me too

[szhaomsft]

me too.. why official build doesn't break?

@dataangel @BabbooKumar

here is how u can fix? install VCToolSet 14.11 using VS 2017 setup.

•Open Command Prompt
•call "%VS2017INSTALLDIR%\VC\Auxiliary\Build\vcvarsall.bat" amd64 -vcvars_ver=14.11

then devenv from the command prompt

Same problem. @szhaomsft This solution doen't work for me.

[BabbooKumar]

Hi got it resolved, what I did is took the above guidance and did the following: changed the properties of EvalWrapper project as follows: Project ->Properties -> General->Target Platform Version -> 10.0.14393.0 and also Project ->Properties -> General->Visual Studio 2015 (v140)->Visual Studio 2015 (v140) I was able to compile and build without any errors Regards

Did you try the Windows devInstall script?

[BabbooKumar]

No, I Cleaned the whole Solution and followed the iinks to install missing projects set the environments variables build them individually till there were no errors. Got Stuck with EvalWrapper followed the tip above realised that I have Visial 2017 Enterprise Edition and applied the above tip by setting the properties and was successful Regards Babboo KeDengMS <notifications@github.com> schrieb am Di., 27.

I still cannot compile EvalWrapper using VS 2017. I changed

Project ->Properties -> General->Target Platform Version from 8.1 to 10.0.14393.0
and this was already set to
Project ->Properties -> General->Visual Studio 2017 (v140)

Please make sure you have submodule multiverse by running git submodule update --init.

@KeDengMS ran git submodule update --init but that didn't help.

I am getting this issue as well. I believe I have all other environmental prerequisites installed properly (via the Powershell script mentioned above). When inspecting the General preferences for the EvalWrapper project I see only one option each for Windows SDK Version and Platform Toolset (10.0.16299.0 and Visual Studio 2017 (v141) respectively).

The compiler error does not appear to be coming from anything within EvalWrapper itself, but rather from the externally referenced standard MSVC library, a file type_traits. Originally I had VC++ 2017 version 15.4 v14.11 toolset installed as recommended at https://docs.microsoft.com/en-us/cognitive-toolkit/setup-cntk-on-windows. I've also tried installing the newer versions available (15.5 v14.12, 15.6 v14.13, and 15.7 v14.14) with the same error.

The compile is specifically failing at:

	// STRUCT TEMPLATE is_convertible
template<class _From,
	class _To>
	struct is_convertible
		: bool_constant<__is_convertible_to(_From, _To)> //<-- Failure Here
	{	// determine whether _From is convertible to _To
	};

I was able to resolve this by following the instructions at: https://blogs.msdn.microsoft.com/vcblog/2017/11/15/side-by-side-minor-version-msvc-toolsets-in-visual-studio-2017/. After copying the Microsoft.VCToolsVersion.14.11.props file and then modifying the vcxproj file to force it to use the 14.11 props, EvalWrapper built successfully. I needed to repeat this process with the MathCUDA project as well.

The above solution i.e: to target the platform version works for Debug mode. However when in Release mode it changes to this error:
fatal error C1007: unrecognized flag '-Ot' in 'p2'
What am I missing here? I am attaching the full output from release build
