5. A program that contains no derivative of any portion of the Library, but is designed to work
with the Library by being compiled or linked with it, is called a "work that uses the Library".
Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the
scope of this License.
However, linking a "work that uses the Library" with the Library creates an executable that is
a derivative of the Library (because it contains portions of the Library), rather than a "work
that uses the library". The executable is therefore covered by this License. Section 6 states
terms for distribution of such executables.
When a "work that uses the Library" uses material from a header file that is part of the Library,
the object code for the work may be a derivative work of the Library even though the source
code is not. Whether this is true is especially significant if the work can be linked without the
Library, or if the work is itself a library. The threshold for this to be true is not precisely
defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and small inline functions (ten lines or less
in length), then the use of the object file is unrestricted, regardless of whether it is legally a
derivative work. (Executables containing this object code plus portions of the Library will still
fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may distribute the object code for the
work under the terms of Section 6. Any executables containing that work also fall under
Section 6, whether or not they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or link a "work that uses the
Library" with the Library to produce a work containing portions of the Library, and distribute
that work under terms of your choice, provided that the terms permit
modification of the work for the customer's own use and reverse engineering for debugging
such modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by
this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the
copyright notice for the Library among them, as well as a reference
directing the user to the copy of this License. Also, you must do one
of these things:
a) Accompany the work with the complete corresponding
machine-readable source code for the Library including whatever
changes were used in the work (which must be distributed under
Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the
complete machine-readable "work that
uses the Library", as object code and/or source code, so that the user can modify the Library
and then relink to produce a modified executable containing the modified Library. (It is
understood
that the user who changes the contents of definitions files in the Library will not necessarily be
able to recompile the application to use the modified definitions.)
