When I build a library file, use it in my project: Undefined symbols for architecture arm64

[mindstormygit]

Undefined symbols for architecture arm64:
"CInkData::GetRecoStrokes(int, int*, bool, bool)", referenced from:
CRecognizerWrapper::RecognizeInkData(CInkData*, int, int, bool, bool, bool, bool) in libWritePadReco.a77
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Changing BOOL to bool in GetRecoStrokes can solve this problem. I don’t know if there are any issues with this approach.
