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.
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.
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.
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.
?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.
If any portion of this section is held invalid or
unenforceable under any particular circumstance, the
balance of the section is intended to apply, and the
section as a whole is intended to apply in other
circumstances.
