3 New users may wish to point their web browsers to the file
4 documentation.html in the 'docs/html' subdirectory. It contains brief
5 building instructions and notes on how to configure the library in
8 Instructions for configuring and building appear in
9 docs/html/install.html.
11 This directory contains the files needed to create an ISO Standard C++
14 It has subdirectories:
17 Files in HTML and text format that document usage, quirks of the
18 implementation, and contributor checklists.
21 All header files for the C++ library are within this directory,
22 modulo specific runtime-related files that are in the libsupc++
26 Files meant to be found by #include <name> directives in
27 standard-conforming user programs.
30 Headers intended to directly include standard C headers.
31 [NB: this can be enabled via --enable-cheaders=c]
34 Headers intended to include standard C headers, and put select
35 names into the std:: namespace.
36 [NB: this is the default, and is the same as --enable-cheaders=c_std]
39 Files included by standard headers and by other files in
43 Headers provided for backward compatibility, such as <iostream.h>.
44 They are not used in this library.
47 Headers that define extensions to the standard library. No
48 standard header refers to any of them.
51 Scripts that are used during the configure, build, make, or test
55 Files that are used in constructing the library, but are not
58 testsuites/[backward, demangle, ext, performance, thread, 17_* to 27_*]
59 Test programs are here, and may be used to begin to exercise the
60 library. Support for "make check" and "make check-install" is
61 complete, and runs through all the subdirectories here when this
62 command is issued from the build directory. Please note that
63 "make check" requires DejaGNU 1.4 or later to be installed. Please
64 note that "make check-script" calls the script mkcheck, which
65 requires bash, and which may need the paths to bash adjusted to
66 work properly, as /bin/bash is assumed.
68 Other subdirectories contain variant versions of certain files
69 that are meant to be copied or linked by the configure script.
78 In addition, two subdirectories are convenience libraries:
81 Support routines needed for C++ math. Only needed if the
82 underlying "C" implementation is non-existent, in particular
83 required or optimal long double, long long, and C99 functionality.
86 Contains the runtime library for C++, including exception
87 handling and memory allocation and deallocation, RTTI, terminate
90 Note that glibc also has a bits/ subdirectory. We will either
91 need to be careful not to collide with names in its bits/
92 directory; or rename bits to (e.g.) cppbits/.
94 In files throughout the system, lines marked with an "XXX" indicate
95 a bug or incompletely-implemented feature. Lines marked "XXX MT"
96 indicate a place that may require attention for multi-thread safety.
