I am trying to build Google glog library on windows using Visual Studio 2015. After adding #include to get around the std::min problem on Windows, I get to 2 main errors (1 repeats a few times) below.

Seems to be an issue with the compiler generated move function, but explicitly deleting it does not work either.
LogMessage(const LogMessage&&) = delete;
Any ideas?
Cheers, Mike
The generated function is not LogMessage(const LogMessage&&) = delete;
but it is:
LogStream::LogStream(google::LogMessage::LogStream &&).
Internaly it will try to call the copy constructor of LogStream and hence the ostream which is marked as deleted.
Solution:
declare inside LogStream class:
LogStream(const LogStream&) = delete;
LogStream& operator=(const LogStream&) = delete;;
Cheers

My project needs to use both Micorsoft Visual C++ math.h and Intel MKL math.h.
Building with verbose details, I get:

The "'HUGE_VALF' : macro redefinition" message is the one that made me be suspicious.
At first I just disabled that warning, but considering that this option would only mask a potential problem, I am looking for an alternative solution.
From lines 1 and 2, you can see that Visual Studio's cmath does not include Visual Studio's math.h, as it should, but MKL's file with the same name.
How can I set my CMakeLists.txt file so that the compiler can pick the right include files?
Just wrap one library.
For example, create header file:
#pragma once
namespace imath {
double sin(double a);
}
And in cpp
#include "Wrapper.h"
#include <intel/math.h>
namespace imath {
double sin(double a) {
return ::sin(a);
}
}
Do this for every symbol you need to use in common source.
And do not include C version of math.h you are using C++ so #include <cmath>.
I am a beginner c++ programmer, and have recently upgraded to windows 10 and installed the new Visual Studio 2015. However whenever I use iostream
#include <iostream>
and attempt to compile the code, it returns 289 Errors. From my understanding cmath, and math.h are conflicting with re definitions. Here is the entirety of the code in my program:
#include <iostream>
int main() {
return(0);
}
And when this is run, the output from Visual Studio 2015 is:

I would appreciate if anyone had suggestions for how to resolve this problem.
Thanks for any help.
Your toolchain is completely broken. I suggest removing then re-installing Visual Studio.
I successfully complied this project under the platform of visual studio 2010,but in vs 2013 has occured these errors:

I want to know why there is such a difference,and how to solve it ?
why there is such a difference about VS2010 and VS2013 ? Because VS2010 doesn't have define of "cbrt",but Vs2013 have.So you can use _MSC_VER , or directly comment repeat function body in Vec.h.
I'm trying to recompile application, that compiles fine with warning level 4 in visual studio 2005 and visual studio 2008.
Since the errors (look below) are coming from std:tr1, I'm thinking there's some conflict, but not sure how to fix. My first thought was to remove all references to boost, such as but then I get an error that it can't find format method.
So here's one of the errors: (not sure what it means)
Any ideas, suggestions, solutions?
Thanks!
EDIT: Right at the beginning I see a message: Unknown compiler version - please run the configure tests and report the results
EDIT2: Piece of code that I think causes this error: (changed to protect the innocent)
EDIT3: I updated the error message, i.e added more..however I get many more error messages such as this one..so there's a bigger problem/issue.

the problem is with visual studio 2010, or I should say that with additional templates that were added to visual studio 2010 tr1, so, std::make_pair, doesn't always work. changed to pair<> and all errors magically went away.
so, if you have template problems in VC2010 and using std:make_pair, change it to pair<> and specify template parameters.
It sounds like Visual Studio might be doing something you don't know. I think you can use the Microsoft compiler with the code::blocks IDE. You can try each compiler (VS 2005/2008/2010). Also, try a diff from your source code repository to be sure Microsoft didn't "prettify" your code.
Note: You don't have to use Code::Blocks after you figure out the problem. It just might be a good tool for this particular issue.
I am having some trouble converting an old project from VS6 to VS2005. At one place in the code it uses the type variant_t so it includes comdef.h for this purpose. comdef.h then includes comutil.h which generates these errors for me:
c:\program files\microsoft visual studio 8\vc\include\comutil.h(978) : error C2535: '_variant_t::_variant_t(int) throw()' : member function already defined or declared

There is probably some configuration that is incorrect, some define missing or some include file I should have included but I can't seem to find the problem. Any pointers in the right direction is much appreciated
This looks like one of two things, an include order problem or as you stated something not getting defined but I am leaning towards the first one. You might want to check msdn and make sure there are no restrictions on when comutil.h can be included (I know this is an issue if you include winsock2.h before windows.h). There is also an option under C/C++ > Advanced to Show Includes (/showIncludes option from the command-line) which is generally helpful when trying to track issues like this down.
Does your own code do something like this:
#define long int
