Logs from a native plugin not visible in Player's output_log

Unity Engine
1

Hello,

My c++ native plugin logs various debugging information. This info shows up in the editor log, but if I build the project and launch the player, the output_log file doesn’t contain any logs from the plugin.

I tried checking the ‘development build’ checkbox, in addition I set Full logging for all categories in the player settings, but that didn’t help. What am I missing?

How do you output the info from c++ side?

The usual C++ way:

std::cout << “foobar” << std::endl;

It won’t. Unity log is not connected to streams. It seems to be just editor redirecting plugins outputs to it’s console. Player and builds settings only related to unity Debug.Log* functions. If you want to see logs in console, use one of those methods. I’m not sure if it is possible directly from native plugin, but you may provide a callback for logging from unity side.

palex-nx, thanks. Do you think it is possible to redirect plugins outputs the same way Editor does it?

I mean, by writing some clever code in C#

May be this Process.GetCurrentProcess Method (System.Diagnostics) | Microsoft Learn and this Process.StandardError Property (System.Diagnostics) | Microsoft Learn will help. Or setup a named pipe for your log.

Thanks palex-nx, that looks promising
