Hello,<div><br></div><div>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.</div>
<div><br></div><div>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).</div>
<div><br></div><div>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.</div><div><br>
</div><div>I would welcome if someone could tell me if these are the new compiler&#39;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).</div>
