Hi Ian, --- Ian Baxter <ibaxter@gmail.com> wrote:

Asio when compiled in a mixed assembly with VS 8 produces a link error (LNK2022) because of an undefined struct in error.hpp.

changing line 288 error.hpp to this: struct unspecified_bool_type_t{ };

fixes the problem.

Thanks for that, I've just checked in the fix. Cheers, Chris
