Same here, not sure why that's happening.

What is that _ZN5folly3f146detail15kEmptyTagVectorE symbol, @kmagiera any ideas?

[flimble]

Same here

[SudoPlz]

This may be fixing the issue but I can't test because alpha 4 is not released yet, and cloning the repo fails (because of https://github.com/software-mansion/react-native-reanimated/issues/984). Any idea when alpha 4 is coming out?

[KoboBunny]

I'm also having an issue with android after upgrading to React Native 0.63 but @SudoPlz your explanation for iOS was perfect and completely resolved my issue so thanks so much for posting the patch!

I tried following the diffs you posted here about android on your "This" link @SudoPlz but I'm still running into issues. What specifically did you change to get it to work?

Below is the error I'm getting now:

[KoboBunny]

@jakub-gonet do you know when alpha.4 will be released? It seems the tag is already created but it would be great to know when we can expect it!

[SudoPlz]

@KoboBunny apologies for confusing you, I never got it to work, I'm still waiting for one of the maintainers of this repo to post an answer.

I just noticed that my "This" link contained a new .aar file for 0.63.0 and since we're facing a linker issue (which is probably because some method is missing from within those aar files I thought maybe the maintainers are already working on it and already have a fix - that was just an assumption)

alpha 4 exists indeed but I have no idea when they'll release it, we're both on the same boat here and I wish we could get someone from software-mansion to shed some light.

[terrysahaidak]

alpha.4 has been released. also, it includes support for RN 0.63. could you test it and post back here?

[SudoPlz]

I'll test in a couple of minutes and let you know, thanks for the heads up @terrysahaidak

[SudoPlz]

Yaaaaaaay it looks like the issue is gone on alpha.4 thank you so much @terrysahaidak
I don't have much time to test right now, but if anything else comes up I'll ping you.

I appreciate it.

[aganjali]

alpha.4 has been released. also, it includes support for RN 0.63. could you test it and post back here?

everything is fine! i can close this issue thank you.

[reinismu]

Uhh I cloned master and wanted to run Example on my android, but I got the same error. Am I missing something or this error has come back?

[jakub-gonet]

@reinismu, which ndk version do you use?

ls $NDK_MODULE_PATH/ndk should help determine that.

I have 21.3.6528147 version and it builds just fine.

[reinismu]

I have the same version. Tho I didn't set up NDK_MODULE_PATH env variable. Will see if it helps.

Nop. Still crashes. I do have Google Pixel 3. Maybe it has to do something with it?

I see that lib was built

but for some reason it is not picked up :thinking:
