Hi,

I've finally been able to successfully compile the code (derived classes, from the documentation). The problem seems to be Visual C++ 2005 Express, because I compiled the same code in Visual Studio .NET 7, using the early luabind beta7 release candidates, and it worked perfectly.

Does anyone uses Visual C++ 2005 Express? Do you have the same problems?
Will it be possible that it doens't work because boost still does not support  this compiler?

Is there an estimate date for the release of luabind beta7?

Thanks,
Pedro Bolaños.
