<title><![CDATA[Mac配置vscode进行C++开发]]></title>
<url>%2F2018%2F12%2F22%2FMac%E9%85%8D%E7%BD%AEvscode%E8%BF%9B%E8%A1%8CC-%E5%BC%80%E5%8F%91%2F</url>
<content type="text"><![CDATA[#前言 平时工作做C/C++方面的开发更多还是在Windows下使用Visual Studio，Qt，CodeBlock等。自己的电脑是macOS下使用过IDE性质的XCode,CLion,Qt Creator，也使用过轻量级的诸如TextMate, Sublime Text，vim。但始终没有宇宙最强IDE—MS家族的VS。那种操作体验爽。废话少说了，直接上教程 需求格式化自动补全Lint符号检索方便的跳转和查看可视化调试 步骤1.下载并安装Visual Studio Code2.检查自己的Mac是否安装了编译器，打开控制台。输入 g++ -v 和 clang++ -v如下图3.然后回到VSCode去安装如下图所示的两款插件，以获得C++语法高亮、错误检查和调试等功能。 那么，前期准备工作完成后进入具体的配置阶段。首先在目录下新建一个文件夹作为工程目录，然后在VSCode中打开该文件夹。在里面新建一个cpp文件命名为main.cpp。随意写点程序在里面。 12345678910#include<iostream>#include<stdlib.h>#include<stdio.h>using namespace std;int main(int argc, char const *argv[]){ cout<<"Hello~"<<endl; return 0;} 然后点击侧边栏的Debug按钮，点击设置图标，便会提示你选择环境，这里就选择C++那一项。 此时VSCode会在你的工程目录下自动新建一个.vscode的文件夹，并新建了一个launch.json的文件，这里需要对生成的文件进行一些小改动。本人配置如下： 1234567891011121314151617181920{ // 使用 IntelliSense 了解相关属性。 // 悬停以查看现有属性的描述。 // 欲了解更多信息，请访问: https://go.microsoft.com/fwlink/?linkid=830387 "version": "0.2.0", "configurations": [ { "name": "(lldb) Launch", "type": "cppdbg", "request": "launch", "program": "${workspaceFolder}/a.out", "args": [], "stopAtEntry": false, "cwd": "${workspaceFolder}", "environment": [], "externalConsole": true, "MIMode": "lldb" } ]} 保存后按快捷键⇧⌘B编译，此时会出现提示没有找到要运行的生成任务，所以接下来将进行生成任务的配置工作，VSCode提供了一些模版，有需要的可以自行选择，这里就选则Others。 此时.vscode目录下会出现一个task.json文件，对它进行改写。本人配置如下： 12345678910111213141516171819{ // See https://go.microsoft.com/fwlink/?LinkId=733558 // for the documentation about the tasks.json format "version": "2.0.0", "tasks": [ { "label": "hello world", "type": "shell", "command": "clang++", "args": [ "main.cpp" ], "group": { "kind": "build", "isDefault": true } } ]} 保存后再次按快捷键⇧⌘B就能够顺利编译了，编译完成后按F5执行，得到输出结果。 每次编译完成后，我们会发现目录下多了一个a.out文件，这个文件是Linux/Unix环境下编译器编译源代码并连接产生的可执行文件，在未指定的情况下其默认命名为a.out。那么如何通过修改配置文件来修改这个文件的命名呢？ 方法很简单，在task.json中的args属性下填入-o yourfilename.out，以本人的配置作为示例： 1234567891011121314151617181920{ // See https://go.microsoft.com/fwlink/?LinkId=733558 // for the documentation about the tasks.json format "version": "2.0.0", "tasks": [ { "label": "hello world", "type": "shell", "command": "clang++", "args": [ "-o app.out", "main.cpp" ], "group": { "kind": "build", "isDefault": true } } ]} 可以发现这里的command和args两个属性就相当于在命令行中执行了clang++ -o yourfilename.out main.cpp，所以如果还有其他的需求也可以对这里进行改写。最后不要忘记修改launch.json中的program属性，将.out的文件名修改为与task.json一致。便可以成功编译执行了。编译后结果如下图：]]></content>

<title><![CDATA[vsftpd服务器的移植]]></title>
<url>%2F2018%2F07%2F15%2Fvsftpd%2F</url>
<content type="text"><![CDATA[一、简介 vsftpd即very secure FTP daemon（非常安全的FTP进程），是一个基于GPL发布的类UNIX类操作系统上运行的服务器的名字（是一种守护进程），可以运行在诸如Linux、BSD、Solaris、HP-UX以及Irix等系统上面。vsftpd支持很多其他传统的FTP服务器不支持的良好特性。使用 vsftpd 可以在 Linux/Unix 系统上搭建一个安全、高性能、稳定性好的轻量级FTP服务器。 二、准备工作 vsftpd源码包 vsftpd-3.0.2.tar.gz 下载入口 arm-linux-gcc 交叉工具编译链 下载入口 linux平台（Ubuntu 12.04 32bit） 1PS:本人所使用的是arm-2009q1-203-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2 三、编译vsftpd源码1、解压 12# tar -xvf vsftpd-3.0.2.tar.gz -C /home/zhangxu/# cd /home/vsptfd-3.0.2 2、配置环境变量 1#export PATH = $PATH:/home/zhangxu/software/arm-2009q1/bin 3、修改Makefile和vsf_findlibs.sh 12345#vi Makefile CC = /home/myvpc/software/arm-2009q1/bin/arm-none-linux-gnueabi-gcc LIBS = './vsf_findlibs.sh' - lcrypt (参数- lcrypt ，否则编译提示找不到crypt) #vi vsf_findlibs.sh 注释掉49-59行 4、编译 1# make #编译，如果电脑是多核CPU，如四核，使用make -j4可提高编译速度 编译完成后，当前目录下会生成两个文件：vsftpd 和 vsftpd.conf，这两个文件是我们要用的。 四、复制vsftpd 和vsftpd.conf文件到目标板将生成的 vsftpd 复制到目标板 /usr/sbin 目录，vsftpd.conf 复制到目标板 /etc 目录，并修改vsftpd 为可执行，从PC上传到目标板方式任选，可以用tftp或者挂载的方式均可 1#chmod +x vsftpd 五、目标板FTP服务 配置使用 vi 打开 vsftpd.conf 文件，并进行配置，如下配置可实现正常上传下载功能： 12345678anonymous_enable=NO # 默认的 YES 改为 NOlocal_enable=YES # 删除前面的#号注释符号write_enable=YES # 删除前面的#号注释符号anon_upload_enable=NO # 删除前面的#号注释符号，并将 YES 改为 NOanon_mkdir_write_enable=NO # 删除前面的#号注释符号，并将 YES 改为 NOanon_other_write_enable=NO # 删除前面的#号注释符号，并将 YES 改为 NO（这一项新版本中可能没有） chroot_local_user=YES # 删除前面的#号注释符号，改行表示把FTP用户都限制在根目录中allow_writeable_chroot=YES # 添加本行到文件最后 再在目标版上使用命令行配置： 12# adduser nobody # vsftpd默认配置需要# mkdir /usr/share/empty # vsftpd默认配置需要 创建一个本地用户，并设置密码： 12345# adduser ftpadminChanging password for ftpadminNew password: Retype password: Password for ftpadmin changed by root 六、开启vsftpd服务配置完之后，在目标板上打开vsftpd，命令： 1# vsftpd & #注意，后面还有一个& 如果要让 vsftpd 开机启动，可以将该命令添加到 /etc/profile 或者 rc.local 文件最后。 七、 客户端测试]]></content>
