如何添加相对于当前文件的头文件路径? [英] How to add header files path relative to the current file?

问题描述

我在以下目录中有文件mx_minimum_power.cpp

I have the file mx_minimum_power.cpp in the following directory

D:\thesis library.Data\ALOS-PALSAR 12x2\San Francisco L 12x2  

和我要包含在以下目录中的cpp文件中的14个头文件:

and 14 header files that I want to include to the cpp file in the following directory:

D:\thesis library.Data\ALOS-PALSAR 12x2\San Francisco L 12x2\Eigen\Eigenvalues  

，因此相对于我的.cpp文件，这些.h文件的相对路径为\Eigen\Eigenvalues
我应该如何包含所有这些头文件的相对路径.
到目前为止，我已经完成了:

so the relative path to these .h files with respect to my .cpp file is \Eigen\Eigenvalues
How should I include all those header files relative path.
I've done so far:

#include <math.h>
#include <complex>
#include <iostream>
#include "mex.h"
#include "matrix.h"
#include "\Eigen\Eigenvalues"

using std::complex;
using std::cout;
using std::endl;
using namespace Eigen;

/* The gateway function */
void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[])
{
    double *arraysizePtr = NULL;
    arraysizePtr = mxGetPr(prhs[9]);
    const int arraysize = (int)*arraysizePtr;
    const int matrixDimention = 3;
}

但是当我在matlab中运行以下命令以构建.mexw64文件时:

but when I run the following command in matlab in order to build the .mexw64 file:

mex -g mx_minimum_power.cpp  

我得到了错误:

Building with 'Microsoft Visual C++ 2013 Professional'.  
Error using mex
mx_minimum_power.cpp
D:\thesis library.Data\ALOS-PALSAR 12x2\San Francisco L 12x2\mx_minimum_power.cpp(6) : fatal
error C1083: Cannot open include file: '\Eigen\Eigenvalues': No such file or directory

推荐答案

#include "Eigen/Eigenvalues/first.of.14.h"
...

然后让编译器知道查找.".作为include的基本路径，假设您从源目录运行编译器.在gcc/g ++中，使用"-I".我在MSDN上找不到等效项，但是有一个.我几年前用过.

Then let the compiler know to look in "." as a base path for includes, assuming you run the compiler from the source directory. In gcc/g++ one uses "-I.". I couldn't find the equivalent on MSDN, but there is one. I used it years ago.

这从字面上回答了您的问题，但是我会告诉编译器查找"Eigen \ Eigenvalues"，然后仅使用上面的14个名称，而不使用两个级别的目录.

That literally answers your question, but I would tell the compiler to look in "Eigen\Eigenvalues" and then just use the 14 names as above without the two levels of directories.
