hi list can any one send me REDHAT rpm of boost jam. thanks

Thanks for your response. I get the same results whatever I try, including with testgreg_wstream.cpp. The only way I've been able to get my code working is to define BOOST_DATE_TIME_NO_WSTRING_CONVERSIONS, and then convert to wchar_t myself. I'm pretty sure my CVS files are up to date, but here's a directory listing (in dd/mm/yyyy format), just in case: 18/02/2004 17:49 5,731 formatters.hpp 15/02/2004 16:17 2,845 formatters_limited.hpp 18/02/2004 17:49 1,006 gregorian.hpp 02/12/2003 15:14 3,107 gregorian_types.hpp 02/12/2003 15:14 1,572 greg_calendar.hpp 12/01/2004 16:42 3,824 greg_date.hpp 02/12/2003 15:14 1,826 greg_day.hpp 02/12/2003 15:14 1,078 greg_day_of_year.hpp 02/12/2003 15:14 922 greg_duration.hpp 01/03/2004 16:58 8,288 greg_facet.hpp 18/02/2004 17:49 2,911 greg_month.hpp 18/02/2004 17:49 1,897 greg_weekday.hpp 02/12/2003 15:14 1,648 greg_year.hpp 02/12/2003 15:14 904 greg_ymd.hpp 01/03/2004 16:58 3,195 parsers.hpp - Keith MacDonald "Jeff Garland" wrote in message news:20040314143154.M74344@crystalclearsoftware.com...

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 int main() { boost::gregorian::date today(2004, boost::gregorian::Mar, 14);

std::cout << today << std::endl; return 0; }

This definately should work. What happens if you do std::cout << to_simple_string(today) << std::endl; or std::wcout << to_simple_wstring(today) << std::endl;

...

When I compile it with Visual C++ 7.1, using Boost from CVS head,

Are you positive about this? Changes to support wide streaming went in a couple weeks back. Seems like maybe you don't have all of that change.

...

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 ::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, but all variations produce this same error. What am I doing wrong?

I really don't know. Can you try running the regression tests in your environment? In particular I'm interested in

libs/date_time/test/gregorian/testgreg_wstream.cpp

Anyway, judging from the regression tests this should be working for you...

I've definitely only got VC7.1 on my PC, so that's not the issue. As to the regression tests, I was not familiar with how to build and run them, so I simply tried to compile testgreg_wstream.cpp on its own, using "cl /EHsc /I \CVS\boost". As it failed to compile, there was no question of getting NO_WSTRING conversions. Having just read up on how to run the regression tests, I've successfully built and run those for date_time, so there must be something simple wrong with my compiler options. What else do I need, apart from "cl /EHsc /I \CVS\boost" -which is sufficient for the regex library?

I'll check the CVS dates in a bit, but this leads me to believe you aren't actually using VC7.1? Is that somehow possible? The only other conclusion would be that the regression tests are somehow getting NO_WSTRING conversions set when they are run...

Just include after your wxwidgets include and before the boost::date one. Let me know if it works :) George Diamantopoulos Keith MacDonald wrote:

OK, I've found the missing compiler option: /Zc:wchar_t (treat wchar_t as a built-in type), in vc7.1-tools.jam in tools\build\v1. However, as that option breaks the wxWidgets library, I cannot use it. Can the date_time library be made to also work when wchar_t is a typedef to unsigned short?

Thanks, Keith MacDonald

wchar_t is defined in that file as typedef unsigned short wchar_t; Did you compile your wxwidgets using /Zc:wchar_t? If so, try disabling that and including wctype.h instead. George Diamantopoulos Keith MacDonald wrote:

Thanks for the suggestion. The problem is that I'm statically linking to a Unicode build of wxWidets, so I get unresolved external symbols such as:

"wchar_t const * const wxDialogNameStr" "wchar_t const * const wxButtonNameStr" "public: static void __cdecl wxObject::operator delete(void *,wchar_t const *,int)" "public: wchar_t const * __thiscall wxLocale::GetString(wchar_t const *,wchar_t const *)const"

I'll have to figure out how to build wxWidgets with /Zc:wchar_t
