首先，本人以前没有使用过MacBook做过开发，对于MacBook不慎了解。
一、下载Android源码：
现在访问Android网站需要，因此建议使用清华大学的一个镜像来下载Android源码，具体可以百度一下。
二、编译Android源码：
2.1 创建一个镜像。
因为源码只能在大小写敏感的磁盘上编译（红色字体标示可以自行配置的参数，下同）
hdiutil create -type SPARSE -fs ‘Case-sensitive Journaled HFS+’ -size 100g~/android.dmg.sparsefile
这里分了100G硬盘
2.2 加载分区
hdiutil attach ~/android.dmg.sparsefile -mountpoint~/Android
2.3 下载相应的工具
java
下载jdk7: http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
jdk安装参考：http://docs.oracle.com/javase/7/docs/webnotes/install/mac/mac-jdk.html
make
2.4 修改文件描述符限制
在~/.bash_profile中添加以下内容：
# set the number of open files to be 1024
ulimit -S -n 1024
2.5 安装MacPort
If on the other hand you decide to install MacPorts from source, there are still a couple of things you will need to do after downloading the tarball before you can start installing ports, namely compiling and installing MacPorts itself:
1 “cd” into the directory where you downloaded the package and run “tar xjvf MacPorts-2.3.3.tar.bz2” or “tar xzvf MacPorts-2.3.3.tar.gz”, depending on whether you downloaded the bz2 tarball or the gz one, respectively.
2 Build and install the recently unpacked sources:
◦ cd MacPorts-2.3.3
◦ ./configure && make && sudo make install
3 Optionally:
◦ cd ../
◦ rm -rf MacPorts-2.3.3*
将/opt/local/bin和/opt/local/sbin添加到$PATH搜索路径中
编辑/etc/profile文件 $ sudo vim /etc/profile (特许编辑,强制保存退出 wq!)文件
export PATH=/opt/local/bin:$PATH
export PATH=/opt/local/sbin:$PATH
POSIXLY_CORRECT=1 sudo port install gmake libsdl git gnupg
如果出现Error: Port gmake not found，请用以下命令：
sudo port -d sync.
三、编译错误
3.1 xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance
解决办法：
1) Install Xcode (get it fromhttp://developer.apple.com) if you don’t have it yet,
2) Point xcode-select to the Xcode Developer directory using the following command:sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
Note: Make sure your Xcode app directory is the same as in the address above; most notably, it’ll be probably /Applications/Xcode-Beta.app/Contents/Developer if you installed beta XCode release instead.
3.2、Agreeing to the Xcode/iOS license requires admin privileges, please re-run as root via sudo.
解决办法：
根据提示 打开 Xcode 点击同意，就安装提示了，安装之后再看看 Ok。
3.3、build/core/combo/mac_version.mk:38: *****************************************************
build/core/combo/mac_version.mk:39: * Can not find SDK 10.6 at /Developer/SDKs/MacOSX10.6.sdk
build/core/combo/mac_version.mk:40: *****************************************************
build/core/combo/mac_version.mk:41: *** Stop.. Stop.
解决办法：
这是因为macos 10.10的Xcode已经更新到7.x了，同样sdk也更新到10.11。可以前往查看你得sdk版本，具体路径在：
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs
如果你跟我一样的系统版本，你会发现该目录下只有MacOSX10.11.sdk一个版本。没有10.6了，所以解决方案:
1) 装一个低版本的Xcode;
2) 改一下配置文件，修改方法为：
//前提是你在WORKING_DIRECTORY目录下
$ vi ./build//core/combo/mac_version.mk
//找到mac_sdk_versions_supported
mac_sdk_versions_supported := 10.6 10.7 10.8 10.9
//将上面这行换成
mac_sdk_versions_supported := 10.11 10.10 10.9
//就是换一下支持的sdk版本号。
3.4 system/core/include/log/log.h:35:20: error: stdarg.h: No such file or directory
解决办法：
这其实也是Xcode版本惹的祸！还是在build/core/combo/HOST_darwin-x86.mk里面
ifeq ($(mac_sdk_version),10.8 10.9)
# Mac SDK 10.8 no longer has stdarg.h, etc
host_toolchain_header := $(HOST_TOOLCHAIN_ROOT)/lib/gcc/i686-apple-darwin$(gcc_darwin_version)/4.2.1/include
HOST_GLOBAL_CFLAGS += -isystem $(host_toolchain_header)
endif
else
这里只判断了10.8 10.9。在10.8里面就已经没有stdarg.h了，那么在我们的10.9、10.10、10.11里面肯定也没有了。但是却没有走进这个判断。所以更改很简单，增加10.10 10.11的判断
3.5 host C++: validatekeymaps <= frameworks/base/tools/validatekeymaps/Main.cpp
解决办法：
需要下载老版本的Xcode来编译，下载地址：
