[Question] Is it safe to call loggers factories during static initialization?

[Adnn]

We would like to initialize loggers implicitly (basically, one for each of our internal libraries, so we get one distinct "channel" for each lib).

Is it safe to call factories such as spdlog::stdout_color_mt() during static initialization? Or would it be subject to problems (such as static init order fiasco)?

There is no problem with generation by static variables.
However, you may encounter problems when calling the logger in destructor.
See #1738 and #2113

And on Windows, spdlog::shutdown() must be called before the application exits (at the end of main()).
If you do not call it, the logger flush operation will not be performed and the writing of log messages from memory to file may not be completed.

There are issues related to object lifecycle.
See #2113

The following are Windows-specific issues.

• Initialising spdlog inside DLL rather than main function #1530
• Is there a way to cleanly use spdlog after main() (i.e. in static / global objects' destructors)? #1738
