I create a simple main function and above it, I include armadillo library.
#include <armadillo>
I compiled it using g++ (version of GCC is 5.3) and under cygwin 64bit on windowse 8. I turned on c++11 option and added -larmadillo for linking to armadillo library.
Once I compile the code, I receive such horrible error. The same code runs absolutely fine on windowse XP 32 bit.

So I coding a simple tensor with Eigen as follows:
#define _USE_MATH_DEFINES
#include <iostream>
#include <cmath>
#include <Eigen/Dense>
#include <unsupported/Eigen/CXX11/Tensor>
using namespace Eigen;
using namespace std;
int main () {
Tensor<double, 3> A(4,5,6); // 3 dimensions (4x5x6)
A.setZero();
A(0,1,2) = 1.7;
A(1,2,2) = -1.5;
cout<<A(1,2,2)<<endl;
return 0;
}
But then I get the following error and I looked around the internet for help, but sadly I am still clueless. I always get this error with my more advanced code, so I decided to do a small code just to test when I get this error. Note: I didn't get this error when I was did the same with an Eigen matrix. Only when I changed to a tensor, did I get this error. Then afterwards I changed it back to a matrix and I somehow get the same error now? However, even in my more advanced code I don't even have any tensors, but for some reason still get this error. Can someone please help me as this is driving me insane?

UPDATE: When I remove the last include and do the Eigen matrix again, there's no problem. So the problem is with the last include. But without it, I can't work with tensors. What should I do to work with tensors without the error?
Can you let us know where your version of MinGW comes from?
The issue is that your version of MinGW is apparently defining __int32 as long but int32_t as int, leading to a type conflict. We had some code in the Tensor module to ensure int32_t is always defined on Windows, since Visual Studio prior to 2010 doesn't actually provide an stdint.h header. We've never seen this cause an issue before. I tried several versions of MinGW, both 32-bit and 64-bit, but in all the ones I've tried so far __int32 is always an int.
I have a potential fix pending on the master branch here: !373. Once it's merged we can backport the change to the stable 3.3 branch.
If you just want to get something up and running, you can try installing a different version of MinGW.

How do I build it with <atomic> library?
I have a bunch of code which compiles in Ubuntu using GCC 4.8.4.
When I transfer to centOS and compile it there the following errors occur:
[ 0%] Building CXX object src/chrono/CMakeFiles/ChronoEngine.dir/core/ChClassRegister.cpp.o

make[1]: *** [src/chrono/CMakeFiles/ChronoEngine.dir/all] Error 2
make: *** [all] Error 2
These errors are for both GCC 4.4.7 and GCC 4.8.5.
The lines of code for which it gives the error are:
~ChClassFactory () {
for(const auto & it : class_map ) {
GetLog() << " registered: " << it.first << "\n";
}
GetLog() << "Delete ChClassFactory \n";
}
And the files included at the top of this script are:
#include <stdio.h>
#include <string>
#include <typeinfo>
#include "core/ChLog.h"
#include "core/ChRunTimeType.h"
#include <unordered_map>
I have checked that all of the include files exists and I have made another script to test if I can use them, and I can.
The reason why I don't stay with Ubuntu is because the Supercomputer I have to use is running centOS.
Does anyone have a solution for this problem?
Please let my know if you need additional information.
Regards,
Anders
Edit
With the GCC 4.8.5 version the program provided by NathanOliver compiles and run.
I compile it directly from terminal using:
g++ -std=c++11 main.cpp -o main
./main
1 2 3 4 5
And it runs with -std=c++0x.
Somehow I cant use -std=c++14.
It gives the following error:
g++: error: unrecognized command line option '-std=c++14'
Edit
So to get back to the main problem. My Makefile I have, have the following line:
//Flags used by the compiler during all build types.
CMAKE_CXX_FLAGS:STRING=-std=c++0x
So I can't see why the program should not run?
I have just started to work with QT and am still getting familiar with the compilation process. Currently, I am trying to port an existing QT project to Mac. This app compiles and runs on Linux and Windows.
When I compile the project on Mac OSX 10.8.2 , I am getting this c++11 related error ,
#include ../xxx/pch.h:71:10: fatal error: 'atomic' file not found
#include <atomic>
^
1 error generated.
make[1]: *** [debug/xxx/objective-c++.pch] Error 1

11:32:01: The process "/usr/bin/make" exited with code 2.

When executing step 'Make'
I have included the below flags in the.pro file to enable c++11 ,
QMAKE_CXXFLAGS += -std=c++11
CONFIG += c++11
I am building the project with the pre-built QT5.1Beta package (Clang) which I believe has c++11 enabled.
I see the atomic header in the below locations
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/c++/v1/atomic
and in /usr/lib/c++/v1/atomic
I tried testing by including the complete path ,
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr//lib/c++/v1/atomic
I am getting the below error,

What am I missing here?
Add also
macx:QMAKE_CXXFLAGS += -stdlib=libc++
macx:QMAKE_LFLAGS += -stdlib=libc++
Maybe it is a bit late, but I fixed it using the -std=gnu++0x flag
