Edit Question
Title
Body
I have code where a global resource has to be set up by quite some code: globalClass foo; // global variable / object; give it a memory space to live void doSomething( void ) { foo.bar(); // use the global foo object } int main( int argc, const char *argv[] ) { foo( argc ); // foo can only be instantiated in main as it's using // information that's only available here doSomething(); // use the global foo object return 0; } As you can see, foo is of global scope - but to call its constructor I need some information that's only available inside of main . How can I achieve that? The only solution I could figure out is to make foo a pointer to globalClass - but that would result in a pointer dereferencing each time I'm using foo . This might create a performance problem when used in a tight loop... PS: In the real program main and doSomething would live in different files. And it's of course guaranteed that foo won't be accessed before it's instantiated.
