OMG, i'm so blind...... I messed up 12d and 15d, maybe those should get =
other names ;o) now it's all clear why it can't work....

Anyway thanks for your time, and sorry for messing around in here!

Cheers, Markus=20

Betreff: AW: boost ?!

Hm, the struct thing was completely wrong, sorry....

Ok, i just digged a little into this:

For example one of the unresolved symbols is:

__imp_?begin@?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@=
@QAEPADXZ=20

Which would be:

__declspec(dllimport) public: char * __thiscall =
std::basic_string<char,struct std::char_traits<char>,class =
std::allocator<char> >::begin(void)

The Stdcxx library has symbols some symbols which are close:

__imp_?begin@?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@=
@QAE?AV?$__rw_debug_iter@V?$basic_string@DU?$char_traits@D@std@@V?$alloca=
tor@D@2@@std@@PADPAD@__rw@@XZ

Which would be:

__imp_public: class __rw::__rw_debug_iter<class =
std::basic_string<char,struct std::char_traits<char>,class =
std::allocator<char> >,char *,char *> __thiscall =
std::basic_string<char,struct std::char_traits<char>,class =
std::allocator<char> >::begin(void)

I now think that somehow there is a problem with the headers thinking =
they need to compile debug iterators (in build 15d!?) and when using the =
lib, they think something else ;o// i looked at my config.h but there =
was nothing i could see in there. I attached it, maybe you can see =
something.

Cheers, Markus

The difference between 15d and 15D is that the first is a 32-bit build =
type (ILP32) while the second is a 64-bit or wide one (LLP64 on =
Windows). The "wide" has nothing to do with wchar_t, it refers to the =
width of the data type(s).

Stdcxx has full support for wchar_t as long as the compiler supports it. =
Keep in mind that the MSVC /Zc:wchar_t option changes the type and =
mangling of wchar_t and thus is a binary incompatible option.
Programs that link with the library must be compiled with same setting =
of the option as the library (i.e., both on or both off).

Stdcxx is much less promiscuous (i.e., a lot cleaner) than other =
implementations of the C++ standard library when it comes to its headers =
introducing unnecessary names into scope. std::hex and other =
manipulators are required to be declared in the header <ios> and nowhere =
else so in order to use them you must include that header.
