a work based on the Library) on a volume of a
storage or distribution medium does not bring the
other work under the scope of this License.
You may opt to apply the terms of the ordinary GNU
3.
General Public License instead of this License to a
given copy of the Library. To do this, you must alter all
the notices that refer to this License, so that they refer
to the ordinary GNU General Public License, version
2, instead of to this License. (If a newer version than
version 2 of the ordinary GNU General Public License
has appeared, then you can specify that version
instead if you wish.) Do not make any other change in
these notices.
Once this change is made in a given copy, it is
irreversible for that copy, so the ordinary GNU General
Public License applies to all subsequent copies and
derivative works made from that copy.
This option is useful when you wish to copy part of the
code of the Library into a program that is not a library.
You may copy and distribute the Library (or a portion
4.
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.
A program that contains no derivative of any portion
5.
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.
As an exception to the Sections above, you may also
6.
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:
Accompany the work with the complete
a)
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.)
Use a suitable shared library mechanism for linking
b)
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.
