I get: safe function [...].logImplf cannot call system function

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
