[Android] Project cannot be build with latest NDK

[futuun]

Last version of android ndk (18) removed gnustl which is used to build this package

[Tanatcu]

Any updates of this issue?

[futuun]

Yea, I was able to use NDK 18 with that fix: https://github.com/futuun/react-native-webgl/commit/1a6f84280c26f184e335a6cf6989eaf996c82021 yarn add https://github.com/futuun/react-native-webgl.git#ndk18-fix in case you want to give it a try.

On applying the above patch, the build is successful but the app crashes with the error:

    java.lang.UnsatisfiedLinkError: couldn't find DSO to load: librnwebgl.so caused by: dlopen failed: library "libc++_shared.so" not found

Any idea how to resolve this?

@Morphinity I'm getting the exact same error now.

@futuun is it still working fine for you?

[Morphinity]

@markidm worked for me by changing exclude "**/libc++_shared.so" to include "**/libc++_shared.so" in android/build.gradle f04bc00117f0916f4a1db033df5b4cfa574cae00

[moxxuk]

Wow, thanks @Morphinity! Spent 3 hours trying to figure this out last night with no luck. Your fix works a treat.

Hi @futuun,

I'm not sure if I'm missing something. I had react-native-community branch installed, then I executed the yarn fix you provided. It compiled but the app crashed at runtime (could not find libc++_shared.so). Shouldn't your fix had patched my ./node_modules/react-native-webgl/android/build.gradle? I've had to patch it myself (following @Morphinity's instructions).

The patch is working now, I'm just looking for instructions for my CI to start building again.

Thank you all

[futuun]

Hey,

I haven't used that in a while. I’ll try the fix you mentioned and add it to my pr but I don't think i will find time to look at it before Friday. In the meantime you could add post install command that will automatically apply path that is working for you. With sed it would look something like:

sed -i '' 's/include "\*\*\/libc++/exclude "**\/libc++/g' ./node_modules/react-native-webgl/android/build.gradle

@futuun 's changes worked for me - I'm on NDK 19.0.5xxxxxx, RN 0.57.1, webgl 0.8

[ducNgbk]

@adbl @futuun Hi, have you managed to make it work with RN0.58 or above on Android?

[adbl]

@ducNgbk nope 😕

See https://github.com/react-native-community/react-native-webgl/pull/83

[ducNgbk]

@adbl Do you know what did change between RN 0.57 and RN 0.58 that cause thing stops working? I did digging. Then I found some keywords: Javascriptcore and 64 bit support. But nothing helps yet. It always end with this kind of error Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x3ee4 in tid 7743 (mqt_js), pid 7706 (com.testthree)

[adbl]

I have no idea but yeah, those changes sounds like reasonable suspects...
