[asio][msvc-8_0] compilation failed on example
Hi, 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. 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. JD

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

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

It seems that the example has not been updated accordingly: still use !err.

Well IPV6_UNICAST_HOPS is defined in my ws2tcpip.h. I'm using WinXP SP1 SDK. And my include path is pretty simple: boost only... Thanks anyway. JD

No, it's correct. That particular use of asio::error has been replaced with boost::system::error_code, and that class supports operator!.

Unfortunately I can't tell what's going on from here, but it really looks to me like it's picking up an old ws2tcpip.h header from somewhere else. Asio includes that header from asio/detail/socket_types.hpp. Cheers, Chris

Ok, I was mixing version of asio and didn't notice the changes between the two example files.

There is two versions of this file on my system and the other one (part of cygwin) in definitely not included in my path. Moreover I was compiling the example using the Jamfile provided so... I'll dig this if I have some time and keep you posted if I found out what's going on. Thanks for your precious help. JD

Check your Project and Solutions settings as well. Tools->Options->Project and Solutions->VC++ Directories Then Show directories for include files. You may have an old version of the platform SDK listed before the newest one. HTH, --Michael Fawcett
