OS X 10.10.5编译Android5.1.1源码

--------------------------------------------------写在前面--------------------------------------------------

由于在编译过程中遇到了很多奇奇怪怪的、难解的问题~~~

到后面，实际上还是在macmini中安装了Ubuntu系统，最后在Ubuntu系统下完成的Android源码编译。

以下就是在OS X系统中进行编译时遇到的一些问题和解决办法，聊作记录。

--------------------------------------------------写在前面--------------------------------------------------

参考：Build Android 5.1.1 on OSX 10.10 Yosemite With Xcode7

一、环境配置

电脑：Mac Mini (OS X 10.10.5)

内存：2 GB 1333 MHz DDR3

XCode:XCode 7.1 beta

二、错误

(1)

select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

解决办法：

sudo xcode-select --switch /Applications/Xcode-beta.app

(2)

build/core/combo/mac_version.mk:: *****************************************************
build/core/combo/mac_version.mk:: * Can not find SDK 10.10 at /Developer/SDKs/MacOSX10..sdk
build/core/combo/mac_version.mk:: *****************************************************

解决办法：在build/core/combo/mac_version.mk文件中将mac_supported_versions 增加10.11

mac_sdk_versions_supported :=  10.6 10.7 10.8 10.9 10.10 10.11

(3)

build/core/main.mk:: ************************************************************
build/core/main.mk:: You are building on a case-insensitive filesystem.
build/core/main.mk:: Please move your source tree to a case-sensitive filesystem.
build/core/main.mk:: ************************************************************
build/core/main.mk:: *** Case-insensitive filesystems not supported.  Stop.

Android源代码必须在大小写敏感的文件系统下编译，而Mac OS默认不是大小写敏感的，因此需要创建一个大小写敏感的磁盘分区。

解决办法：

使用磁盘工具分出一个格式为（MAC OS 日志式、区分大小写）的分区。

出现“分区无法验证”的错误提示“无法分区”时，重启电脑，在电脑一启动时按下COMMAND+S不动，进入单用户模式，输入fsck -f命令，修复磁盘后，输入reboot重启电脑，再次用磁盘工具进行分区即可。

host C++: validatekeymaps <= frameworks/base/tools/validatekeymaps/Main.cpp
<built-in>:: error: Unknown value ‘10.11’ of -mmacosx-version-min

make: *** [out/host/darwin-x86/obj32/EXECUTABLES/validatekeymaps_intermediates/Main.o] Error 

解决办法：

在build/core/combo/HOST_darwin-x86.mk里面，增加10.10 10.11的判断：

ifneq ($(filter 10.8 10.9 10.10 10.11, $(mac_sdk_version)),)
# Mac SDK 10.8+ no longer has stdarg.h, etc
host_toolchain_header := $($(combo_2nd_arch_prefix)HOST_TOOLCHAIN_ROOT)/lib/gcc/i686-apple-darwin$(gcc_darwin_version)/4.2./include
$(combo_2nd_arch_prefix)HOST_GLOBAL_CFLAGS += -isystem $(host_toolchain_header)
endif

(5)

<built-in>:: error: Unknown value ‘10.11’ of -mmacosx-version-min
make: *** [out/host/darwin-x86/obj32/EXECUTABLES/validatekeymaps_intermediates/Main.o] Error 

解决办法：

下载低版本的XCode（XCode 6.1.1），获取OS X 10.9的SDK.
