Compiling and using NTL c++ library for Windows - c++

I have compiled the NTL inifite precision integer arithmetic library for c++, using Microsoft Visual Studio 2008. I did as explained, on this site, using the Visual Studio interface, rather than from the command prompt. Actually I would rather do it from the command prompt, but I was not sure how to.
Anyhow, I got the library compiled, and I now want to compile a program using the library, from the command prompt. The program I am trying to compile, has been tested on a linux system, where I compile it with the following
c++ -I/appl/htopopt/Linux_x86_64/NTL-5.4.2/include mpqs.cpp main.cpp -o main -L/appl/htopopt/Linux_x86_64/NTL-5.4.2/lib -lntl -L/appl/htopopt/Linux_x86_64/gmp-4.2.1/lib -lgmp -lm
Nevermind the gmp stuff, I dont have that installed on Windows. It is purely an optional thing that will make the NTL run faster. Anyhow, this works fine on linux. Now on Windows I write the following
cl /EHsc /I D:\Downloads\WinNTL-5_5_2\include mpqs.cpp main.cpp /link /LIBPATH:"D:\Documents\Visual Studio 2008\Projects\ntl\Debug"
But this results in the following errors:
mpqs.cpp
mpqs.cpp(38) : error C2039: 'find_smooth_vals' : is not a member of 'QS'

It is as if, my mpqs.h file is not included into the compilation process? Also I dont understand why it complains about .push_back() for a vector type?
Help is much appreciated!

mpqs.h is definitely being included as the output asks you to refer to it.
Seeing as MPQS.h does not appear to be included in the NTL library ... did you write it? If so can you post the code up?
Also, shouldn't you included the library file somewhere on your build?
Edit: There is no function find_smooth_values so why should you expect MSVC to find it? I'm not sure why that compiles under GCC but its obviously missing. I'm guessing that the other errors are caused because of this one. The errors are telling you things. You should listen to them.
push_back is failing because it doesn't know what the type you are trying to push_back into is. This again is probably caused by the fact that find_smooth_values doesn't exist. Try adding the function prototype into the QS class. This may well fix all your problems.
As for the library it won't get to using the library until the compilation succeeds. So don't worry about that just now. Get in there and fix the errors that MSVC is reporting!

Using vcpkg and compiling in Visual Studio 2015

I am trying to compile (by porting) some code in Windows 10 that was originally developed for Linux.
The code depends on 2 external libraries: cppkafka and librdkafka.
I saw that vcpkg is able to get the libraries, compile them, and then make them automatically available in Visual Studio 2015 (through the vcpkg integrate install command).
I see that the vcpkg compiles the dependencies for windows 64 (cppkafka and librdkafka) properly, as the .dll, .lib... are all made available on the install folder of vcpkg.
When I try compiling my code in Visual Studio 2015, I see errors concerning the dependencies headers, which for me is unexpected. If vcpkg compiled them, why Visual Studio doesn't? From the vcpkg documentation, I assume they use the same compiler. Next I show some example errors I am getting:

Why is my code not compiling when including OpenCV in my Visual Studio Project?

There is too much code to post so I'll be short and sweet here.
I'm migrating a project to Visual Studio that I originally built in Eclipse on OSX, using the OpenCV Apple framework distribution (opencv delivered as a .framework).
I've created a visual studio project from the existing code but when I build it, I get a bunch of errors from one of the headers (opencv2/core/fast_math.hpp) that are included along the header chain of <opencv2/opencv.hpp>.
1>c:\users\blah\tools\lib\opencv\build\include\opencv2\core\fast_math.hpp(105):
error C2065: '__m128d': undeclared identifier
1>c:\users\blah\tools\lib\opencv\build\include\opencv2\core\fast_math.hpp(105):
error C2146: syntax error: missing ';' before identifier 't'
1>c:\users\blah\tools\lib\opencv\build\include\opencv2\core\fast_math.hpp(105):

1>c:\users\blah\tools\lib\opencv\build\include\opencv2\core\fast_math.hpp(106):
error C2065: 't': undeclared identifier
Nothing has really changed in my code, just that I'm now using Visual Studio 2017. I have added opencv\build\include to my include path. I see that this code is SIMD intrinsics, which I don't think should have any problem compiling.
Is there a step I'm missing here?
This looks to be something with how I set up the project. The SIMD intrinsics require extra headers. I didn't configure the project to use precompiled headers which also appears to explain why std::string was undefined too. The extra headers can be added in stdafx.h and it's presence resolves other missing components.

