As per google's new announcement for mobile apps to Support 64 bit architecture to upload or update the App to Google Playstore, I started working on it by changing the native c++ SDK to support x86_64 bit architecture. I am getting an errors when using the 64bit compiler.
I am getting an ambiguous error when calling this code NeedWriteJson(int64_t int64Val) and apart from this i am getting another error with respect to the same scenario which i have mentioned below(Error 2)
I am using this compiler options for 32 bit compilation:
/usr/local/android-x86toolchain/bin/i686-linux-android-g++
Is there any compiler flags i have to add to support this changed? since i have to change in more number of places with respect to memory.

For 64 bit compilation:
/usr/local/android-ndk/toolchains/llvm/prebuilt/darwin-x86_64/bin/clang++.
Since we dont need to create a standalone toolchain its using clang++.
virtual bool NeedWriteJson(bool boolVal) = 0;
virtual bool NeedWriteJson(int32_t int32Val) = 0;
virtual bool NeedWriteJson(int64_t int64Val) = 0;
virtual bool NeedWriteJson(std::string strVal) = 0;
virtual bool NeedWriteJson(double strVal) = 0;
Error1: error: call to member function 'NeedWriteJson' is ambiguous return toJsonController->NeedWriteJson(llongVal);
