先放下我自己編譯成功本機的環境：
windows 10下的自帶的linux子系統
Distributor ID: Ubuntu
Description: Ubuntu 18.04.1 LTS
Release: 18.04
Codename: bionic
NDK= android-ndk-r10d
ANDROID_TOOLCHAIN = 'arm-linux-androideabi-4.9'
錯誤1：
Exception: ANDROID_NDK_ROOT environment variable not set：
詳情如圖：
scons: Reading SConscript files ...
********** Configuring Build Target = arm-android-linux / Release ********
Exception: ANDROID_NDK_ROOT environment variable not set:

這個錯誤比較簡單，直接從錯誤信息能夠判斷出是環境變量沒有設置，直接執行：
export ANDROID_NDK_ROOT=/mnt/f/android_ndk/android-ndk-r10d
地址是自己本機實際的ndk路徑
錯誤2：

什麼？編譯工具竟然找不到，找了一些參考資料發現是機器架構的指定問題，修改Build/Targets/arm-android-linux/Config.scons即可，‘-’號和‘+’號是我本地的git修改記錄
PLATFORM_TO_TARGET_MAP = {
- 'linux-i386' : 'linux-x86',
- 'linux2' : 'linux-x86',
+ 'linux-i386' : 'linux-x86_64',
+ 'linux2' : 'linux-x86_64',
'win32' : 'windows',
'cygwin' : 'windows',
'darwin' : 'darwin-x86'
問題3：
aarch64-linux-android-g++: error: unrecognized command line option '-msoft-float'
aarch64-linux-android-g++: error: unrecognized command line option '-mthumb-interwork'
不識別的命令
解決辦法：修改Build/Targets/arm-android-linux/Config.scons交叉編譯工具的版本即可
ANDROID_TOOLCHAIN = 'arm-linux-androideabi-4.9
問題4：
In file included from Source/Core/PltUPnP.h:45:0,
from Source/Tests/FileMediaServer/FileMediaServerTest.cpp:39:
Source/Core/PltTaskManager.h:45:21: fatal error: Neptune.h: No such file or directory
#include "Neptune.h"
直接cd進Neptune，發現竟然是空的（lll￢ω￢)，只能自己下載Neptune庫了，下載完畢，將Neptune的Source和ThirdParty拷貝至Neptune中即可
這時按照官網執行命令即可：
> scons target=arm-android-linux build_config=Release
> cd Source/Platform/Android/module/platinum
> ndk-build NDK_DEBUG=0
成功編譯：
