[boost] Re: Linker errors with basic_string

Hi Andreas,

Not sure this problem has something to do with Boost (if it has at all, 
I believe it's something for the boost.user list).

I cannot tell you what exactly goes wrong, due to the lack of 
information (verbose linker output, command line of invocation).

The right C++ standard library isn't loaded by the linker.

This can have the following reasons:

- You are linking the program (or your static library) with a static 
runtime library but a library you are using does want to link with a 
dynamic one (the __imp prefix indicates a missing import library). In 
this case make sure to set the right runtime-linkage while building boost.

- You are invoking the linker with NODEFAULTLIB(S) options or 
NODEFAULTLIB options have been toasted into a static library you are 
trying to use (via #pragma). I can't imagine boost developers doing 
things like this -  but I've met (non-boost) libraries with the "little 
bit of extra-horror" inside ;-).

- The default calling convention used by the standard library differs 
from the one used to build the program (or your static library), so the 
inlined code tries to call a routine which is not there. However, 
'__cdecl' looks OK, unless you recompiled your standard C++ library.

(I might have forgotten something.)

Verbose linking is a good idea to track down the problem.

Greetings,

Tobias
