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.)
b) Use a suitable shared library mechanism for linking
withthe Library. A suitable mechanism is one that (1)
uses at run time a copy of the library already present
on the user's computer system, rather than copying
library functions into the executable, and (2) will operate
properly with a modified version of the library, if the
user installs one, as long as the modified version is
interface-compatible with the version that the work
was made with.
c) Accompany the work with a written offer, valid for at
least three years, to give the same user the materials
specified in Subsection 6a, above, for a charge no more
than the cost of performing this distribution.
d) If distribution of the work is made by offering access
to copy from a designated place, offer equivalent
access to copy the above specified materials from the
same place.
e) Verify that the user has already received a copy of
these materials or that you have already sent this user a
copy. For an executable, the required form of the "work
that uses the Library" must include any data and utility
programs needed for reproducing the executable from
it. However, as a special exception, the materials to be
distributed need not include anything that is normally
distributed (in either source or binary form) with the
major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless
that component itself accompanies the executable.
It may happen that this requirement contradicts the
license restrictions of other proprietary libraries that do
not normally accompany the operating system. Such a
contradiction means you cannot use both them and the
Library together in an executable that you distribute.
7. You may place library facilities that are a work based on the
Library side-by-side in a single library together with other
library facilities not covered by this License, and distribute
such a combined library, provided that the separate
distribution of the work based on the Library and of the
other library facilities is otherwise permitted, and provided
that you do these two things:
a) Accompany the combined library with a copy of the
same work based on the Library, uncombined with any
other library facilities. This must be distributed under the
terms of the Sections above.
b) Give prominent notice with the combined library of the
fact that part of it is a work based on the Library, and
explaining where to find the accompanying uncombined
form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute
the Library except as expressly provided under this License.
Any attempt otherwise to copy, modify, sublicense, link with,
or distribute the Library is void, and will automatically terminate
your rights under this License. However, parties who have
received copies, or rights, from you under this License will not
have their licenses terminated so long as such parties remain
in full compliance.
9. You are not required to accept this License, since you
have not signed it. However, nothing else grants you
permission to modify or distribute the Library or its
derivative works. These actions are prohibited by law if
you do not accept this License. Therefore, by modifying or
distributing the Library (or any work based on the Library),
you indicate your acceptance of this License to do so,
and all its terms and conditions for copying, distributing or
modifying the Library or works based on it.
10. Each time you redistribute the Library (or any work based
on the Library), the recipient automatically receives a
license from the original licensor to copy, distribute, link
with or modify the Library subject to these terms and
conditions. You may not impose any further restrictions
on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third
parties with this License.
11. If, as a consequence of a court judgment or allegation of
patent infringement or for any other reason (not limited to
patent issues), conditions are imposed on you (whether by
court order, agreement or otherwise) that contradict the
conditions of this License, they do not excuse you from
the conditions of this License. If you cannot istribute so as
to satisfy simultaneously your obligations nder this License
and any other pertinent obligations, then as a consequence
you may not distribute the Library at all. For example, if a
patent license would not permit royalty free redistribution
of the Library by all those who receive copies directly or
indirectly through you, then the only way you could satisfy
both it and this License would be to refrain entirely from
distribution of the Library.
