If your compiler does not support std::atomic<long long>, it means that the implementation of the C++ standard library on your compiler does not provide support for atomic operations on long long data type.
In such cases, you can try using alternative approaches to achieve atomicity, such as:
Use a different integral type: If your compiler supports atomic operations on other integral types like
intorint64_t, you can consider using them instead.Implement your own atomic operations: You can create a custom class or functions that provide atomic operations on
long longusing platform-specific synchronization primitives like mutexes or compare-and-swap instructions.Explore third-party libraries: There are some third-party libraries available that provide atomic operation support across various platforms and compilers. You can search for these libraries and see if they offer support for
std::atomic<long long>in your specific environment.
Remember to check the documentation and compatibility of any alternative approach you choose to ensure it meets your requirements and works well with your compiler.
