file: libstdc++-v3/README
-New users may wish to point their web browsers to the file index.html
-in the 'docs' subdirectory. It contains brief building instructions
-and notes on how to configure the library in interesting ways.
-
-
-Instructions for configuring and building this snapshot appear
-in install.html.
-
-This directory contains the files needed to create [a still broken
-subset of] 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/bits
- Files included by standard headers and by other files in
- the bits directory. Includes a set of files bits/std_xxxx.h
- that implement the standard headers <xxxx>.
-
- include/std
- Files meant to be found by #include <name> directives in
- standard-conforming user programs. These headers are not
- referred to by other headers, because such dependencies
- confuse Make (leading it to delete them, all too often).
- Installations may substitute symbolic links in place of
- these files.
-
- include/ext
- Headers that define extensions to the standard library. No
- standard header refers to any of them.
-
- include/backward
- Headers provided for backward compatibility, such as <iostream.h>.
- They are not used in this library.
-
- src
- Files that are used in constructing the library, but are not
- installed.
-
- testsuites/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" calls the script mkcheck, which requires bash, and which
- may need the paths to bash adjusted to work properly, as /bin/bash is
- assumed.
-
- 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-cshadow-headers.]
-
- cshadow
- The contents of this directory are constructed by scripts which
- examine the underlying C headers to discover other headers they
- depend on. These headers are wrappers for them.
- [NB: this is still experimental, and is not currently used.]
-
-Other subdirectories contain variant versions of certain files
-that are meant to be copied or linked by the configure script.
-Currently these are:
-
- math
- config/cpu
- config/os
-
-Files needed only to construct the library, but not installed,
-are in src/. Files to be copied as part of an installation are
-all found in the subdirectories mentioned above. (A configure
-script may link files from another directory into one of these.)
-
-In a normal installation the bits/ directory is copied
-under the std/ directory, and arranged to be searched only
-when an include directive specifies a filename of "bits/..."
-or <bits/...>. When building the library, we use
-
- -I. -Iinclude/std -Iinclude -Iconfig/os/* -Iconfig/cpu/*
-
-to get the same effect.
-
-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/.
-
-To install libstdc++ you need GNU make. The makefiles do not work with
-any other make.
-
-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.
