The <code class="filename">libstdc++-v3</code> directory in the
GCC sources contains the files needed to create the GNU C++ Library.
- </p><div class="literallayout"><p><br />
-It has subdirectories:<br />
-<br />
- <code class="filename">doc</code><br />
- Files in HTML and text format that document usage, quirks of the<br />
- implementation, and contributor checklists.<br />
-<br />
- <code class="filename">include</code><br />
- All header files for the C++ library are within this directory,<br />
- modulo specific runtime-related files that are in the libsupc++<br />
- directory.<br />
-<br />
- <code class="filename">include/std</code><br />
- Files meant to be found by #include <name> directives in<br />
- standard-conforming user programs.<br />
-<br />
- <code class="filename">include/c</code><br />
- Headers intended to directly include standard C headers.<br />
- [NB: this can be enabled via <code class="option">--enable-cheaders=c</code>]<br />
-<br />
- <code class="filename">include/c_global</code><br />
- Headers intended to include standard C headers in<br />
- the global namespace, and put select names into the std::<br />
- namespace. [NB: this is the default, and is the same as<br />
- <code class="option">--enable-cheaders=c_global</code>]<br />
-<br />
- <code class="filename">include/c_std</code><br />
- Headers intended to include standard C headers<br />
- already in namespace std, and put select names into the std::<br />
- namespace. [NB: this is the same as<br />
- <code class="option">--enable-cheaders=c_std</code>]<br />
-<br />
- <code class="filename">include/bits</code><br />
- Files included by standard headers and by other files in<br />
- the bits directory.<br />
-<br />
- <code class="filename">include/backward</code><br />
- Headers provided for backward compatibility, such as <iostream.h>.<br />
- They are not used in this library.<br />
-<br />
- <code class="filename">include/ext</code><br />
- Headers that define extensions to the standard library. No<br />
- standard header refers to any of them.<br />
-<br />
- <code class="filename">scripts</code><br />
- Scripts that are used during the configure, build, make, or test<br />
- process.<br />
-<br />
- <code class="filename">src</code><br />
- Files that are used in constructing the library, but are not<br />
- installed.<br />
-<br />
- <code class="filename">src/c++98</code><br />
- Source files compiled using <code class="option">-std=gnu++98</code>.<br />
-<br />
- <code class="filename">src/c++11</code><br />
- Source files compiled using <code class="option">-std=gnu++11</code>.<br />
-<br />
- <code class="filename">src/filesystem</code><br />
- Source files for the Filesystem TS.<br />
-<br />
- <code class="filename">src/shared</code><br />
- Source code included by other files under both<br />
- <code class="filename">src/c++98</code> and<br />
- <code class="filename">src/c++11</code><br />
-<br />
- <code class="filename">testsuites/[backward, demangle, ext, performance, thread, 17_* to 30_*]</code><br />
- Test programs are here, and may be used to begin to exercise the<br />
- library. Support for "make check" and "make check-install" is<br />
- complete, and runs through all the subdirectories here when this<br />
- command is issued from the build directory. Please note that<br />
- "make check" requires DejaGNU 1.4 or later to be installed.<br />
-<br />
-Other subdirectories contain variant versions of certain files<br />
-that are meant to be copied or linked by the configure script.<br />
-Currently these are:<br />
-<br />
- <code class="filename">config/abi</code><br />
- <code class="filename">config/cpu</code><br />
- <code class="filename">config/io</code><br />
- <code class="filename">config/locale</code><br />
- <code class="filename">config/os</code><br />
-<br />
-In addition, a subdirectory holds the convenience library libsupc++.<br />
-<br />
- <code class="filename">libsupc++</code><br />
- Contains the runtime library for C++, including exception<br />
- handling and memory allocation and deallocation, RTTI, terminate<br />
- handlers, etc.<br />
-<br />
-Note that glibc also has a <code class="filename">bits/</code><br />
-subdirectory. We will either need to be careful not to collide with names<br />
-in its <code class="filename">bits/</code><br />
-directory; or rename <code class="filename">bits</code> to (e.g.) <code class="filename">cppbits</code>.<br />
-<br />
-In files throughout the system, lines marked with an "XXX" indicate<br />
-a bug or incompletely-implemented feature. Lines marked "XXX MT"<br />
-indicate a place that may require attention for multi-thread safety.<br />
