ry into a program that is not a library.
You may copy and distribute the Library (or
4.
a portion 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 cor-
responding 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 designa-
ted place, then offering equivalent ac-
cess 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
5.
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 there-
fore falls outside the scope of this License.
However, linking a «work that uses the
Library» with the Library creates an exe-
cutable that is a derivative of the Library
(because it contains portions of the Li-
brary), rather than a «work that uses the
library». The executable is therefore co-
vered 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 numeri-
cal 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,
