環境:Mac10.13.4

問題一:
system/core/base/logging.cpp:81:10: 'syscall' is deprecated: first deprecated in OS X 10.12 - syscall(2) is unsupported; 
please switch to a supported interface. For SYS_kdebug_trace use kdebug_signpost(). [-Werror,-Wdeprecated-declarations]


system/core/base/logging.cpp:81:10: error: 
'syscall' is deprecated: first deprecated in OS X 10.12 - syscall(2) is unsupported; 
please switch to a supported interface. 
For SYS_kdebug_trace use kdebug_signpost(). 
[-Werror,-Wdeprecated-declarations]
  return syscall(SYS_thread_selfid);
  
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk/usr/include/unistd.h:733:6: note: 'syscall' has been explicitly marked deprecated here

[  0% 142/32130] host C++: libbacktrac...tem/core/libbacktrace/BacktraceMap.cpp
ninja: build stopped: subcommand failed.
make: *** [ninja_wrapper] Error 1


解決方式:
去到/Applications/XCode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs，
發現MacOSX10.11.sdk已經被刪除，只剩下MacOSX10.12.sdk，
所以首先要去下載10.11的SDK。可以去MacOSX-SDKs下載MacOSX10.11.sdk，
解壓拷貝到/Applications/XCode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs。
為了避免下次升級的時候再被刪除，可以放到~/Document/MacOSX10.11.sdk，再給它建立一個軟連結：




問題二:
ninja: build stopped: subcommand failed.  
make: *** [ninja_wrapper] Error 1 

解決方式:
export JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx4096m"




問題三:
none of the installed SDKs (ac_sdk_versions_installed) match supported versions (10.8 10.9 10.10 10.11), trying 10.8  
直接找到這個檔案build/core/combo/mac_version.mk修改其中的 mac_sdk_versions_installed
加上我mac的版本10.13，解決了這個錯誤。




問題四:
build/core/config.mk:600: *** Error: could not find jdk tools.jar at /System/Library/Frameworks/JavaVM.
framework/Versions/Current/Commands/../lib/tools.jar, please check if your JDK was installed correctly.  Stop.  

解決方式:
找到:build/core/config.mk:600
找到:sh檔案:
讓ANDROID_JAVA_HOME = JAVA_HOME

問題五:
fatal error: too many errors emitted, stopping now [-ferror-limit=]  

解決方式:
將xcode切換為老版本

問題六:
FAILED: setup-jack-server
Jack server installation not found
到prebuilts/sdk/tools 目錄下執行一下這個命令：
./jack-admin install-server jack-launcher.jar jack-server-4.11.ALPHA.jar

問題七:
模擬器黑屏問題
emulator -kernel /Volumes/android/android-source/prebuilts/qemu-kernel/arm/kernel-qemu-armv7 -system system.img -data userdata.img -ramdisk ramdisk.img
又會提示:
New emulator backend requires minimum kernel version 3.10+ (currently got lower)
Please make sure you've got updated system images and do not force the specific kernel 
image together with the engine version
(新的模擬器後端需要最小核心版本3.10 +（當前更低）請確保您已經獲得了更新的系統映像，並且不要將特定核心映像與引擎版本一起強制。)

emulator -partition-size 1024 -skin WVGA854
編譯完成後啟動虛擬機器時,卡在黑屏,嘗試編譯aosp_arm64-eng解決.因此,這裡我使用了aosp_arm64-eng

問題八:
error: ro.build.fingerprint cannot exceed 91 bytes: Android/mini_emulator_x86/mini-emulator-x86:8.0.0/OPR6.170623.013/jkerte05091121:userdebug/test-keys (100)
1:編輯build/tools/post_process_props.py。換行如下：
PROP_NAME_MAX = 31
# PROP_VALUE_MAX = 91
PROP_VALUE_MAX = 128

2:編輯bionic/libc/include/sys/system_properties.h。換行如下：
#define PROP_NAME_MAX   32
// #define PROP_VALUE_MAX  92
#define PROP_VALUE_MAX  128

3:做
make clean
make
您也可以使用如下語法並行執行第二個make命令
make -j8

問題九:
frameworks/native/cmds/installd/installd.cpp:43:1: error: static_assert failed "Size mismatch."

frameworks/native/cmds/installd/installd_deps.h


// LY mod
// constexpr size_t kPropertyValueMax = 92u;

   constexpr size_t kPropertyValueMax = 128u;
