Undefined symbol: std::__1::__libcpp_deallocate[abi:ne180100](void*, unsigned long, unsigned long)
Linker command failed with exit code 1 (use -v to see invocation)
Environment:
Xcode: 16.2
macOS: 15.x
React Native project
Using C++20
Deployment target: iOS 16.0
Using CocoaPods
The error happens during the linking phase, not compilation.
The project includes a native module that uses C++ (libc++), and I suspect it may be related to:
C++ standard mismatch
libc++ ABI mismatch
Deployment target inconsistency across pods
Xcode 16 toolchain changes
I have already:
Cleaned DerivedData
Removed and reinstalled Pods
Verified iOS deployment target is set to 16.0
Ensured CLANG_CXX_LANGUAGE_STANDARD is set to c++20
Still getting the same undefined symbol error.
Has anyone faced this with Xcode 16?
What could cause std::__1::__libcpp_deallocate[abi:ne180100] to fail during linking?
