嵌入式开发 centos7 交叉编译环境准备

拼搏现实的明天。 2021-11-17 12:08 543阅读 0赞

1. 安装centos7,启动图像化界面。

参考:https://blog.csdn.net/qq\_23014435/article/details/74347925

\# systemctl get-default //获取当前系统启动模式

更改模式命令：systemctl set-default graphical.target由命令行模式更改为图形界面模式

systemctl set-default multi-user.target由图形界面模式更改为命令行模式

重启机器获得想要的启动界面。

2. centos7 安装samba

参考：https://www.cnblogs.com/hnxxcxg/p/6841778.html

关闭防火墙：systemctl disable firewalld.service

or  添加防火墙规则: firewall-cmd --permanent --zone=public --add-service=samba

firewall-cmd --reload

关闭selinux: vim /etc/selinux/config   设置：SELINUX=disabled

3.安装arm-linux-gcc

将 压缩包  tar zxvf xxx.tar  -C / 解压到根目录下

在  /root/.bashrc 下添加  export PATH=$PATH:/usr/local/arm/x.x.x/bin

source /root/.bashrc

4.安装arm  linux gdb server.

解压 tar zxvf  xxx.tar.gz

cd  arm-gdb-x.x

./buildall

第三步第四步，比较老的方式，新的方式参见：GNU  MCU Eclipse

3.介绍一下 xpm package manager

https://www.npmjs.com/package/xpm

`xpm` is a Node.js CLI application to manage xPacks.

xPacks are general purpose software C/C++ packages, intended to enhance code sharingand reusing during the development of C/C++ libraries and applications, much the same as npm modules do so nicely in the JavaScript ecosystem.

Xpacks类似于 javascript 生态圈的 npm ，旨在提高C/C++ 包管理，代码分享的效率和代码的重用性。

4.如何在linux 系统上安装xpm 包管理工具呢？

首先逃不开的还是要linux系统上安装npm 包管理工具，然后用npm 去安装xpm----OMG!!!。

https://www.digitalocean.com/community/tutorials/how-to-install-node-js-on-a-centos-7-server

(1) 安装 node.js

这里我们不用源码安装的方式，也不采用预编译的包的方式 而是采用最简单的

\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#坑\#\#\#\#\#\#\#\#\#\#\#  EPEL Repository 不是最新版本的 nodejs\#\#\#\#\#\#\#\#\#\#

Install a Package from the EPEL Repository

`sudo yum install epel-release`

`sudo yum install nodejs`

\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#坑\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#\#改用 预编译包的形式

下载 LTS 版本的  https://nodejs.org/download/release/latest-dubnium/

`sudo tar --strip-components 1 -xzvf node-v* -C /usr/local`

检查nodejs 版本

node --version

v10.14.2

（2）安装 xpm  参考: https://www.npmjs.com/package/xpm

$ mkdir -p "${HOME}"/Library/npm $ npm config set prefix "${HOME}"/Library/npm $ echo 'export PATH="${HOME}"/Library/npm/bin:${PATH}' >> "${HOME}"/.profile $ source "${HOME}"/.profile npm install --global xpm

检查 xpm 版本

xpm --version

0.4.5

(3) 利用xpm 安装交叉工具链

参考：https://gnu-mcu-eclipse.github.io/toolchain/arm/install/

`xpm install --global @gnu-mcu-eclipse/arm-none-eabi-gcc`

墙内速度比较慢: 参考github主页 https://github.com/gnu-mcu-eclipse/arm-none-eabi-gcc/releases

去github主页下载下来手动安装方法：

#### GNU/Linux ####

The GNU/Linux versions of **GNU MCU Eclipse ARM Embedded GCC** are packed as .tgz archives. Download the latest version named like:

*  `gnu-mcu-eclipse-arm-none-eabi-gcc-7.2.1-1.1-20180401-0515-centos64.tgz`
 *  `gnu-mcu-eclipse-arm-none-eabi-gcc-7.2.1-1.1-20180401-0515-centos32.tgz`

As the name implies, the binaries were created on CentOS, but can be executed on most recent GNU/Linux distributions (they were tested on Debian, Ubuntu, Manjaro, SuSE and Fedora). Select the `-centos64` file for 64-bit machines and the `-centos32` file for 32-bit machines.

To install the toolchain, unpack the archive and copy it to `/${HOME}/opt/gnu-mcu-eclipse/arm-none-eabi-gcc/`:

$ mkdir -p "${ HOME}"/opt $ cd "${ HOME}"/opt $ tar xf ~/Downloads/gnu-mcu-eclipse-arm-none-eabi-gcc-7.2.1-1.1-20180401-0515-debian64.tgz $ chmod -R -w "${ HOME}"/opt/gnu-mcu-eclipse/arm-none-eabi-gcc/7.2.1-1.1-20180401-0515 测试是否安装成功的方法：

$ "${ HOME}"/opt/gnu-mcu-eclipse/arm-none-eabi-gcc/7.2.1-1.1-20180401-0515/bin/arm-none-eabi-gcc --version arm-none-eabi-gcc (GNU MCU Eclipse ARM Embedded GCC, 64-bit)