Boost C++ libraries generating strange errors

I recently tried to write a c++ program, where I used the build in socket tools you can find in the Boost library. First of all, I tried to make a client/server based program, where the server just sends a message and the client receives it. It worked just fine.
Then I wrote another program, where I used a Xbox 360 kinect, to control my movement. The idea of creating the first program, was the get the code for the socket creating, so I can connect with, i.e. my Samsung tv, to control the tv, using my kinect.
The problem arises, when I copy my code from the first program, into my second program with the kinect. All of sudden, the program gives 100+ error, when compiling the boost library.
I triple checked the including libraries and all, but the problem still arises. Some of the errors are posted below:
1>C:\boost_1_55_0b1\boost/asio/detail/socket_types.hpp(96): error C2143: syntax error : missing ';' before '.'

And many many others. I know by the fact, that the libraries work. It worked in the first program, so I just can't figure out what's causing the problem.
Other includes are the SDL and SDK for Kinect libraries for c++.
I just came across this too. I found by adding the "/P" option to the C++ compiler options in Visual Studio and recompiling the file that failed, that s_addr was indeed getting #defined.
The offending header was part of the Windows SDK inaddr.h, which is included in the header chain of winsock.h.
The offending line in the header was:
#define s_addr S_un.S_addr
More information about this header is on MSDN here.
The fix I found was to #undef s_addr just before the #include of the BOOST ASIO header.

Winbase.h doesn't support in creating DLL file

I would like to create a project use to call c++ method using c#. So, I need to create a dll file for all of my c++ function. But when i get an error in y sqlite source code such as "AreFileApisASNSI undeclared identifier". So, i import winbase.h which is part of the mingw-w64 runtime package to my visual studio 2012 express DLL project. After import the file, I get many errors such as below:-
error c4430: missing type specifier - int assumed. Note: C++ does not support default - int
error C2143: syntax error : missing ';' before '_stdcall'
error c1003 error count exceeds 100; stopping compilation
error c2061: syntax error: identifier ' WINBOOL'
error c2086: 'int_CRT_INLINE' : redefinition
error c2143: syntax error: missing ';' before ''
error C2146: syntax error : missing ';' before identifier 'LONGLONG'
error C2146: syntax error : missing ';' before identifier 'PVOID'
any solution for those error? please help!!
The documentation for the function has this header requirement:
WinBase.h (include Windows.h)
This is telling you that the function is declared in WinBase.h, but that you should include Windows.h which in turn will include WinBase.h. So, you need to change your include to
#include <Windows.h>
I also wonder why you are talking about mingw considering that your compiler is MSVC. That compiler ships with a comprehensive Windows SDK. Why would you be using an SDK from mingw?

error C2065: 'errno' : undeclared identifier in <string> in Visual Studio 2012

I had a project running in Visual Studio 2010. Now I am using Visual Studio 2012.
Now I am getting below error while building the project.
I have looked into Google and SO as well. But no where I got any solution.
c:\program files\microsoft visual studio 11.0\vc\include\string(557): error C2065: 'errno' : undeclared identifier

2>c:\program files\microsoft visual studio 11.0\vc\include\string(579): error C2065: 'errno' : undeclared identifier
I have tried with including stdlib.h into the sting header file but still I am getting this same error.
Any help appreciated.
There could be several possible reasons for this problem. The
first thing you should do is to create a one line source:
#include <string>
and nothing else, and try to compile it. If this doesn't
compile, there is a problem with your installation, and you
should reinstall it. Then, just to be sure, delete everything
in your source tree except the actual sources, project files and
solution, and rebuild. There may be some old files laying
around which are somehow causing the problem. I doubt it, but
this is something you should do anyway, any time you upgrade
a compiler, or even just install a patch. (If you've got
everything under source code control, which you should, the
simplest solution is just to delete everything, and do a new,
clean checkout.)
If these measures don't solve the problem (and somehow,
I suspect they won't), there's a problem in your code base
somewhere. errno is required to be a macro by the standard;
to get the error message you cite, the macro must be undefined.
<string> includes (indirectly) a file which defines it. Given
this, the only cause I can think of is that an earlier include
file has already included a file which defines errno, and then
#undefed it. To verify this, put your #include <string> as
the very first include of your source, and see if this solves
the problem. If it does, then you have to find the file which
does the #undef, and fix it.
I had the same issue. Strangely enough, the problem was not including "using namespace std;" under the header file includes. Apparently, program would recognize "string" unless I did this, even though "char", "float", etc were recognized.
