[serialization] codecvt_null.cpp not present in windows dlls
Something odd seems to be happening on the Windows platform for the serialization library, in CVS HEAD. All the text based wide-char dynamic library tests are failing as the two functions defined in codecvt_null.cpp are not found by the linkers. I've had a quick play around with the jam files but still don't understand process/library well enough to find a fix (or even casuse of the problem) -- AlisdairM

It appears that the do_out and do_in functions in codecvt_null.cpp are not marked to be exported to the DLL (with the __declspec(dllexport) attribute). I didn't look into how this came to be broken, but the attached patch seems to fix the problem on my machine. -Dave
The patch did not work for me. I am trying to work out why the narrow character versions work with dynamic linking, but the wide character versions do not. I guess it is possible all references to these functions are encapsulated inside the narrow char dll itself, so export is not necessary to pass its own tests (and so bad declarations are not exposed) AlisdairM David Deakins wrote:
