隨著Android大軍的日益增多犬绒，從之前會(huì)敲HELLO WORLD就能找個(gè)不錯(cuò)的薪資驯妄，到現(xiàn)在不研究點(diǎn)源碼都不好意思說(shuō)你會(huì)Android诈胜，下面拋點(diǎn)Android源碼編譯的一些坑贼涩，os 10.12 ?Xcode 8.3 jdk 1.7/1.8
坑一：
Could not find a supported mac sdk: ["10.8" "10.9" "10.10" "10.11”]
解決方案：xcode版本不匹配引起的描睦。Xcode 8.3 sdk是10.12
1言缤，去https://github.com/phracker/MacOSX-SDKs下載對(duì)應(yīng)sdk版本嚼蚀，如10.11
2 將下載的sdk放在目錄/Applications/XCode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/中
坑二：
out/target/product/generic/obj/STATIC_LIBRARIES/libext4_intermediates/libipt_ECN.o
Infile included fromout/target/product/generic/obj/STATIC_LIBRARIES/libext4_intermediates/libipt_ECN.c:11:0:
external/iptables/extensions/../include/linux/netfilter_ipv4/ipt_ECN.h:13:37: fatal error: linux/netfilter/xt_DSCP.h: No such fileordirectory#include ^
compilation terminated.make:*** [out/target/product/generic/obj/STATIC_LIBRARIES/libext4_intermediates/libipt_ECN.o] Error1make:*** Waiting for unfinished jobs....
解決方案：在對(duì)應(yīng)目錄下新建xt_DSCP.h文件(/Volumes/Android/source/external/iptables/include/linux/netfilter/):
ps:你會(huì)發(fā)現(xiàn)有同名文件，個(gè)人懷疑區(qū)分大小寫(xiě)的問(wèn)題管挟，導(dǎo)致找不到轿曙。

坑三：
make: *** [out/host/common/obj/JAVA_LIBRARIES/doclava_intermediates/javalib.jar] Error 41
make: *** Waiting for unfinished jobs....
解決方案：jdk正常安裝的情況下，jdk環(huán)境變量配置有問(wèn)題
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home
