7.4.5 Template Instance Automatic Consistency With -instances=extern

The template repository manager ensures that the states of the instances in the repository are consistent and up-to-date with your source files when you specify -instances=extern.

For example, if your source files are compiled with the– g option (debugging on), the files you need from the database are also compiled with– g.

In addition, the template repository tracks changes in your compilation. For example, if you have the— DDEBUG flag set to define the name DEBUG, the database tracks this. If you omit this flag on a subsequent compile, the compiler reinstantiates those templates on which this dependency is set.
