3 New users may wish to point their web browsers to the file documentation.html
4 in the 'docs/html' subdirectory. It contains brief building instructions and
5 notes on how to configure the library in interesting ways.
7 Instructions for configuring and building appear in
8 docs/html/install.html.
10 This directory contains the files needed to create an ISO Standard C++
13 It has subdirectories:
16 Files in HTML and text format that document usage, quirks of the
17 implementation, and contributor checklists.
20 Files meant to be found by #include <name> directives in
21 standard-conforming user programs.
24 Headers intended to directly include standard C headers.
25 [NB: this can be enabled via --enable-cheaders=c]
28 Headers intended to include standard C headers, and put select
29 names into the std:: namespace.
30 [NB: this is the default, and is the same as --enable-cheaders=c_std]
33 Headers intended to shadow standard C headers provided by an
34 underlying OS or C library, and other headers depended on directly
35 by C++ headers (e.g. unistd.h). These are meant to wrap the names
36 defined there into the _C_legacy namespace.
37 [NB: this can be enabled via --enable-cheaders=c_shadow]
40 Files included by standard headers and by other files in
44 Headers provided for backward compatibility, such as <iostream.h>.
45 They are not used in this library.
48 Headers that define extensions to the standard library. No
49 standard header refers to any of them.
52 Files that are used in constructing the library, but are not
55 testsuites/[thread, 17_* to 27_*]
56 Test programs are here, and may be used to begin to exercise the
57 library. Support for "make check" and "make check-install" is
58 complete, and runs through all the subdirectories here when this
59 command is issued from the build directory. Please note that
60 "make check" requires DejaGNU 1.4 or later to be installed. Please
61 note that "make check-script" calls the script mkcheck, which
62 requires bash, and which may need the paths to bash adjusted to
63 work properly, as /bin/bash is assumed.
65 Other subdirectories contain variant versions of certain files
66 that are meant to be copied or linked by the configure script.
74 In addition, three subdirectories are convenience libraries:
77 Contains the subset of the GNU libio library needed for
78 C++. Currently not used.
81 Support routines needed for C++ math. Only needed if the
82 underlying "C" implementation is weak or looses.
85 Contains the runtime library for C++, including exception
86 handling and memory allocation and deallocation, RTTI, terminate
89 Note that glibc also has a bits/ subdirectory. We will either
90 need to be careful not to collide with names in its bits/
91 directory; or rename bits to (e.g.) cppbits/.
93 In files throughout the system, lines marked with an "XXX" indicate
94 a bug or incompletely-implemented feature. Lines marked "XXX MT"
95 indicate a place that may require attention for multi-thread safety.
