Hello, I got hands on the Visual Studio 2010 Beta 1 and had to rebuild the 1.34.1 version of boost libraries I use in my project with the new VC 10 compiler. Thread, Test, IOStreams, Filesystem built fine, but program_options failed.
Let me first clarify why I do need 1.34.1: This is the version that is most available on Linux servers (including the one I develop for), so I need this version on my development box to ensure source code compatibility, even though this version does not officially support even VC 9 (which however builds it fine and I happily use it).
Below I list the errors that happened with the VC 10 compiler. I aggregated them to 3 issues. For multiple occurences of issue 1., I only copy/paste the full output for the first occurence.
I would welcome if someone could tell me if these are the new compiler's fault, or not. If they are, I plan to report them on MS Connect so that they can hopefully get fixed before next Beta (or at least before the RTM).
1. C2668: 'boost::bind' : ambiguous call to overloaded function
See https://svn.boost.org/trac/boost/changeset/53700
2. Deduction of template parameters for std::transform (C2780, C2784) ================================================= libs\program_options\src\parsers.cpp(73) : error C2780: '_OutTy *std::transform(_InIt1,_InIt1,_InTy (&)[_InSize],_OutTy (&)[_OutSize],_Fn2)' : expects 5 arguments - 4 provided C:\Program Files\Microsoft Visual Studio
I have no idea about this.

No idea; there are no changes in that file that might have fixed anything like that. - Volodya
