Global Instances

With the global instances method, all instances are placed within the current compilation unit. As a consequence, templates are reinstantiated during each recompilation; they are not saved to the template repository.

Template instances receive global linkage. These instances are visible and usable outside the current compilation unit. As a consequence, instantiation in more than one compilation unit results in multiple symbol definition errors during linking. The global instances method is therefore suitable only when you know that instances will not be repeated.

Specify global instances with the -instances=global option.

Global instances can be used only with the definitions-included template organization. The compiler does not search for definitions.
