VMware 安装 centOS 8

https://mirrors.aliyun.com/centos/8-stream/isos/x86_64/CentOS-Stream-8-x86_64-latest-dvd1.iso
https://blog.51cto.com/u_16596714/10118179
注意，swap分区不能像上述教程中设置2G，这样会出现后面build的时候的input/output错误，直接设置20G

添加ANDROID_NDK环境变量

vim ~/.bashrc添加环境变量，source ~/.bashrc使之生效

[root@localhost hgfs]# cat ~/.bashrc
# .bashrc

# User specific aliases and functions

alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'

# Source global definitions
if [ -f /etc/bashrc ]; then
    . /etc/bashrc
fi

export ANDROID_NDK=/mnt/hgfs/ndk/android-ndk-r21b

编译

说明
https://puerts.github.io/docs/puerts/unity/performance/il2cpp/

编译android+arm64

cd unity/native_src_il2cpp
node ../cli make --platform android --arch arm64

等待许久，报错了

百度了一下，是因为swap空间不足，故增加一个swap file
https://zhuanlan.zhihu.com/p/510257476
增加后：

[root@localhost ~]# swapon --show
NAME           TYPE      SIZE USED PRIO
/dev/nvme0n1p2 partition   2G   0B   -2
/swapfile      file       16G   0B   -3

再编译后成功生成：puerts/unity/Assets/core/upm/Plugins/Android/libs/arm64-v8a/libpuerts_il2cpp.a

编译android+armv7

root@localhost puerts]# ./build.sh
node --loader ts-node/esm /mnt/hgfs/puerts/unity/cli/cmd.mts make --platform android --arch armv7

又出现input/output的问题，这次应该和swap分区没关系了，看到下面这篇文章
http://t.csdnimg.cn/QArGJ
受其启发，我确实是把puerts工程通过共享文件夹并挂载到mnt后进行编译的，会不会与此有关？于是把工程copy到usr/works里再试试，果然编译成功：

[root@localhost armeabi-v7a]# ls -l /usr/works/unity/Assets/core/upm/Plugins/Android/libs/armeabi-v7a/libpuerts_il2cpp.a
