iOS app just closed at loading texture. about gdx-basis-universal HOT 18 CLOSED

But from what I can see, one iOS game I built and deployed with this library works quite stable and without issues for the last 4 months.

It can only be in one case: You forgot to mention some library, framework or settings that is available and used on your machine, on which you built your Basisu library and which is not on mine.

As I have shown before - the simplest project I created crashes on my machine (both in the simulator and on the device) and works fine on yours, on the developer's machine where you built your Basisu library.

It can't be anything but missing some important component at building.

BTW, which exact macOS VM project should I try?

I already said what and how to do here:
#4 (comment)
the only things was changed by time is newest version of XCode, Android Studio and MobiVM plugin.

from gdx-basis-universal.

Amazing find! My god, it was all that simple!
I don't really know why it behaves that inconsistently. To my knowledge, IntelliJ Idea/Android Studio uses the same Gradle RoboVM plugin/Gradle tasks to assemble iOS builds. And to be honest, I don't think there's any reason for runtimeOnly configuration to be there instead of implementation. I only put it there because it looked to me like it's a lighter version of implementation and is sufficient for the native artifact dependency.

Anyways, I'll update the readme and replace those dependency keywords. And thanks a lot for digging on it!

from gdx-basis-universal.

Hi and thanks for the report!

That's strange, I can run the demo on a simulator with the latest 1.2.0 just fine. I can't test it on a real device though, but I guess if that would be the same problem as you described it would crash no matter where.

It would be good to see the whole log. Can you please make a very simple test, just like placing the basis texture loading at the very top of the application listener's create():

public class App extends ApplicationAdapter {
    @Override
    public void create() {
        Gdx.app.setLogLevel(Application.LOG_DEBUG);
        new Texture(new Ktx2TextureData(Gdx.files.internal("test_texture.ktx2")));
    }
}

And if it crashes, please post the whole log since the app start.

Also just in case, a dumb question, do you have the iOS natives dependency in your roboVM Gradle module?

runtimeOnly "com.crashinvaders.basisu:basisu-wrapper:$gdxBasisuVersion:natives-ios"

from gdx-basis-universal.

I can run the demo on a simulator with the latest 1.2.0 just fine.

Did you mean 1.0.2? I don't see 1.2.0 version.
Right now I tried to set version to 1.2.0 and got this error message:
Could not GET 'https://jitpack.io/com/crashinvaders/basisu/basisu-wrapper/1.2.0/basisu-wrapper-1.2.0.pom'. Received status code 401 from server: Unauthorized
So I think you just make a typo.

About the topic error. I think FirebaseCrashlytic catch a errors messages and that's why I see just the app exit.
Therefor, I created default simple, libGDX project by using official gdx-setup.jar. Tried to run it on simulator with default JPG texture - it works fine. After that, I added dependencies, convert a texture into .basisu format and try to run it again.
And now I received full stack of the crash:

Thanks for the project provided.

Very strange to say the least. I tried the project on my iOS simulator and it works fine.

By looking at your stack trace, UnsatisfiedLinkError means something is wrong with the native library. It probably is not loaded or is loaded, but the method signature doesn't match. Also, the missing of these two log lines in your log tells that the problem is with the initialization of Basis library and not with this particular texture.

[basisu_wrapper.cpp] INFO: Basis Universal 01.16
[basisu_wrapper.cpp] INFO: Initializing global basisu parser

At this point, I was only tested the library on my macOS virtual machine. Probably on the real hardware the natives behave differently. I'll try to do some more tests and try to reproduce the crash.

from gdx-basis-universal.

Hmmm, it's very strange.
I also test it on virtual macOS. :) But as I said before, I tried to upload game on real device by TestFlight and it also crashed. So it doesn't' work on real device also as on my virual os + ios simulator. :)
In my test game, I log after every line of code and see the next:

BasisuNativeLibLoader.loadIfNeeded();
FileHandle file = Gdx.files.internal("textures/checkered256.basis");
Gdx.app.log(TAG, "Reading Basis file: " + file.name());
ByteBuffer basisuData = BasisuGdxUtils.readFileIntoBuffer(file);
Gdx.app.log(TAG, "Reading Basis file: done");
boolean valid = BasisuWrapper.basisValidateHeader(basisuData); // <---- Here crash happened.
Gdx.app.log(TAG, "Data is " + (valid ? "valid" : "invalid"));

I.e. seems like some Basisu* functions works but BasisuWrapper.basisValidateHeader crash the app. As crash log says it: (Ljava/nio/Buffer;)

My macOS: 12.7.1 (Monterey)
My iOS Simulator test device: iPhone SE 3rd Gen with iOS 16.2
My MobiVM plugin for Android Studio is: 2.3.20 (the latest)

from gdx-basis-universal.

