Alpha iOS deployment available in SDK – please test

normen · January 21, 2013, 2:17am

So, I heard back from the avian developer and he found one bug in my build script and one in avain and now… It works!

From the next build on you will be able to install a plugin that allows you to deploy your applications to iOS in your nightly SDK install Of course, the audio and 3d renderers are still not implemented but the application runs in headless mode and you can try everything else but rendering

Heres the instructions (also available via F1 in the SDK ofc, it directly opens when the iOS properties panel is opened):

Note that the image loader already runs with native code, and beautifully so

Cheers,
Normen

This is great news! The sweet little iOS checkbox is one step closer =)

I’ve installed the plugin without any problems at all. Building the iOS project failed though. I have really no experience with iOS and XCode development so it’s hard for me to give you an explanation of what is wrong.

I got two questions when I opened the project (shown in screenshots).

I maybe missed a step somewhere because I just made a quick test…

normen · January 21, 2013, 12:31pm

Did you do the changes XCode suggests? Cause you shouldn’t for avian afaik (apart from that image, that doesn’t matter) Also what java version do you have installed? It might be it grabs the java from the system to do some linkage stuff… Or it fails to find its own JDK install… Anyway the native build for the binaries in the SDK looks good? Or is there warnings?

kwando · January 21, 2013, 1:33pm

Yeap, I happily did what Xcode suggested… and that did not turn out so good =P
I have both apples java 1.6 and oracles java 1.7 installed on my computer… they are both working but java 7 is the “default java”, I have to change this whenever I do a new project in the SDK (as you know lwjgl+os x+java 7 is not a very good combo in jME atm =P)

Anyway here is the build output from the SDK on a fresh BasicGame with iOS deployment enabled.

normen · January 21, 2013, 3:58pm

Looks good, did you try recreating the xcode project completely and not changing the compiler?

normen · January 21, 2013, 3:59pm

Oh wait… The ar command fails for some reason, guess I need to add quotes somewhere in the build script. This would explain why it doesn’t find root JVM native methods. Try changing the line that extracts the libavian.a in the ios-impl.xml

shirkit · January 21, 2013, 4:19pm

Too bad I don’t have a Mac to test this =\

normen · January 21, 2013, 6:09pm

@kwando: Yeah, seems like that was it, if you want to try before the next nightly, replace the -expand-ios-binary target in nbproject/ios-impl.xml with this:
[xml]

Expanding libavian.a for ${ios.arch}

[/xml]

kwando · January 21, 2013, 6:51pm

I tracked down that quoting before and the ar command succeeds with the quotes =) However Xcode is still not happy =/

What information is of use for you?

normen · January 21, 2013, 7:07pm

You get the same error in Xcode :? But it does extract the .a file now when you build in the SDK, right? My test setup has no spaces in the name, I guess I’ll have to test it in a deployed SDK build…

Edit: To explain whats happening in the background: The .o files of the project jars and native files have been built and normally the libavia.a would be extracted into separate .o files so the whole classpath and JDK shebang is accessibly to the linker. A list file generated by the build script is being created for that purpose too. Maybe that one didn’t get updated (as it checks for changes in the libavia.a I think). Did you clean and build the project so the library list gets created again?

normen · January 21, 2013, 9:41pm

Okay, tested at home and with a freshly enabled ios deployment option and the fix applied I can run the project on the iPad 6.0 sim directly…? Maybe try running the SDK on java 7? I didn’t quite get if you run on 1.6 or 1.7. Btw, you can just set the jdk folder read rights for “everyone” to “none” to avoid the SDk or other java apps using it, its easier than moving it. The SDK should work on Java7/OSX if you don’t have the heavyweight canvas enabled, but you cannot run applications atm, yeah

normen · January 22, 2013, 2:15pm

Did you have a chance to try it again @kwando? I can’t really reproduce the issue with the fix applied.

kwando · January 22, 2013, 2:36pm

Now it works! =D Xcode throws a lot of warnings though, but the build succeeds and iPad 6.0 sim starts!

I was running the SDK on 1.7, but after removing read access to that folder and starting the SDK on 1.6 it works.

Creating new BasicGame
Enable iOS deployment
Clean and Build
Open ios/project/jm3-ios.xcodeproj in Xcode
Hit the Run button
Watch the black iPad screen with a big smile knowing what is to come

The SDK works fine in java7 btw, I can use the scene explorer/editor and such things. Only issue is that new projects defaults to java7 and not java6 when running on java7.

EDIT: Actually the iPad screen is white…

normen · January 22, 2013, 2:56pm

Cool, thanks. Yeah the screen is white, thats fine. There is no UI elements yet, only when we have a working renderer we’ll need the gl context. You should be able to see your app do its thing in the log though. Test whatever you can test this way

The warnings in Xcode are mainly due to the fact that I import the i386 and arm binaries at the same time so that switching between device and emulator is easier, the wrong ones for that build will just be ignored.

Will windows user be able to deploy on android as well or like all engine it is mac only?
It will be a big + to j monkey if it is windows compatible

wezrule · February 8, 2013, 8:15pm

i think you meant iOS not android. And you need a mac + an appstore developer license (was $99/yr, last i checked) if you want to release something. And then an iphone/ipad/ipod to make sure it is actually working properly.

Or send normen $5 and he will distribute/test it for you

Yeah, as wezrule said, you can only deploy on mac anyway, theres not much we can do about this. Compiling the libraries should work on any platform but creating an actual iOS application and especially deploying it only works with apples hard- and software. This is so for any corss-platform dev tool (Unity, UDK etc) The content of this post is meant to be read as a straight information or question without an implicit dismissive stance or interest in having the other party feel offended unless theres emotes that hint otherwise or there's an increased use of exclamation marks and all-capital words.

Ok so i can’t create iOS game i wish Apple would have made Xcode cross platform

@mathieu.roux222 said: Ok so i can't create iOS game :P i wish Apple would have made Xcode cross platform

Yes you can, you just can't *deploy* it :) The content of this post is meant to be read as a straight information or question without an implicit dismissive stance or interest in having the other party feel offended unless theres emotes that hint otherwise or there's an increased use of exclamation marks and all-capital words.

zarch · February 8, 2013, 11:07pm

All you need is access to a mac for long enough to build and test.

Android on the other hand you can deploy to from a PC
