it uses a manually created XCode project. It's important for us to use premake or another viable alternative to create all the different project-files on the supported platforms to avoid having to change it manually when we e.g. add or remove files.

I'm taking this ticket now, because I already know premake and the build-system quite well, but I would appreciate you help once It's ready for testing or if I need help. :) I'll try to keep this ticket an the thread up-to-date.

BTW, I've been working on a script to automatically download and build the game's dependencies, in place of Mac Ports. See #1112.

(In [10946]) Fixes #947 by generating a plain executable instead of an app bundle for development-builds. The plan is to create a bundle later as a separate deployment-step after building. NVTT build is also changed because the installnames were not correct when doubleclickig the executable.
