readable source code, which must be distributed under the terms of Sections 1
and 2 above on a medium customarily used for software interchange. If
distribution of object code is made by offering access to copy from a designated
place, then offering equivalent access to copy the source code from the same
place satisfies the requirement to distribute the source code, even though third
parties are not
compelled 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 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
accessories, 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-
