the requirement to distribute the source code, even though third parties are not com-
pelled to copy the source along with the object code.
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 there-
fore 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 acces-
sors, 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 modifi-
cation 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.)
