【RK3399】【Android7.1】Ubuntu16.04配置开发编译环境出现的问题

Platform: Firefly-RK3399
OS: Android 7.1
PC: Ubuntu 16.04

(1) ubuntu16.04 安装 lib32readline-gplv2-dev 出错，解决办法

直接用 lib32readline6-dev 替代：lib32readline-gplv2-dev

使用命令：

sudo apt-get install  lib32readline6-dev

(2) Android N 源码编译错误：Communication error with Jack

报错： Communication error with Jack server (58), try ‘jack-diagnose’ or see Jack server log

原因： Android7.0 JACK编译器不支持多用户同时编译，其他用户在编译，端口被占用

解决方法一： 重启一下jack服务
使用命令：

$ prebuilts/sdk/tools/jack-admin kill-server 
$ prebuilts/sdk/tools/jack-admin start-server 

解决方法二： 修改$HOME/.jack-settings和$HOME/.jack-server/config.properties中的端口号（比如都改为8058/8059），方可支持多用户同时编译。

修改文件$HOME/.jack-settings

# Server settings
SERVER_HOST=127.0.0.1
SERVER_PORT_SERVICE=8058
SERVER_PORT_ADMIN=8059
# Internal, do not touch
SETTING_VERSION=4            

修改文件$HOME/.jack-server/config.properties

#Thu Oct 17 06:33:14 PDT 2019
jack.server.max-jars-size=104857600
jack.server.max-service=4
jack.server.service.port=8058
jack.server.max-service.by-mem=1\=2147483648\:2\=3221225472\:3\=4294967296
jack.server.admin.port=8059
jack.server.config.version=2
jack.server.time-out=7200

注意：
两个文件中的端口号必须一致。
修改后的端口号必须是没有被使用的。
$HOME代表根目录

(3) Copying: out/target/common/obj/JAVA_LIBRARIES/core-all_intermediates/classes.dexninja: fatal: fork: Cannot allocate memory build/core/ninja.mk:148: recipe for target ‘ninja_wrapper’ failed

原因： 虚拟机分配内存不足，查看虚拟机内存分配只有4G左右

解决方法一： 关闭虚拟机，内存调整到6G，编译正常。

(4) 虚拟机内存分配不足导致的编译失败问题

解决方法： 修改prebuilts/sdk/tools目录下的jack-admin文件，添加 -Xmx4096m。
