Re: [Boost-users] [asio][msvc-8_0] compilation failed on example

I've been trying to use Boost.Asio in a project and compilation failed with VC 8.0. Compiler complains that unary operator! that should be member of asio::error is not defined.

The error handling classes have changed. See this post: http://article.gmane.org/gmane.comp.lib.boost.devel/150573

I tried to compile lib/asio/example/http/client/ from CVS HEAD and got another compile issue:

..\..\..\..\..\boost/asio/ip/unicast.hpp(62) : error C2065: 'IPV6_UNICAST_HOPS': undeclared identifier

Is there known compile issue with asio? Thanks for your help.

It sounds like you have a very old platform sdk or something on your include path. This should be defined for you in ws2tcpip.h. Cheers, Chris
