I am interested in using Appveyor to build C++ code that depends on C++11 features. So far I've been testing https://ci.appveyor.com/project/springmeyer/variant and have noticed compiler errors that indicate lacking support for the constexpr keyword. This is a known issue with the 2013 compiler addressed in this update: http://blogs.msdn.com/b/vcblog/archive/2013/11/18/announcing-the-vi...

Would it be possible to provide that version on appveyor instances?

    Hi Dane,

    Can that CTP be installed side-by-side with VC++ 2013. I mean does it override C++ compiler that is part of VS 2013 installation?

    I'm not sure - I've not yet started running this version locally (part of why I'm interested in using Appveyor).

    Well, I feel it is something affecting all clients, so we'd like to be sure it's going to be OK before backing it into build working images :)

    Hi Feodor and Dane,

    @Feodor No it wouldn't override the default compiler, it would be an additional compiler:
    See "Instructions" at the official Download:
    http://www.microsoft.com/en-ie/download/details.aspx?id=41151

    @Dane Probably we could include the download and install of the CTP into the build processs.
    Maybe via Web Platform Installer or manually.
    It's only 33MB.
    Although I'm not sure, if gyp is able to create a solution file that is compatible with the instructions mentioned above.

    Hi Willy,

    Thanks for your notes! This is good the update could be installed side-by-side.

    Thanks Willy. You are exactly right. Locally on Windows 7 I confirmed that the install is totally separate. And then I also confirmed that my code compiles with it, just as I hoped.

    Feodor: would it be possible to include this extra compiler toolchain by default soon? I've got a number of projects that will be moving to c++11 so this would be really nice to have.

    Btw, it is easy to ask msbuild to use this alternative compiler simply by setting a custom Platform Toolset in the project file.

    Not sure about making it a default choice, but we can install this update to build machines, so you can tweak your project file to use it.

    Exactly: I don't think it should be default. As long as it is installed users that need this toolchain can simply tweak their project file. For reference: I'm using GYP to generate visual studio projects and the only tweak I needed was this line: https://github.com/mapbox/variant/blob/20f26eceebef717a0ee759b42bfe...

    Visual studio 2014 preview with more C++11 features is now available: http://www.visualstudio.com/en-us/downloads/visual-studio-14-ctp-vs.... I'm still doing okay with the 2013 CTP update at this point, but I could see needing this in the future. For now I will close this issue however.
