它采用odeint从boost Canot编译C ++ [英] Canot compile C++ which uses odeint from boost

问题描述

我在Ubuntu 12.04和放大器;有一些外商投资企业提振已经在/ usr / include目录。我做了一个

I'm on Ubuntu 12.04 & had some boost fies already in /usr/include. I did a

sudo apt-get install libboost-all-dev

和安装大量的文件了。我不想删除此升压和其他几个包依赖于从Ubuntu软件库的版本从源代码安装。这是样板code我想运行： -

and that installed a lot of files too. I don't want to remove this boost and install from source as several other packages depend on the version from the ubuntu repos. This is the sample code I want to run :-

#include <iostream>
#include <boost/numeric/odeint.hpp>



using namespace std;
using namespace boost::numeric::odeint;

typedef vector< double > state_type;

const double sigma = 10.0;
const double R = 28.0;
const double b = 8.0 / 3.0;

void lorenz( state_type &x , state_type &dxdt , double t )
{
    dxdt[0] = sigma * ( x[1] - x[0] );
    dxdt[1] = R * x[0] - x[1] - x[0] * x[2];
    dxdt[2] = x[0]*x[1] - b * x[2];
}

int main()
{
    const double dt = 0.01;

    state_type x(3);
    x[0] = 1.0 ;
    x[1] = 0.0 ;
    x[2] = 0.0;
    stepper_euler< state_type > stepper;
    stepper.adjust_size( x );

    double t = 0.0;
    for( size_t oi=0 ; oi<10000 ; ++oi,t+=dt )
    {
        stepper.do_step( lorenz , x , t , dt );
        cout << x[0] << " " << x[1] << " " << x[2] << endl;
    }
}

在第一编译 G ++ -o测试TEST.CPP ，它抛出一个错误
/usr/include/boost/numeric/odeint.hpp权限被拒绝

ON first compile g++ -o test test.cpp, it threw an error /usr/include/boost/numeric/odeint.hpp permission denied

于是我改变了递归使用所有odeint文件的文件许可权

So I changed the file permission of all odeint files recursively using

sudo chmod -R +x odeint/

这时候，它并没有说拒绝的权限，但扔了400线的错误，因为在这里可以看到 - > 错误从终端日志

This time, it did not say permission denied but threw 400 lines of error as can be seen here -> error log from terminal

我如何编译它？还有在文档中的odeint没有安装指南或其他地方

How do I compile it ? There are no install guides for odeint in the documentation or anywhere else

推荐答案

升压的这部分似乎使用C ++ 11的特性。因此，您需要为 -std =的C ++ 0x 或 -std = C ++ 11 添加到您的编译器调用。

This part of boost seems to use C++11 features. Therefore you need to add either -std=c++0x or -std=c++11 to your compiler invocation.

随后的误差 TEST.CPP：在函数'廉政的main（）'：TEST.CPP：30：5：错误：stepper_euler没有在这个范围内声明您指向错误的另一个来源：你忘了，包括在 stepper_euler 声明文件。把合适的的#include＆LT;文件＆gt; 你的code的开始

The subsequent error test.cpp: In function ‘int main()’: test.cpp:30:5: error: ‘stepper_euler’ was not declared in this scope points you to another source of error: You forgot to include the file in which stepper_euler is declared. Put the appropriate #include <file> at the beginning of your code.
