 1.7 What happened to libg++? I need that!
 
    The most recent libg++ README states that libg++ is no longer being
    actively maintained. It should not be used for new projects, and is
    only being kicked along to support older code.
-
+   
    The libg++ was designed and created when there was no Standard to
    provide guidance. Classes like linked lists are now provided for by
    list<T> and do not need to be created by genclass. (For that matter,
    templates exist now and are well-supported, whereas genclass (mostly)
    predates them.)
-
+   
    There are other classes in libg++ that are not specified in the ISO
    Standard (e.g., statistical analysis). While there are a lot of really
    useful things that are used by a lot of people (e.g., statistics :-),
    the Standards Committee couldn't include everything, and so a lot of
    those "obvious" classes didn't get included.

 2.2 Is this a drop-in replacement for the libstdc++ that's shipped with g++?
 
    Yes, as of 2.90.8, it is intended as such.

    The installation instructions cover this in more detail, but replacing
    the older library requires rebuilding some of the code that comes with
    g++. You will need sources for the 2.95.2 compiler in order to build
    this snapshot. Building the library on its own and then using -I/-L
    will no longer work.

-

 2.4 How do I know if it works?
 
    libstdc++-v3 comes with its own testsuite. You do not need to actually
    install the library ("gmake install") to run the testsuite.
-
+   
    To run the testsuite on the library after building it, use "gmake
    check" while in your build directory. To run the testsuite on the
    library after building and installing it, use "gmake check-install"
    instead.
-
+   
    The testsuite subdirectory in your build directory will then contain
    three files of the form YYYYMMDD-mkcheck*.txt. One of them
    (-mkcheck.txt itself) contains the results of the tests; this can be
    mailed to the list. The other files (-mkchecklog.txt and
    -mkcheckfiles.txt) contain messages from the compiler while building
    the test programs, and a list of the tests to be run, respectively.
-
+   
    If you are using the libgcc.a-rebuilding method to enable std:: you
    might find that the testsuite starts dying with nasty linker errors.
    This is symptomatic of the rebuilt libgcc.a not being installed; the
    previous one is still in use.
-
+   
    If you find bugs in the testsuite programs themselves, or if you think
    of a new test program that should be added to the suite, please write
    up your idea and send it to the list!

 3.1 Can libstdc++-v3 be used with <my favorite compiler>?
 
    Probably not. Yet.

    is being done almost entirely under that compiler. If you are curious

    (see above) will still require certain tools, however. Also keep in
    mind that building libstdc++ does not imply that your compiler will be
    able to use all of the features found in the C++ Standard Library.
-
+   
    Since the goal of ISO Standardization is for all C++ implementations
    to be able to share code, the final libstdc++ should, in theory, be
    useable under any ISO-compliant compiler. It will still be targeted
    and optimized for GCC/g++, however.

 3.2 Building under Cygwin hangs/explodes!?
 
    Sometimes, yes. You're probably in the middle of generating the
    numeric_limits specializations when it hangs, right? Thought so...
-
+   
    The <limits> header and its associated library code are
    platform-specific. These files get generated from scratch during
    installation, and it is this generator that is hanging. More
    specifically, the only sure way to determine what the
    numeric_limits<T>::traps boolean should be is to actually divide by
    zero and see if it is trapped or not.
-
+   
    Under NT, this will occasionally just hang. On those occasions when
    the test does not hang, the zero-division is in fact trapped. That
    doesn't prevent hanging elsewhere.
-
+   
    You have two options. You can get a newer cygwin1.dll (see the Cygwin
    paragraph in the [54]installation instructions). Or you can get a
    prebuilt set of bits/std_limits.h and src/limitsMEMBERS.cc files from
    Mumit Khan's [55]Cygwin-related website.

    For those people who are not part of the ISO Library Group (i.e.,
    nearly all of us needing to read this page in the first place :-), a
    public list of the library defects is occasionally published [58]here.

 4.4 Things in libstdc++ that look like bugs
 
    There are things which are not bugs in the compiler (4.2) nor the
    language specification (4.3), but aren't really bugs in libstdc++,
    either. Really!
-
+   
    The biggest of these is the quadzillions of warnings about the library
    headers emitted when -Weffc++ is used. Making libstdc++
    "-Weffc++-clean" is not a goal of the project, for a few reasons.

    how to submit patches.

    is a Good Thing if you can additionally create a small test program to

 5.1 string::iterator is not char*; vector<T>::iterator is not T*
 
    If you have code that depends on container<T> iterators being
    implemented as pointer-to-T, your code is broken.
-
+   
    While there are arguments for iterators to be implemented in that
    manner, A) they aren't very good ones in the long term, and B) they
    were never guaranteed by the Standard anyway. The type-safety achieved
    by making iterators a real class rather than a typedef for T*
    outweighs nearly all opposing arguments.
      _________________________________________________________________
-
+   
 5.2 What's next after libstdc++-v3?
 
    Hopefully, not much. The goal of libstdc++-v3 is to produce a
    fully-compliant, fully-portable Standard Library. After that, we're
    mostly done: there won't be any more compliance work to do.
-
+   
    The ISO Committee will meet periodically to review Defect Reports in
    the C++ Standard. Undoubtably some of these will result in changes to
    the Standard, which will be reflected in patches to libstdc++. Some of
    that is already happening, see 4.2. Some of those changes are being
    predicted by the library maintainers, and we add code to the library
    based on what the current proposed resolution specifies.
-
+   
    The current libstdc++ contains extensions to the Library which must be
    explicitly requested by client code (for example, the hash tables from
    SGI). Other extensions may be added to libstdc++-v3 if they seem to be
    "standard" enough. (For example, the "long long" type from C99.)
    Bugfixes and rewrites (to improve or fix thread safety, for instance)
    will of course be a continuing task.
-
+   
    [62]This question about the next libstdc++ prompted some brief but
    interesting [63]speculation.
      _________________________________________________________________
-
+   
 5.3 What about the STL from SGI?
 
    The [64]STL from SGI is merged into libstdc++-v3 with changes as
    necessary. Currently release 3.3 is being used. Changes in the STL
    usually produce some weird bugs and lots of changes in the rest of the
    libstd++ source as we scramble to keep up. :-)
-
+   
    In particular, string is not from SGI and makes no use of their "rope"
    class (which is included as an optional extension), nor is valarray
    and some others. Classes like vector<> are, however.
-
+   
    The FAQ for SGI's STL (one jump off of their main page) is recommended
    reading.

    your libraries each time you get a new compiler snapshot.)

    Towards the end of July 1999, this subject was brought up again on the
    mailing list under a different name. The related [66]thread (by the
    name HOWTO-honor-std) is very instructive. More info is at the end of
    RELEASE-NOTES.

    This functionality is now automated and turned on by default.

 5.6 Is libstdc++-v3 thread-safe?
 
    Quick answer: no, as of 2.90.8 (ninth snapshot), the library is not
    appropriate for multithreaded access. The string class is MT-safe.
-
+   
    This is assuming that your idea of "multithreaded" is the same as
    ours... The general question of multithreading and libstdc++-v3 is
    addressed in the chapter-specific advice for [67]Library Introduction.
    Threadsafe containers are covered in more detail in [68]the Received
    Wisdom section on containers.
