开始折腾编译.LOS15.1(android8.1)，在此记录遇到的问题

1.大天朝下载源码是个问题，换个hosts即可，这里我用的是

https://github.com/googlehosts/hosts

手动黏贴hosts中的内容到/etc/hosts 拔掉网线重新插入即可

sudo gedit /etc/hosts

2.安装需要的依赖

sudo apt-get update && sudo apt-get install git-core gnupg flex bison gperf libsdl1.2-dev libesd0-dev libwxgtk3.0-dev squashfs-tools build-essential zip curl libncurses5-dev zlib1g-dev openjdk-8-jre openjdk-8-jdk pngcrush schedtool libxml2 libxml2-utils xsltproc lzop libc6-dev schedtool g++-multilib lib32z1-dev lib32ncurses5-dev gcc-multilib maven tmux screen w3m ncftp liblz4-tool pngquant rsync

不出意外这里安装lib32ncurses5-dev 会报如下错误

下列软件包有未满足的依赖关系：
lib32ncurses5-dev : 依赖: libncurses5-dev (= 6.0+20170715-2)
E: 无法修正错误，因为您要求某些软件包保持现状，就是它们破坏了软件包间的依赖关系。

解决方法替换软件源

sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
sudo gedit /etc/apt/sources.list

我这里用的阿里的文件如下

更新下

sudo apt-get update

错误:3 http://mirrors.aliyun.com/ubuntu trusty-security InRelease
由于没有公钥，无法验证下列签名： NO_PUBKEY 40976EAF437D05B5 NO_PUBKEY 3B4FE6ACC0B21F32

添加签名即可

sudo apt-key adv –keyserver keyserver.ubuntu.com –recv-keys 40976EAF437D05B5

完成

来，再执行更新

sudo apt-get update

然后安装刚才失败的lib32ncurses5-dev

sudo aptitude install lib32ncurses5-dev

这里进行的是降级安装 输入y y y…即可

下列“新”软件包将被安装。
lib32ncurses5-dev{b} lib32tinfo-dev{ab}
0 个软件包被升级，新安装 2 个，0 个将被删除， 同时 19 个将不升级。
