4. You may copy and distribute the Library (or a portion or
derivative of it, under Section 2) in object code or executable
form under the terms of Sections 1 and 2 above provided
that you accompany it with the complete corresponding
machine-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 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
