The GNU C++ Library is part of GCC and follows the same development model,
so the general rules for
< a class = "link" href = "http://gcc.gnu.org/contribute.html" target = "_top" > contributing
to GCC< / a > apply. Active
contributors are assigned maintainership responsibility, and given
write access to the source repository. First-time contributors
2012-03-27 23:13:14 +00:00
should follow this procedure:
2014-09-21 17:33:12 +00:00

Get and read the relevant sections of the C++ language
specification. Copies of the full ISO 14882 standard are
available on line via the ISO mirror site for committee
members. Non-members, or those who have not paid for the
privilege of sitting on the committee and sustained their
two meeting commitment for voting rights, may get a copy of
the standard from their respective national standards
organization. In the USA, this national standards
organization is

Historically, the libstdc++ assignment form added the following
question:

< span class = "quote" > “< span class = "quote" >
Which Belgian comic book character is better, Tintin or Asterix, and
why?

While not strictly necessary, humoring the maintainers and answering
this question would be appreciated.

Every patch must have several pieces of information before it can be
properly evaluated. Ideally (and to ensure the fastest possible
response from the maintainers) it would have all of these pieces:

A description of the bug and how your patch fixes this
bug. For new features a description of the feature and your
implementation.
< / p > < / li > < li class = "listitem" > < p >
A ChangeLog entry as plain text; see the various
ChangeLog files for format and content. If you are
using emacs as your editor, simply position the insertion
point at the beginning of your change and hit CX-4a to bring
up the appropriate ChangeLog entry. See--magic! Similar
functionality also exists for vi.
< / p > < / li > < li class = "listitem" > < p >
A testsuite submission or sample program that will
easily and simply show the existing error or test new
functionality.
< / p > < / li > < li class = "listitem" > < p >
The patch itself. If you are accessing the SVN
repository use < span class = "command" > < strong > svn update; svn diff NEW< / strong > < / span > ;
else, use < span class = "command" > < strong > diff -cp OLD NEW< / strong > < / span > ... If your
version of diff does not support these options, then get the
latest version of GNU

When you have all these pieces, bundle them up in a
mail message and send it to libstdc++@gcc.gnu.org. All
patches and related discussion should be sent to the
2017-04-10 11:32:00 +00:00
libstdc++ mailing list. In common with the rest of GCC,
patches should also be sent to the gcc-patches mailing list.
