There are a couple of more or less complete implementations laying around: * http://tinyurl.com/2qrpq, 'rational_c' implementation by Hugo Duncan; * http://tinyurl.com/39mjl, "static_rational.hpp" by Matthias Schabel (it's a part of YANL, his dimensional analysis library). The main reason one of them is not in the library yet is that their notation for arithmetic operations leaves something to be desired -- you have to write something like rational_plus<r1,r2> instead of mpl::plus<r1,r2> Besides this issue, AFAIK these are already usable. Of course, if you would like to improve them/contribute more optimal/clean/better in any other regard implementation, please do. As for 'fixed_c', I am not aware of any publicly available implementation.

No, please go ahead! Cavalry have enough on their plates already (among other things, a new version of the library is upcoming, with plenty of new exciting and useful stuff like associative sequences), so progress on these two is totally in your hands. -- Aleksey Gurtovoy MetaCommunications Engineering

date_time formatting compilation error
by Keith MacDonald 14 Mar '04

14 Mar '04

I'm trying to convert a gregorian::date to a string, as shown in the following code: // Build: cl /EHsc /I \CVS\boost dt.cpp #include <iostream> #include <boost/date_time/gregorian/gregorian.hpp> int main() { boost::gregorian::date today(2004, boost::gregorian::Mar, 14); std::cout << today << std::endl; return 0; } When I compile it with Visual C++ 7.1, using Boost from CVS head, I get the following error: \CVS\boost\boost\lexical_cast.hpp(150) : error C2679: binary '>>' : no operator found which takes a right-hand operand of type 'boost::date_time::date_formatter <date_type,format_type,charT>::string_type' (or there is no acceptable conversion) with [ date_type=boost::gregorian::date, format_type=boost::date_time::simple_format, charT=wchar_t ] The same thing happens when using to_simple_string and to_simple_string_type<char>, rather than operator<<. I actually want the result as a basic_string<wchar_t>, but all variations produce this same error. What am I doing wrong? Thanks, Keith MacDonald

mpl rational_c and fixed_c
by Matt Calabrese 14 Mar '04

14 Mar '04

A couple of days ago I started work on a library where I need a way to represent rational numbers and fixed point precision numbers at compile time, so I started creating a compile-time rational number type following the style of integral_c in boost::mpl. After completing most operations, I notices that in the mpl/math directory there were already the beginnings of rational_c and fixed_c types, however, they are far from complete (in rational_c there are just two static constants for numerator and denominator and a self typedef, with no specialized operations). Are these types still in development or are they abandoned? I'd like to continue my project using mpl::rational_c and mpl::fixed_c as I need to make them work with the mpl integral constants anyways. So is development on these templates halted, meaning I should just go ahead and finish my types, or are the types coming soon enough so I just should just hold off and wait for the cavalry to arrive?

Could your guys see what is wrong with my following c++ extension code?
by Shunming Fang 12 Mar '04

12 Mar '04

Heollo, guys, I try to wrap a c++ extension class requiring qt lib through boost.python, I failed always because of the following error: c:\Python23\include\object.h(343): error C2059: syntax error : ';' My code will link to qt-2.30nc lib (window version). I don't know why. Can someone give ahint how to fix it? Thank you very much.

RE: [Boost-users] regex with msvc-stlport
by Jia Pu 12 Mar '04

I have seen the similar problem, when I built it using intel-win32. I would suggest you to check regex\user.hpp. There are a couple of macros need to be set for win32 dll. I am not sure what is the proper setting. Just play with it. // define this if the runtime library is a dll, and you // want BOOST_REGEX_DYN_LINK to set up dll exports/imports // with __declspec(dllexport)/__declspec(dllimport.) #define BOOST_REGEX_HAS_DLL_RUNTIME // define this if you want to dynamically link to regex, // if the runtime library is also a dll (Probably Win32 specific, // and has no effect unless BOOST_REGEX_HAS_DLL_RUNTIME is set): #define BOOST_REGEX_DYN_LINK // define this if you don't want the lib to automatically // select its link libraries: #define BOOST_REGEX_NO_LIB Hope this will help. -----Original Message----- From: boost-users-bounces(a)lists.boost.org [mailto:boost-users-bounces@lists.boost.org] On Behalf Of Juan Casanueva Sent: Friday, March 12, 2004 7:13 AM To: boost-users(a)lists.boost.org Subject: [Boost-users] regex with msvc-stlport Hi, I am trying to build de regex boost library with msvc and stlport4.6.1, with no success!!! help!!!!

What I wrote holds true for raw pointers. I had assumed it also held true for the Boost smart pointers, but as you pointed out in the other email - and I verified with a quick test - the smart pointers get around this problem.

Huh - whaddya know; I just tried it with this program: int main() { boost::shared_ptr< T > t = CreateT(); t.reset(); T * tptr = CreateRawT(); delete tptr; } where CreateT and CreateRawT are exported from a DLL (and do the obvious thing). 't.reset()' works OK, but 'delete tptr' asserts on an invalid heap pointer. I'll have to study the shared_ptr implementation to see how it avoids this problem. -- Jim Hyslop Senior Software Designer Leitch Technology International Inc.

I've been using it successfully across DLL boundaries with no problems. The biggest caveat is to ensure you are using the DLL version of the C Runtime library. If you use the static library version, then each DLL will have its own heap, and a pointer *must* be deallocated in the same DLL in which it was allocated. -- Jim Hyslop Senior Software Designer Leitch Technology International Inc.
