file: libstdc++-v3/README
-New users may wish to point their web browsers to the file documentation.html
-in the 'docs/html' subdirectory. It contains brief building instructions and
-notes on how to configure the library in interesting ways.
-
-Instructions for configuring and building appear in
-docs/html/install.html.
-
-This directory contains the files needed to create an ISO Standard C++
-Library.
-
-It has subdirectories:
-
- docs
- Files in HTML and text format that document usage, quirks of the
- implementation, and contributor checklists.
-
- include/std
- Files meant to be found by #include <name> directives in
- standard-conforming user programs.
-
- include/c
- Headers intended to directly include standard C headers.
- [NB: this can be enabled via --enable-cheaders=c]
-
- include/c_std
- Headers intended to include standard C headers, and put select
- names into the std:: namespace.
- [NB: this is the default, and is the same as --enable-cheaders=c_std]
-
- include/c_shadow
- Headers intended to shadow standard C headers provided by an
- underlying OS or C library, and other headers depended on directly
- by C++ headers (e.g. unistd.h). These are meant to wrap the names
- defined there into the _C_legacy namespace.
- [NB: this can be enabled via --enable-cheaders=c_shadow]
-
- include/bits
- Files included by standard headers and by other files in
- the bits directory.
-
- include/backward
- Headers provided for backward compatibility, such as <iostream.h>.
- They are not used in this library.
-
- include/ext
- Headers that define extensions to the standard library. No
- standard header refers to any of them.
-
- src
- Files that are used in constructing the library, but are not
- installed.
-
- testsuites/[thread, 17_* to 27_*]
- Test programs are here, and may be used to begin to exercise the
- library. Support for "make check" and "make check-install" is
- complete, and runs through all the subdirectories here when this
- command is issued from the build directory. Please note that
- "make check" requires DejaGNU 1.4 or later to be installed. Please
- note that "make check-script" calls the script mkcheck, which
- requires bash, and which may need the paths to bash adjusted to
- work properly, as /bin/bash is assumed.
-
-Other subdirectories contain variant versions of certain files
-that are meant to be copied or linked by the configure script.
-Currently these are:
-
- config/cpu
- config/os
- config/io
- config/locale
-
-In addition, three subdirectories are convenience libraries:
-
- libio
- Contains the subset of the GNU libio library needed for
- C++. Currently not used.
-
- libmath
- Support routines needed for C++ math. Only needed if the
- underlying "C" implementation is weak or looses.
-
- libsupc++
- Contains the runtime library for C++, including exception
- handling and memory allocation and deallocation, RTTI, terminate
- handlers, etc.
-
-Note that glibc also has a bits/ subdirectory. We will either
-need to be careful not to collide with names in its bits/
-directory; or rename bits to (e.g.) cppbits/.
-
-In files throughout the system, lines marked with an "XXX" indicate
-a bug or incompletely-implemented feature. Lines marked "XXX MT"
-indicate a place that may require attention for multi-thread safety.
