因为工作需要，用了Linux来开发新产品，然后现在要学习搭建镜像。并且随手记录遇到的一些问题和如何解决。

开发板：NXP imx8mqevk

开发平台：VM

Ubuntu：18.04.3LST

工具：Yoctor

指导：i.MX Yocto Project User's Guide

以下安装环境默认Ubuntu18.03.4

安装完Ubuntu之后该有的操作我就不多说了

1.安装Host packages

对应的是文档里的3.1

命令：

sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \ build-essential chrpath socat cpio python python3 python3-pip python3-pexpect \ xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev \ pylint3 xterm

 一次性不行就分开来输入

sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib  
sudo apt-get install build-essential chrpath socat cpio python python3 python3-pip python3-pexpect  
sudo apt-get install xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev 
sudo apt-get install pylint3 xterm

2.安装repo

这里有两种方式：

2.1：在主目录中创建一个bin文件夹

命令：

mkdir ~/bin
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/bin/repo
chmod a+x ~/bin/repo

然后将以下一行添加到.bashrc文件中，以确保~/bin文件夹在PATH变量中

export PATH=~/bin:$PATH

2.2安装repo的另一个选项是使用Ubuntu软件包管理系统。

 sudo apt-get install repo

3.Yocto项目设置

首先，请确保使用下面的命令正确地设置了git

git config --global user.name "Your Name"
git config --global user.email "Your Email"
git config --list

然后开始下载

mkdir imx-yocto-bsp
cd imx-yocto-bsp
repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-zeus -m imx-5.4.3-1.0.0.xml
repo sync

3.1repo init错误解决

目录

以下安装环境默认Ubuntu18.03.4

1.安装Host packages

2.安装repo

2.1：在主目录中创建一个bin文件夹

2.2安装repo的另一个选项是使用Ubuntu软件包管理系统。

3.Yocto项目设置

4.构建配置

4.1DISTRO配置的列表

 4.2选择一个IMX Yocto 项目图像

目录

以下安装环境默认Ubuntu18.03.4

1.安装Host packages

2.安装repo

2.1：在主目录中创建一个bin文件夹

2.2安装repo的另一个选项是使用Ubuntu软件包管理系统。

3.Yocto项目设置

3.1repo init错误解决

4.构建配置

4.1DISTRO配置的列表

 4.2选择一个IMX Yocto 项目图像

4.3构建镜像

4.4如果编译安装过程中依赖包出错，解决方式

然而到了只一步之后大部分会卡在第三句的repo init这里，因为资源都在国外，当然了，如果你有代理的话应该就不会出现这个问题

请参考：Linux ubuntu repo安装方法

修改完成之后应该是这样的

 然后到了这里就说明链接到了，可以下载资源了

然后：repo sync 一下

4.构建配置

4.1DISTRO配置的列表

fsl-imx-wayland
fsl-imx-xwaylandsupported.
fsl-imx-fb

 DISTRO=fsl-imx-wayland MACHINE=imx8mqevk source imx-setup-release.sh -b IMX8mqevk

4.3构建镜像

我的选择是 imx-image-full   构建一个具有机器学习特性的开源Qt5图像。

bitbake imx-image-full

接下来就是漫长的等待了

4.4 CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none 解决

跑到了gstreamer1.0_1.16.imx.bb的时候出现了Error

提示gitlab服务器证书验证失败，没有CRLfile

解决方法1:参考链接 AUKO16的更换证书方法

解决方法2：在环境变量中加入

export GIT_SSL_NO_VERIFY=1

解决方法3：取消ssl证书 参考今夜睡火星大佬的方法

我是第三个方法最终解决了

又报错了：

ERROR: Logfile of failure stored in: /opt/imx8mq/OK8MQ-linux-sdk/imx-yoctor-bsp/IMX8mqevk/tmp/work/aarch64-poky-linux/qtdeclarative/5.13.2+gitAUTOINC+4080025fed-r0/temp/log.do_compile.2582
 

重新 repo sync了一下又继续编译，通过了又又报错了：

 ERROR: boost-1.71.0-r0 do_compile: Execution of '/opt/imx8mq/OK8MQ-linux-sdk/imx-yoctor-bsp/IMX8mqevk/tmp/work/aarch64-poky-linux/boost/1.71.0-r0/temp/run.do_compile.111645' failed with exit code 1:

然后去opt/imx8mq/OK8MQ-linux-sdk/imx-yoctor-bsp/IMX8mqevk/tmp/work/aarch64-poky-linux/boost/1.71.0-r0/temp/log.do_compile.111645看了日志后；

 百度了一下，说是虚拟机内存不够，后来想了想，我就把8个线程改成了4个，问题解决了

继续报错：

 把对应的 bb文件里面的git改成gitsm

成功了

新错误：

查看log.do_fetch.7566得知 

fatal: unable to access 'https://github.com/dmlc/dmlc-core/': gnutls_handshake() failed: The TLS connection was non-properly terminated.

还在编译中，未完待续。。。
