|
||
The unpacked source directory of libstdc++ contains the files
|
||
needed to create the GNU C++ Library.
|
||
</p><div class="literallayout"><p><br />
|
||
It has subdirectories:<br />
|
||
<br />
|
||
doc<br />
|
||
Files in HTML and text format that document usage, quirks of the<br />
|
||
implementation, and contributor checklists.<br />
|
||
<br />
|
||
include<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 />
|
||
include/std<br />
|
||
Files meant to be found by #include <name> directives in<br />
|
||
standard-conforming user programs.<br />
|
||
<br />
|
||
include/c<br />
|
||
Headers intended to directly include standard C headers.<br />
|
||
[NB: this can be enabled via --enable-cheaders=c]<br />
|
||
<br />
|
||
include/c_global<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 />
|
||
--enable-cheaders=c_global]<br />
|
||
<br />
|
||
include/c_std<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 --enable-cheaders=c_std]<br />
|
||
<br />
|
||
include/bits<br />
|
||
Files included by standard headers and by other files in<br />
|
||
the bits directory.<br />
|
||
<br />
|
||
include/backward<br />
|
||
Headers provided for backward compatibility, such as <iostream.h>.<br />
|
||
They are not used in this library.<br />
|
||
<br />
|
||
include/ext<br />
|
||
Headers that define extensions to the standard library. No<br />
|
||
standard header refers to any of them.<br />
|
||
<br />
|
||
scripts<br />
|
||
Scripts that are used during the configure, build, make, or test<br />
|
||
process.<br />
|
||
<br />
|
||
src<br />
|
||
Files that are used in constructing the library, but are not<br />
|
||
installed.<br />
|
||
<br />
|
||
testsuites/[backward, demangle, ext, performance, thread, 17_* to 27_*]<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. Please<br />
|
||
note that "make check-script" calls the script mkcheck, which<br />
|
||
requires bash, and which may need the paths to bash adjusted to<br />
|
||
work properly, as /bin/bash is assumed.<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 />
|
||
config/abi<br />
|
||
config/cpu<br />
|
||
config/io<br />
|
||
config/locale<br />
|
||
config/os<br />
|
||
<br />
|
||
In addition, a subdirectory holds the convenience library libsupc++.<br />
|
||
<br />
|
||
libsupc++<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 bits/ subdirectory. We will either<br />
|
||
need to be careful not to collide with names in its bits/<br />
|
||
directory; or rename bits to (e.g.) cppbits/.<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 />
