build whole android (AOSP) in Mac OS X Yosemite + Xcode 7.0.1(v10.5 SDK)

##My environment: Mac OX X 10.10.5(14F27) Xcode 7.0.1(7A1001) jdk1.7.0_80 jdk1.8.0_51 (Default)

First of course, download AOSP by official instructions except that i use android-5.1.1_r14 branch instead of android-4.0.1_r1.

Then what i did especically are:

##1. To avoid check error of OS X SDK version, run following command first: export build_mac_version=sw_vers -productVersion #for me, result is 10.10.5 export mac_sdk_version=10.9 #this is the biggest version AOSP build system support export mac_sdk_root=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk export gcc_darwin_version=11

##2. To skip disk case sensitive check and java version check, create a file TOP_AOSP_DIR/out/versions_checked.mk with contents: VERSIONS_CHECKED := 5 BUILD_EMULATOR ?= false

##3. To avoid error of some header files not found, create a symbol link MacOSX10.11.sdk/...c++/v1 => xctoolchain/...c++/v1:

sudo ln -s /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/include/c++/v1 /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/c++/v1

##4. AOSP's prebuild compiler for host side can not handle some latest header file of OS X SDK, i have no way, so modify following two files:

53c53,54
< static const CGFontIndex kCGGlyphMax = kCGFontIndexMax;
---
> //static const CGFontIndex kCGGlyphMax = kCGFontIndexMax;
> static const CGFontIndex kCGGlyphMax = ((1 << 16) - 2);

489a490
> #if MAC_OS_X_VERSION_MIN_REQUIRED > MAC_OS_X_VERSION_10_9
495a497
> #endif

OK, now you can make, as a tip, you can add "showcommands" option to make, and even combine more like following commands to save output with timestamp prefix to log file.

make -j4 -k showcommands 2>&1 | (while read line; do echo `date +"%Y-%m-%d %H:%M:%S"` $line; done) | tee out/make.log

Good luck
