win10 + vs code + MinGW + Cmake 配置

vscode 编译任务 （tasks.json）如下：

{
	// 这里配置了三个Task
    "tasks": [
    	// Task 1：生成build文件夹
        {
            "type": "shell", // 这里决定了task的类型，shell类型就是在命令行里运行command的命令，还有一种类型是“process”，这里就不介绍了
            "label": "mk_build", // task的名字
            "command": "mkdir", // 需要被运行的命令
            "args": ["build"], // 传递给command的参数
            "options": {
                "cwd": "${workspaceFolder}",
            },
        },
        // Task 2：运行cmake
        {
            "type": "shell",
            "label": "cmake",
            "command": "cmake",
            "args": [
                "-G",
                "MinGW Makefiles", // 这里必须定义生成器，否则默认cmake生成的是VS Studio可编译的工程
                "${workspaceFolder}"
            ],
            "options": {
                "cwd": "${workspaceFolder}/build", // 工作路径，就是说cmake的输出都会放在${workspaceFolder}/build文件夹下
            },
            "problemMatcher": [],
            "group": {
                "kind": "build",
                "isDefault": true
            }
        },
        // Task 3：运行make
        {
            "type": "shell",
            "label": "build",
            "command": "mingw32-make",
            "args": ["-j4"],
            "options": {
                "cwd": "${workspaceFolder}/build",
            },
            "problemMatcher": [],
            "group": {
                "kind": "build", // 这里说明这个任务时输入"build"类型的，也就是说明，这是一个生成任务
                "isDefault": true
            },
            "dependsOn": [
                "cmake" // 这里设置，说明了这个任务一定要在Task “cmake”执行之后方可执行
            ]
        }
    ],
    "version": "2.0.0"
}

　　

vs code 调试设置（launch.json）：

{
    "version": "0.2.0",
    "configurations": [
    	// Debug 1，这里也可以配置多个Debug任务，这其实和tasks.json很类似
        {
            "name": "first_exe", // Debug任务名
            "type": "cppdbg", // 类型
            "request": "launch",
            "program": "${workspaceFolder}/build/cmake_test_project.exe", // 需要调试的应用程序，这是需要按照你的需要进行调整的
            "args": [], // 传递参数给应用程序
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}", // 当前工作路径
            "environment": [{"name": "PATH","value": "${PATH};C:\\Program Files\\mingw-w64\\x86_64-8.1.0-win32-seh-rt_v6-rev0\\mingw64\\bin;D:/software/aruco/bin"}], // 这里需要特别注意，这里要把应用程序运行需要的动态链接库的路径，放进来，这里也需要你根据自己需要进行调整，我在这里给出一个示范
            "externalConsole": false,
            "MIMode": "gdb",
            "miDebuggerPath": "C:\\Program Files\\mingw-w64\\x86_64-8.1.0-win32-seh-rt_v6-rev0\\mingw64\\bin\\gdb.exe", // 这里需要填写你自己的gdb.exe的路径
            "setupCommands": [
                {
                    "description": "为 gdb 启用整齐打印",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

　　

测试代码如下（以矩阵运算库eigen为例）：main.cpp

#include <iostream>
#include "Eigen/Dense"

using namespace std;
using namespace Eigen;

typedef Matrix<float,1,Dynamic> MatrixType;

typedef Map<MatrixType> MapType;
typedef Map<const MatrixType> MapTypeConst;   // a read-only map


typedef Matrix<int, Dynamic, Dynamic,RowMajor> MatrixTypeInt;

typedef Map<MatrixTypeInt> MapTypeInt;
typedef Map<const MatrixTypeInt> MapTypeConstInt;   // a read-only map

int main()
{
    MatrixXf m(4,4);
    m<< 1,2,3,4,
        5,6,7,8,
        9,10,11,12,
        13,14,15,16;
    cout<<"Block in the middle"<<endl;
    cout<<m.block<2,2>(1,1)<<endl<<endl;
    for(int i = 1;i <= 3;++i)
    {
        cout<<"Block of size "<<i<<"x"<<i<<endl;
        cout<<m.block(0,0,i,i)<<endl<<endl;
    }

	int pp = 2, qq = 2;
	cout<<m.block(1,1,pp,qq)<<endl<<endl;

	int array[8];

	for(int i = 0; i < 8; ++i) array[i] = i;

	cout << "Column-major:\n" << Map<Matrix<int,2,4> >(array) << endl;

	cout << "Row-major:\n" << Map<Matrix<int,2,4,RowMajor> >(array) << endl;

	cout << "Row-major using stride:\n" <<

		Map<Matrix<int,2,4>, Unaligned, Stride<1,4> >(array) << endl;


	int data[] = {1,2,3,4,5,6,7,8,9};

	Map<RowVectorXi> v(data,4);

	cout << "The mapped vector v is: " << v << "\n";

	new (&v) Map<RowVectorXi>(data+4,5);

	cout << "Now v is: " << v << "\n";

	int tmpN1 = 2;
	int tmpN2 = 4;
	MatrixTypeInt tmp1(tmpN1, tmpN2);
	tmp1.setIdentity();
	MapTypeInt tmpMapInt(data, tmpN1, tmpN2);   // m2map shares data with m2
	cout<< tmp1<<endl;
	cout<< tmpMapInt<<endl;
	cout<< "11 qfr " << MapTypeInt(data, tmpN1, tmpN2)<<endl;

	int n_dims = 5;


	MatrixType m1(n_dims), m2(n_dims);

	m1.setRandom();

	m2.setRandom();

	float *p = &m2(0);  // get the address storing the data for m2

	MapType m2map(p,m2.size());   // m2map shares data with m2

	MapTypeConst m2mapconst(p,m2.size());  // a read-only accessor for m2

	cout << "m1: " << m1 << endl;

	cout << "m2: " << m2 << endl;

	cout << "Squared euclidean distance: " << (m1-m2).squaredNorm() << endl;

	cout << "Squared euclidean distance, using map: " <<

	(m1-m2map).squaredNorm() << endl;

	m2map(3) = 7;   // this will change m2, since they share the same array

	cout << "Updated m2: " << m2 << endl;

	cout << "m2 coefficient 2, constant accessor: " << m2mapconst << endl;

	/* m2mapconst(2) = 5; */   // this yields a compile-time error
}

　　

CMakeLists.txt 如下：

cmake_minimum_required(VERSION 3.0)
project(cmake_test_project)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -g")

include_directories( "E:\\code\\eigen-3.3.8" )

############### source ######################
set(
    rtk_tc_src_list
    ${CMAKE_CURRENT_SOURCE_DIR}/main.cpp
)

add_executable(${PROJECT_NAME} ${rtk_tc_src_list})
