Big integer library
by Marcin Kalici�ski 19 May '05

19 May '05

Tracking the disussion on n1774 'Big integer library proposal for C++0x' I see there is a lot of controversy about it, and it will probably need much tweaking before (if ever) it is accepted. Wouldn't that be a good idea to have a big integer added to boost so that we can create a 'working practice' before anything gets standarised? I have some preliminary source code, some spare time, and would volunteer to work on it if there's enough interest. cheers, M.

[Iterator] advance and distance that understand new iterator concepts?
by Douglas Gregor 19 May '05

19 May '05

Do we have counterparts to std::advance and std::distance that are optimized for random_access_traversal_tag instead of std::random_access_iterator_tag? Doug

[Wave] Boost Inspection Report
by Hartmut Kaiser 19 May '05

19 May '05

Hi all, the boost inspection report claims that one of the Wave test files contains tabs. And this is correct! But: it needs to contain tabs because it's a testcase... Should I ignore this warning? Or is there a way to tell the inspect program to ignore tabs in this particular file? Regards Hartmut

xpressive not in boost.1.33, but what about 1.34?
by Bronek Kozicki 19 May '05

19 May '05

I suppose xpressive has not been accepted into boost yet (or I missed library review). This would mean that we will not see it in boost 1.33. Is there any chance we would see it in boost 1.34? B. -- Bronek Kozicki brok(a)rubikon.pl http://b.kozicki.pl/

[operators] Improved workaround for BOOST_NO_OPERATORS_IN_NAMESPACE
by Daniel Frey 18 May '05

18 May '05

A new version of operators.hpp is available in the sandbox at <http://boost-sandbox.sourceforge.net/vault/index.php?&directory=daniel_frey>, it contains an improved workaround for compilers that need BOOST_NO_OPERATORS_IN_NAMESPACE. Other compilers should not be affected, but hey, you never know :) I'd like to ask for people to test the new version. In particular, the following compilers set BOOST_NO_OPERATORS_IN_NAMESPACE in their config-files (see boost/config/compiler/...) for some versions: - GCC < v3 - Borland - Digital Mars - ACC (hp_acc) If you (still) have one of these compiler with the affected versions, please test the new operators.hpp. Besides running the regression tests, which obviously must work, you can try to compile the following examples with the old and the new version: Example1.cpp: #include <boost/operators.hpp> using namespace boost; class a:addable1<a>{ public: a& operator+=(const a&){return *this;}; }; int main(){ } Example2.cpp: #include <boost/operators.hpp> bool addable1; int main(){ } Both examples previously failed to compile on (some of?) the compilers that had BOOST_NO_OPERATORS_IN_NAMESPACE defined, the new version should fix that. Also, reviews of the patch are also welcome. One final note: The new version will not go into 1.33.0, which is why I choose to put the new version in the sandbox first. Once 1.33.0 is out and given that the initial tests look positive, it will go into CVS to make sure the full regression testing is applied and the regression test will be improved to check for the above examples. Out of curiousity: Will the new version (with the appropriate define set) improve the situation for the VC7? Anyone care to check that, too? (If it shows an improvement, I honestly have no clue why ;) Thanks for you time. Regards, Daniel

Interesting. Still doesn't explain why the compiler is trying to use the intrusive stuff, rather than the non-intrusive layer, at least to my relatively unschooled C++ mind. Is there anything I should do, or should I try something like writing wrapper classes for everything? > Marcin Tustin wrote: > >> -----Original Message----- > >> From: Robert Ramey [mailto:ramey@rrsd.com] > >> Sent: 13 May 2005 15:51 > >> To: boost(a)lists.boost.org > >> Subject: [boost] Re: Non-intrusive serialization with VC2003 (7.1) > >> > >> Try putting your function inside the namespace D2 > > > > I did.
