No, you misunderstood. I _did_ build with consistent wchar_t option (off in that case). But boost won't build the date time library without native wchar_t. I tried with and without stdcxx library on windows with vc7.1, it never worked. I needed to turn wchar_t on for it to work (with <native-wchar_t> or so....), there seems to be kind of a boost bug ;o) but i'm not sure about that. On vs8 this is not a problem, since wchar_t is native by default. On vc7.1 i don't want to rebuild everything, better: i don't want to change our build mechanisms, since those are many, and not too easy to change ;o) Cheers, Markus -----Original Message----- From: boost-bounces@lists.boost.org [mailto:boost-bounces@lists.boost.org] On Behalf Of John Maddock Sent: Monday, September 25, 2006 11:02 AM To: boost@lists.boost.org Subject: Re: [boost] Windows and apache stdcxx Duft Markus wrote:

Hey!

The thing is, that the stdcxx reall should behave as if it was part of

the compiler, since it's integrated into my wgcc program, so nobody should have to do anything special to use it (no need to define or include anything, it just replaces the MS libc++) The thing is, that i

allready got really far with a little patching ;o) the only thing is, that date_time wouldn't build, because of some weird errors in lexical_cast.hpp where some operators are not found. This has to do with not useing /Zc:wchar_t. I don't understand why this breaks compilation, but i didn't want to compile stdcxx with Zc:wchar_t. Since we have an automated build system it would be a great deal of work to change the wchar_t behaviour in all builds. But at the moment i disabled stdcxx, because it didn't work out that good, so we're now waiting for things to get better ;o)

Oh right, if you build the std lib without /Zc:wchar_t and build boost with it, then that absolutely will lead to linker errors at the very least. Try building with consistent /Zc:wchar_t options and that should fix things (hopefully!).
