關于OpenCV的安裝我這裡就不再贅述了 記得用brew并指定相關版本

在安裝成功後記得注意看它的提示文字

Warning: [email protected] dependency gcc was built with a different C++ standard
library (libstdc++ from clang). This may cause problems at runtime.
==> Caveats
[email protected] is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.
If you need to have [email protected] first in your PATH run:
  echo 'export PATH="/usr/local/opt/[email protected]/bin:$PATH"' >> ~/.zshrc
For compilers to find [email protected] you may need to set:
  export LDFLAGS="-L/usr/local/opt/[email protected]/lib"
  export CPPFLAGS="-I/usr/local/opt/[email protected]/include"
For pkg-config to find [email protected] you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/[email protected]/lib/pkgconfig”

在剛剛接觸這個IDE的時候,用到了code-runner這款插件,然而經過多次嘗試發現它隻能運作單個檔案,進入到設定(defaultSettings.json)當中不難發現:它的原理也就是幫我們在shell中輸入指令而達到編譯運作程式的目的。

...

	"code-runner.executorMap": {
		"javascript": "node",
		"java": "cd $dir && javac $fileName && java $fileNameWithoutExt",

但是和上篇文章MAC visual Studio Code 運作 調試c/c++ 配置(完美解決)

不同,我們的程式不光要能執行以及調試單純的算法程式,還要适用于需要引入頭檔案和連結庫的中型甚至大型項目,那麼這時候就該請出我們的神器

make

了,先不急 我們一點點看

項目目錄

下面是項目的簡單目錄

MAC下 VScode 運作 調試OpenCV 配置(完美解決)項目目錄c_cpp_properties.jsonlaunch.jsonsettings.jsontask.jsonMakefilemain.cpp運作調試參考文章

c_cpp_properties.json

在include的過程當中如果有問題,IDE會提示你并自動生成這個檔案,如果你是初學者沒關系,直接在’

.vscode

檔案夾中建立這個檔案就可以,如果是自動生成的稍作修改就可以,如果最後不行就按照我的改,我已經踩了無數的坑了,期間看過很多文章與教程,然而這是最終的版本。(當然了opencv的安裝位置和編譯器位置可能會不同,請各位看官自行調整,靈活一些)

小tips:

在vscode的json配置檔案中如果有不清楚的标簽一定要把滑鼠放在上面看一看說明,下同。

{
    "configurations": [
        {
            "name": "Mac",
            "includePath": [
                "${workspaceFolder}/**",
                "/usr/local/opt/[email protected]/include",
                "/usr/local/Cellar/[email protected]/3.4.5/include"
            ],
            "defines": [],
            "macFrameworkPath": [],
            "compilerPath": "/usr/bin/g++",
            "cStandard": "c11",
            "cppStandard": "c++11",
            "intelliSenseMode": "clang-x64",
            "browse": {
                "path": [
                    "/usr/local/Cellar/[email protected]/3.4.5/include"
                ],
                "limitSymbolsToIncludedHeaders": true,
                "databaseFilename": ""
            }
        }
    ],
    "version": 4
}
           

參數說明:

“includePath”

:後期需要添加的額外頭檔案路徑

“compilerPath”:

編譯器所在的檔案路徑

launch.json

這個檔案是在debug模式中需要用到并會自動生成的,稍作修改 ,注意:标簽

“program"

中檔案字尾和自身系統有關。

{
    // 使用 IntelliSense 了解相關屬性。 
    // 懸停以檢視現有屬性的描述。
    // 欲了解更多資訊,請通路: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(lldb) Launch",
            "type": "cppdbg",
            "request": "launch",
            "program": "${fileDirname}/${fileBasenameNoExtension}.out",

            "MIMode": "lldb",
            "preLaunchTask": "Build"
        }
    ]
}
           

"preLaunchTask"

:

"build hello world"

,是預設

launch.json

中沒有的,表示執行檔案前需要的編譯任務。具體的任務内容我們在

task.json

中定義。

settings.json

此settings是工作區設定, 另外還有一個使用者設定,它們之間的差別和聯系等相關知識請各位讀者自行了解。

//settings.json
{
    "python.pythonPath": "/Users/zjx/anaconda3/bin/python3",
    "code-runner.executorMap": {
        "c": "cd $dir && make  && ./$fileNameWithoutExt && make clean",
        "cpp": "cd $dir && make  && ./$fileNameWithoutExt && make clean"
    },
    "editor.renderWhitespace": "all",

        "/usr/local/Cellar/[email protected]/3.4.5/include"
    ]
}
           

task.json

首先快捷鍵

shift+command+p

打開Tasks: Configure Tasks,選擇 Create tasks.json file from templates,此時會蹦出一個下拉清單,在下拉清單中選擇Others,然後稍作修改如下

    // See https://go.microsoft.com/fwlink/?LinkId=733558

上面那一長串究竟是怎麼來的呢 在終端中輸入以下指令試試

pkg-config opencv --libs —cflags
MAC下 VScode 運作 調試OpenCV 配置(完美解決)項目目錄c_cpp_properties.jsonlaunch.jsonsettings.jsontask.jsonMakefilemain.cpp運作調試參考文章

按照json格式改好了就可以寫進去了,别問為啥,學。

Makefile

TARGET = ./main

SRCS := $(wildcard ./src/*.cpp ./*.cpp)

OBJS := $(patsubst %cpp,%o,$(SRCS))

CFLG = -g -Wall -I/usr/local/Cellar/[email protected]/3.4.5/include -Iinc -I./ -std=c++11

LDFG = -Wl, $(shell pkg-config opencv --cflags --libs)

CXX = g++

$(TARGET) : $(OBJS)
	$(CXX) -o $(TARGET) $(OBJS) $(LDFG)

%.o:%.cpp
	$(CXX) $(CFLG) -c $< -o [email protected] 

.PHONY : clean
clean:
	-rm ./*.o
           

main.cpp

// main.cpp
#include <opencv2/opencv.hpp>
#include <opencv2/highgui.hpp>
using namespace cv;
int main(int argc, char **argv)
{
	Mat img = cv::imread(argv[1], -1);
	if (img.empty())
		return -1;
	cv::namedWindow("Example1", cv::WINDOW_AUTOSIZE);
	cv::imshow("Example1", img);
	cv::waitKey(0);
	cv::destroyWindow("Example1");
	return 0;
	// Mat img = imread("/Users/zjx/Desktop/123.png");c
	// cv::imshow("image", img);
	// cv::waitKey();
	// return 0;
}

           

運作

control + option + N

利用code-runner插件進行快速運作:

Tips :對于本程式的話 ,記得傳參,可以修改makefile也可以修改settings也可以編譯後在終端中運作并傳參,看個人喜好

調試

shift + command + B

進行編譯 然後

F5

啟用調試 或者直接在左邊調試視窗按下綠色三角按鈕,相當于

編譯+啟動調試

,如下圖 完美解決。

最近這幾天真的在全身心解決這個問題(從這麼多的參考文章中能否看出來麼=。= ),因為網上大多數教程都是針對windows的 就算是mac環境下 xcode的教程也是更多一些,然後買了個相關課程,希望能從中找到關于環境搭建方面的技巧與經驗,結果!老師說:大家就用windows吧,用linux和MAC的都是高手,因為要掌握cmake神馬的balabala。。。當時很想放棄,結果還是熬過來了 現在回頭看看雖然這些東西不難,但是這期間确實學到了很多東西,也希望大家在今後的學習生活中不要被困難打倒。
