I have found many posts about this error but I could find how to overcome it.
This is the code where the error is triggered:
void main(){
float f{1.3};
}
Why in the initialize-list no casting happened like any other variable? For example, this works smoothly:
float f = 1.3;

You’ve commented that the use of 1.3 gives an error with your compiler. That means you’ve found a compiler bug. The standard is quite clear that this is not a narrowing conversion, so it should be allowed.
Quoting N4140 (roughly C++14):
8.5.4 List-initialization [dcl.init.list]
7 A narrowing conversion is an implicit conversion
[…]
— (7.2) from
long doubletodoubleorfloat, or fromdoubletofloat, except where the source is a constant expression and the actual value after conversion is within the range of values that can be represented
(even if it cannot be represented exactly), or[…]
Your 1.3 is a constant expression well within the range of float.
I recommend reporting this to Microsoft, assuming it isn’t a known issue already. Unfortunately, simply upgrading your Visual Studio won’t fix this. I can reproduce the problem in VS2015.

Forcing it to be float using the ‘f’ suffix avoids the narrowing conversion. the below works ..
float f{1.3f}
But i agree that the compiler should have taken care of it .. (as per the standard quoted by @hvd)

Since it is C++, don’t use c-style casts, try:
static_cast<float>(std::abs(...))

This is maybe a bug or something. Use this instead:
float f;
f=1.3;

my environment is：

I followed the README.md instructions exactly and installed steps 1-6 successfully. Error in step 7.
can you tell me what to do？
I still get errors using https://github.com/3a1b2c3/kaolin-wisp-Windows. What I’m trying to say is that once I run ‘python setup.py develop’ I get the same error, either https://github.com/NVIDIAGameWorks/kaolin or https://github.com/3a1b2c3/kaolin-wisp -Windows.
Is there any workaround?

When I «pip install ninja», the above error is no longer reported, and everything is back on track. The problem encountered after that is very similar to the one described in this link. I can’t compile all the .obj’s. I believe if I’m on ubuntu maybe I can configure it successfully, but I only want to use it on windows. Is there any solution?
Hi @zh-en520 , can you post the full logs? I can’t see the FAIL from what you provided. Have you been able to build Kaolin on your system?
@Caenorst thank you for reading.
No, I can`t build Kaolin and build Kaolin-wisp.

Ok let’s start with Kaolin first, do you mind opening a new issue on Kaolin repo for reference for other users? 
Does this still fail with the new merged PR (#28)?
Closing this issue, feel free to reopen if needed
Вы отметили, что использование 1.3 приводит к ошибке с вашим компилятором. Это означает, что вы обнаружили ошибку компилятора. Стандарт совершенно ясен, что это не сужение конверсии, поэтому оно должно быть разрешено.
Цитата N4140 (примерно С++ 14):
8.5.4 List-initialization [dcl.init.list]
7 Сужение преобразования является неявным преобразованием
[…]
— (7.2) от
long doubleдоdoubleилиfloat, или отdoubleдоfloat, , за исключением случаев, когда источником является постоянное выражение, а фактическое значение после преобразования находится внутри диапазон значений, которые могут быть представлены(даже если он не может быть представлен точно), или[…]
Ваш 1.3 является постоянным выражением в пределах диапазона float.
Я рекомендую сообщить об этом Microsoft, предположив, что это уже не известная проблема. К сожалению, просто обновление вашей Visual Studio не устранит этого. Я могу воспроизвести проблему в VS2015.
I’m seeing a MIDL2398 error every time I try to compile a Visual C++ (Visual Studio 2010) project which uses COM. This project builds perfectly fine on my Windows 7 developer machine and on a Windows Server 2008 build machine, but not on a Windows Server 2012
build machine.
I found this web site about the various MIDL compiler errors:http://blog.yezhucn.com/midl/compiler_errors.htm (also
referenced yours: http://msdn.microsoft.com/en-us/library/aa367085%28VS.85%29.aspx)
But, I tried it’s suggestion for MIDL2398, I verified that «midlc.exe» was in the same directory as «midl.exe» and that both were the same version (both are file version: 7.0.555.1 product version: 6.1.7600.16385, from the Windows SDK v7.1).
I’m guessing it has something to do with Windows Server 2012, but I don’t know.
I’ve tried installing the Win8 SDK on the Win2012 server and VS2010 won’t even recognize its there. Attempted to get VS2010 to recognize Win8 SDK by following these instructions to no avail: http://blogs.msdn.com/b/vcblog/archive/2012/03/25/10287354.aspx
Has anyone been able to get the Windows SDK v7.1 (or SDK8) MIDL compiler to work on Windows Server 2012? Or, does anyone know of what else might be causing MIDL2398?
