Could someone explain when to use the /requires/ statement in package.xdc?
Are they needed when building libs or only when building an executable?

You should use the 'requires' statement to indicate that your package ALWAYS requires the presence of some other package. In other words, a consumer of your package cannot use it without some other packages being present on the package path.

If another package is required only for your package to be built, you should use 'requires internal'.

Also it's worth pointing out that the requires statements are
unnecessary for any library build; every multi-package xdc build
proceeds in "phases" and the first phase ensures that headers are
created for all packages before proceeding to the next phase which
builds any object files.

The requires statements are also unnecessary for executables _if_ you
implement module$use() for the modules in your package; see
http://rtsc.eclipse.org/docs-tip/XDCscript_-_Module-Body.mod ule%24use.
