APPENDIX
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 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 with the 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