I.e. seems like some Basisu* functions works but BasisuWrapper.basisValidateHeader crash the app. As crash log says it: (Ljava/nio/Buffer;)

No, actually BasisuWrapper.basisValidateHeader(basisuData) is the first line where the real native Basis Universal kicks in. There are many things that happen during that first call, including the native library load if it wasn't loaded, subsequent native Basis Universal initialization, and only then manipulation with the image data.

As I mentioned before, from the log it's most likely that the native library failed to load, so it might be not related to Basis in general. Hard to tell more at this point, I need to reproduce the crash.

One thing you could try is to download the project and run the demo. See if it behaves the same way.

git clone https://github.com/crashinvaders/gdx-basis-universal
cd gdx-basis-universal
./gradlew demo:ios:launchIPhoneSimulator

from gdx-basis-universal.

including the native library load if it wasn't loaded

I called BasisuNativeLibLoader.loadIfNeeded(); before this line and it completes without errors.

Ok. I did what you said:

BUILD FAILED in 14s
Mac-Admin:gdx-basis-universal admin$ 

So, as you can see - it failed to build and run.

Maybe you can make snapshot version with extra debug info and log output in BasisuWrapper.basisValidateHeader() and I can try it on my side.

Just in case, maybe it matters I have installed XCode 14.2 (14C18)

from gdx-basis-universal.

Very strange to say the least. I tried the project on my iOS simulator and it works fine.
#4 (comment)

As I see, you used simulator with iOS 16.4.
I used simulator with iOS 16.2. I checked it in XCode and it's no available simulator higher that my 16.2 on my MacOS (12.7.1)

The same things on MacOS (13.2 Ventura). 16.2 is a highest available iOS Simulator for that XCode v14.2 (14C18), that available for that MacOS.

My real device, where I also got a crash is iPhone SE with iOS 15,8.

So, I think you just used some modern thing that have no backward compatibility at building basisu-wrapper.framework.
The simplest way: Try to download iOS Simulator 16.2 and run on it my basisu-test (from this issue). If it will works - you need a virtual machine with older MacOS (12.-13.) with older XCode to re-build your basisu-wrapper.framefork

from gdx-basis-universal.

Hi, I'm terribly sorry, totally missed your previous message.

The Gradle issues most likely happen because you don't have Android SDK installed. But just for the sake of desktop/iOS tests, you can simply comment out the demo Android module line in the settings.gradle file at the root of the project:

rootProject.name = 'gdx-basis-universal'

// include ':demo:android' <--- Like this.
include ':demo:core'
include ':demo:desktop'
include ':demo:ios'
include ':demo:web'
include ':demo'

include ':basisu-wrapper'
include ':basisu-gdx'
include ':basisu-gdx-gwt'

It also can be related to the Java version. Which one you installed on the macOS machine (java --version)? I remember I had issues on other projects with specific Gradle versions that refused to work with too old or too fresh Java (JDK <11 or >17). It's unlikely the case here, but worth checking.

And just in case here's a fat jar. (unzip it) It's heavy due to it contains natives for all the desktop targets, so it should run anywhere. Just like

java -jar gdx-basis-universal-demo-986302f.jar

So, I think you just used some modern thing that have no backward compatibility

Good point, probably, I should use some extra compiler flags for that. I'll test it on older simulators. If it crashes there, it's a clear indication of native incompatibility.

from gdx-basis-universal.

The Gradle issues most likely happen because you don't have Android SDK installed.

I have it. But anyway I tried to comment it and it's doesn't help.

It's heavy due to it contains natives for all the desktop targets, so it should run anywhere.

To what end? The problem is with the iOS version of basisu, not the desktop version.

I did the following:

• Took another virtual macOS.
• Upgraded it to the latest version of macOS (14.1.2 - Sonoma).
• Installed the latest version of XCode 15.0.1
• Installed the latest version of Android Studio (2023.1.1)
• Downloaded basisu-test.zip from this thread.
  https://github.com/crashinvaders/gdx-basis-universal/files/13485285/basisu-test.zip
• Opened the project in Android Studio.
• Changed the startup config to the latest version of iOS Simulator (iOS 17.0) on the iPhone 15 simulator.
• Run it.
• Got the same error message I described earlier.

So I don't understand how or why you can run it on your side without error.

As I said earlier, if you make some snapshot version of your library with the most detailed log of BasisuWrapper.basisValidateHeader function execution, then I can run it on my side and maybe that way we will understand the reason.

