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
110
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
