I tried it on Windows today using the latest DMD installer, all default logger and settings.

I get: safe function [...].logImplf cannot call system function 'std.format.formattedWrite!(MsgRange, char, Result!()).formattedWrite'

How do I make formatted logging work?

Would be easier to diagnose your problem if you pasted your code and uncut complaint from the compiler.

Anyway, the following works, so it may give you a hint:

$ cat log.d
import std.experimental.logger;

void main()
{
	logf("just log %s and %d", "this", 1337);
}
$ dmd log.d
$ ./log
2015-10-01T11:23:57.291:log.d:main:5 just log this and 1337

Ah, I tried to format a custom struct that has a non-pure toString, because std.conv.to isn't pure either, sigh :(
