Calc's relationship to the GNU Lesser General Public License
|
|
------------------------------------------------------------
|
|
|
|
In section 0 of the GNU Lesser General Public License, one finds
|
|
the following definition:
|
|
|
|
The "Library", below, refers to any such software library or
|
|
work which has been distributed under these terms.
|
|
|
|
Calc is distributed under the terms of the GNU Lesser
|
|
General Public License.
|
|
|
|
In the same section 0, one also find the following:
|
|
|
|
For a library, complete source code means all the source code
|
|
for all modules it contains, plus any associated interface
|
|
definition files, plus the scripts used to control compilation
|
|
and installation of the library.
|
|
|
|
There are at least two calc binary link libraries found in calc:
|
|
|
|
libcalc.a libcustcalc.a
|
|
|
|
Clearly all files that go into the creation of those binary link
|
|
libraries are covered under the License.
|
|
|
|
The "scripts used to control compilation and installation of the
|
|
of the library" include:
|
|
|
|
* Makefiles
|
|
* source files created by the Makefiles
|
|
* source code used in the creation of intermediate source files
|
|
|
|
All of those files are covered under the License.
|
|
|
|
The "associated interface definition files" are those files that:
|
|
|
|
* show how the calc binary link libraries are used
|
|
* test the validity of the binary link libraries
|
|
* document routines found in the binary link libraries
|
|
* show how one can interactively use the binary link libraries
|
|
|
|
Calc provides an extensive set of files that perform the above
|
|
functions.
|
|
|
|
* files under the sample sub-directory
|
|
* files under the help sub-directory
|
|
* files under the lib sub-directory
|
|
* the main calc.c file
|
|
|
|
The "complete source code" includes ALL files shipped with calc,
|
|
except for the exception files explicitly listed in the "Calc
|
|
copyrights and exception files" section below.

Why calc did not use the GNU General Public License
|
|
---------------------------------------------------
|
|
|
|
It has been suggested that one should consider using the GNU General
|
|
Public License instead of the GNU Lesser General Public License:
|
|
|
|
http://www.gnu.org/philosophy/why-not-lgpl.html
|
|
|
|
As you can read in the above URL, there are times where a library
|
|
cannot give free software any particular advantage. One of those
|
|
times is when there is significantly similar versions available
|
|
that are not covered under a Copyleft such as the GNU General Public
|
|
License.
|
|
|
|
The reason why calc was placed under the GNU Lesser General Public
|
|
License is because for many years (1984 thru 1999), calc was offered
|
|
without any form of Copyleft. At the time calc was placed under
|
|
the GNU Lesser General Public License, a number of systems and
|
|
distributions distributed calc without a Copyleft.
