Deleted functions</div><div><br></div><div>None of those items are supported in VS2012, and we would like to expand their use to the rest of WebKit. Clang and GCC already support these features, so VS2012 (and earlier) hold the rest of the project back.</div><div><br></div><div>-Brent</div><div><br></div><div><br><div><div>On Dec 6, 2013, at 4:05 PM, Alex Christensen <<a href="mailto:alex.christensen@flexsim.com">alex.christensen@flexsim.com</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div dir="ltr">Is there any advantage of VS2013 instead of VS2012?

Unfortunately, this effort has been hampered by the small subset of C++11 features available in Visual Studio 2010.</div>
<div><br></div><div>You can get a feel for the level of C++11 support in the last few versions of Visual Studio here:</div><div><span style="white-space:pre-wrap"> </span><a href="http://msdn.microsoft.com/en-us/library/vstudio/hh567368.aspx" target="_blank">http://msdn.microsoft.com/en-us/library/vstudio/hh567368.aspx</a></div>
<div><br></div><div>With Visual Studio 2013, we finally have access to a compiler that supports the major C++11 features we need. Consequently, we intend to switch to VS2013 and begin taking advantage of these new language constructs.</div>
<div><br></div><div>Over the next week we will be landed a series of source changes that allow WebKit to be built with VS2013, but will continue to build with VS2010 on our build machines. Next Friday, we plan to land project file changes to switch to the new compiler, and will simultaneously convert our build system to use VS2013 as well.</div>
<div><br></div><div>Once the revised project files are landed, we will no longer be officially supporting Visual Studio 2010 as a compiler target.</div><div><br></div><div>For those playing at home, you can track progress by following <a href="https://bugs.webkit.org/show_bug.cgi?id=125192" target="_blank">https://bugs.webkit.org/show_bug.cgi?id=125192</a>.</div>
<div><br></div><div>WebKit continues to build with the free “Visual Studio 2013 Express” software, so I do not anticipate that this change will block any external developers from running Windows builds.</div><div><br></div>
