Possible to initialize static variable by calling function

Is this possible?

static bool initialize()
 {
   TRC_SCOPE_INIT(...); 
   ...
 }
 
 static bool initialized = initialize();
 

To make a very long story short, I need to call a series of macros (to initialize debugging messages) as early as possible (before thread X is started, and I don't have the ability to know when thread X is started).