Or you have to get a new, clean virtual machine, do all the steps I described above and try to execute them in it.

from gdx-basis-universal.

Is there any chance that the bug will be fixed? Or the project is abandoned in the "as is" stage?

from gdx-basis-universal.

Hello!
Sorry, but I have too little time to work on this project ATM and haven't tested other macOS VMs yet. But from what I can see, one iOS game I built and deployed with this library works quite stable and without issues for the last 4 months.

I have plans to finalize the mipmap features and update to the latest libs for the project sometime this month. Will try to set up a new virtual macOS and see if I can catch the error. So please go ahead and share anything else related to the bug if that might help to reproduce it.

BTW, which exact macOS VM project should I try?

from gdx-basis-universal.

Hello again!
So I finally tried to make a clean install of macOS VM to test the library. So far, it works without issues. I made two clean installs of OSX-KVM Ventura on two different Linux (Pop!_OS) machines. I only follow the https://github.com/kholia/OSX-KVM README guide and install the necessary software using Homebrew.

Pop!_OS 22.04 LTS x86_64 (on Intel i7 based systems).
Ventura 13.6.6
Xcode 15.2

Here's a barebones project I tested on (I tested this repo's demo too) - https://github.com/metaphore/basisu-test

Here are the full steps:

1. Follow the OSX-KVM README to get the macOS Ventura spinning (I tried Sonoma, but the installation is stuck at the magic mouse waiting dialog).
2. Install Xcode along with the iOS dev support from AppStore.
3. Accept the agreement in order to use XCode command line tools (click XCode > Settings > Locations > Command Line Tools dropdown and accept the dialog).
4. Open Terminal and install Homebrew.

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

5. Using Homebrew install the necessary software (git, openjdk (v21))

brew install git openjdk

6. Simlink JDK to bin folder.

sudo ln -sfn /usr/local/opt/openjdk/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk

7. Clone the basisu-test repo.

git clone https://github.com/metaphore/basisu-test
cd basisu-test

8. Build and run an iOS simulator:

./gradlew ios:launchIPhoneSimulator

And that's it. Worked for both of my attempts.

Here's the app log:

Notice that:

1. You don't need to set up any manual profiles or certificates to be able to build and run for iOS simulators.
2. You don't need to have Android SDK installed to build the iOS module.
3. Some awkward log messages like Can't get Metal device. Metal Display won't be available. are OK and don't break the app.

Could you please try the test project and the exact steps I described?

from gdx-basis-universal.

I don't use Linux, so I did steps starting from 4 (Open Terminal and install Homebrew) on my VM on Windows.

And yes it's works without crash on Sonoma 14.1.2 with XCode 15.3

But on the same VM, the test project that I sent to you here #4 (comment) did not works and crushes with the same error as before.

As I say before - this is a default libGDX project what was builded by gdx-setup.jar application.
The only things I did: is add Basisu by your instructions and convert default .jpg image into .basis format. And I run it from Android Studio. I don't know why so happens, but it's crashes.

from gdx-basis-universal.

Tried to run my test gdx project (#4 (comment)) by using terminal, by using the same command as on your - and it's works!!!

After that tried to run it from Android Studio - and received the same crash.

I don't understand why the same project works from terminal and crushes from Android Studio.

from gdx-basis-universal.

I continue testing...

If i run my basisu-test from Terminal by ./gradlew ios:launchIPhoneSimulator it build in folder :
\basisu-test\ios\build\robovm.tmp

If I run it from Android Studio it build in folder :
\basisu-test\ios\robovm-build\tmp\iPhone 15 - 17.4\ios\x86_64-simulator

So we can compare generated files. If we compare config.xml file we can see (as I think) the main difference. Worked version (from Terminal) has gdx-basis-universal line.
The version that crashes - has no it.

I tried to put this line in robovm.xml file - but got error at building time.

As I understood, Android Studio uses MobiVM plugin to build iOS app.
That uses by terminal command - I don't know. But seems like this is a problem. gdx-basis-universal - did not linked in Android Studio. May be it have to be added by some other way.

I removed binary result files from folders because it's too big and I can't attach archive, all other files can show you what I said and you can test it on your side.
basisu-test 4.zip

from gdx-basis-universal.

Finally I found the reason and can run the demo without crash from Android Studio.

The reason is: runtimeOnly that described in your "Using the library" -> iOS module (RoboVM backend) section.
https://github.com/crashinvaders/gdx-basis-universal#ios-module-robovm-backend

I just replaced it by implementation and now it runs without crash!

Here the result with runtimeOnly (you can see it in dependencies section on screen)

Here the result with implementation
