Can One Process have two spdlog instance？

[kanli201904]

the problem is :The spdlog exception is like : " the thread pool is not exist"
the case is : We create one shared XXX.so , that use spdlog to record some logs, then one user use the XXX.so in his process. the user also use the spdlog to record logs. As the result: becaust the user also call the spdlog::init_thread_pool, that we destroy the spdlog's thread pool in the so. the spdlog can not be generated inner the so module

There is no support (#1448). But you can create thread-pool for each process.
See: https://github.com/gabime/spdlog/wiki/6.-Asynchronous-logging#spdlogs-thread-pool

@tt4g : thank you very much. if we can' t use the theadpool in the XXX.so( only use the spdlog::rotating_logger_mt(),), the urer process (which call the XXX.so) use the thread pool ,can the solve the problem ?

[tt4g]

I think the problem will no longer occur.
Because The spdlog::async_logger uses a thread pool, but not spdlog::rotating_logger_mt() (that returns spdlog::logger). Therefore, spdlog::init_thread_pool() should not be called in XXX.so.
