mac os 编译android源码坑点

mac os 编译android源码坑点

1）Case-insensitive filesystems not supported

mac os 当前的文件系统不区分大小导致的

解决

在我的1000元移动硬盘上

创建一个区分大小写的dmg
hdiutil create -type SPARSE -fs 'Case-sensitive Journaled HFS+' -size 200g android.dmg
直接将它挂在上
hdiutil attach android.dmg -mountpoint /Volumes/android 
不用了卸载
hdiutil detach /Volumes/android

2）internal error: Could not find a supported mac sdk: ["10.10" "10.11" "10.12" "10.13" "10.14"]

按照网上的方法去弄没几把吊用自己看源码，发现

执行的是xcrun 去查，网上现学现卖查了个go的打印，添加一行打印 如下，直接放到shell也找不到，应该还是找不到

解决：

 xcrun  --show-sdk-version 去对版本，目录那傻逼不知道为啥是错的

11.1 不行，最后改成10.15的版本弄好了

不清楚啥原因，重新拔了下我的移动硬盘，重新挂载就好了

 添加得到的版本就好了

3）too many open files

执行ulimit -S -n 1024

4)

external/iptables/include/linux/netfilter_ipv4/ipt_ECN.h:13:10: fatal error: 'linux/netfilter/xt_DSCP.h' file not found
#include 
         ^~~~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.

修改这个文件

//#include 
#include 
改成小写的
