[3.16.1] [0.76.1] Implicit instantiation of undefined template 'std::basic_stringstream<char>'

[dawid-bytys]

Description

Hello,

I found a bug when building for iOS in Release mode (in Debug it works fine) on RN version 0.76.1 and reanimated version 3.16.1. The bug is related to the new architecture (and possibly XCode version 15.2?).

Steps to reproduce

1. npx @react-native-community/cli@latest init App
2. yarn add react-native-reanimated
3. cd ios && pod install
4. add plugin to the babel.config.js
5. try to build the app in XCode in Release mode (edit existing scheme and set Run to Release)

Having the same issue

[adrianperomingo]

Same versions as @dawid-bytys even Xcode 15.2 (15C500b). Just in Release mode

This is the file which throws the error: .../node_modules/react-native-reanimated/Common/cpp/reanimated/NativeModules/NativeReanimatedModule.cpp

Redirects to line 303 when clicks on the error

Please help 😞

fixed by adding new import on top (or any place in the header section that you are sure it will load) of this file node_modules/react-native-reanimated/Common/cpp/reanimated/NativeModules/NativeReanimatedModule.cpp:

#include <sstream>

I am curious why it was fine in version in 0.75 but broken in 0.76.1....(both XCode 15.1)

Can someone add it to a commit and make a release for the hotfix? It's a very simple fix...

You can use patch-package for now.

[adrianperomingo]

can patch-package works in an CI/CD using AppCenter? @dawid-bytys

Short Answer: I am not an expert of C++ and this library. Not sure will that cause duplicate header import in other React Native/XCode combination then break their building process...better use patch-package or yarn patch for now

Yes, just add "postinstall": "patch-package" script to package.json.

Yes, i have already did it and works in local. I wanted to know about in AppCenter. It's fine guys, thanks for the help ❤️
