<p>There are two licenses affecting GNU libstdc++-v3: one for the code, and
|
|
one for the documentation. Here we will describe both of them, and try
|
|
to answer some of the widespread questions. If you have more questions,
|
|
ask the FSF or the
|
|
<a href="http://gcc.gnu.org/lists.html">gcc mailing list</a>; the person
|
|
writing this page is a programmer, not a lawyer.

<h2>The Code: Runtime GPL</h2>
|
|
|
|
<p>The source code of libstdc++-v3 is distributed under version 2 of the
|
|
<a href="COPYING">GNU General Public License</a>, with the so-called
|
|
"runtime exception," as follows (or see any header or
|
|
implementation file):
|
|
<pre>
|
|
As a special exception, you may use this file as part of a free software
|
|
library without restriction. Specifically, if other files instantiate
|
|
templates or use macros or inline functions from this file, or you compile
|
|
this file and link it with other files to produce an executable, this
|
|
file does not by itself cause the resulting executable to be covered by
|
|
the GNU General Public License. This exception does not however
|
|
invalidate any other reasons why the executable file might be covered by
|
|
the GNU General Public License.
|
|
</pre>
|
|
</p>
|
|
|
|
<p>Hopefully that text is self-explanatory. If it isn't, you need to speak
|
|
to your lawyer, or the Free Software Foundation.

<!-- Most of the Q&A's are based on, paraphrased from, and outright stolen
|
|
from this thread:
|
|
http://gcc.gnu.org/ml/libstdc++/2000-q2/subjects.html#00050
|
|
-->
|
|
<p><strong>Q: So any program which uses libstdc++ falls under the GPL?</strong>
|
|
<br>A: <strong>No.</strong> The special exception permits use of the
|
|
library in proprietary applications.
|
|
</p>
|
|
|
|
<p><strong>Q: How is that different from the GNU {Lesser,Library}
|
|
GPL?</strong>
|
|
<!-- Quoting Jason Merrill from the thread above: -->
|
|
<br>A: The LGPL requires that users be able to replace the LGPL code with a
|
|
modified version; this is trivial if the library in question is a C
|
|
shared library. But there's no way to make that work with C++, where
|
|
much of the library consists of inline functions and templates, which
|
|
are expanded inside the code that uses the library. So to allow people
|
|
to replace the library code, someone using the library would have to
|
|
distribute their own source, rendering the LGPL equivalent to the GPL.
|
|
</p>
|
|
|
|
<p><strong>Q: I see. So, what restrictions <em>are</em> there on
|
|
programs that use the library?</strong>
|
|
<br>A: None. We encourage such programs to be released as open source,
|
|
but we won't punish you or sue you if you choose otherwise.

<h2>The Docs: FDL</h2>
|
|
|
|
<p>The documentation shipped with the library and made available over the
|
|
web, including the pages generated from source comments, are copyrighted
|
|
by the Free Software Foundation, and placed under
|
|
the <a href="COPYING.DOC">GNU Free Documentation License version 1.1</a>.
|
|
There are no Front-Cover Texts, no Back-Cover Texts, and
|
|
<!-- as far as I know -->
|
|
no Invariant Sections.
|
|
</p>
|
|
|
|
<p>If you plan on making copies of the documentation, please let us know.
|
|
We can probably offer suggestions.
