MacOSX 编译Android 4.0的各种问题

之前编译过Android 4.2的源码，当时按照Android官方文档来的，并且系统环境与官方

要求基本相同，所以编译起来比较容易，可以参阅我之前的博客。

最近比较悲催的事情接二连三，有天晚上无意间删除了之前编译的4.0的源码，在MacOSX10.0.2上编译各种错误，发现应该和系统环境有关系，Xcode编译器和Android 4.0不匹配，然后切换不同的Xcode，更悲催的事情发生了，在更新比较旧的Xcode的时候，系统没有响应了，然后我硬关机了，结果系统挂掉了，无奈之下，卸掉磁盘，备份磁盘的内容，然后通过网络重新更新回10.10.2。联网更新不会抹掉系统的内容，一切都和之前的一样，好来想到之前编译4.0的时候用的是10.9.2系统，所以就利用U盘做了个10.9.2的Maverick，在格式化磁盘之前，用时间机器备份了10.10.2的系统。

开始10.9.2的编译之旅，发现10.9.2利用高版本的Xcode的时候，编译出错和10.10.2是一样的

以上错误主要是因为Xcode和Android 4.0不匹配导致的，5.0.2以上版本都会出现这个问题，当前最新的版本是Xcode 6.2，利用Xcode 4.6.3就可以解决这个问题。

frameworks/compile/slang/slang_rs_context.h:69:28: error: private field 'mTarget' is not used [-Werror,-Wunused-private-field]
const clang::TargetInfo &mTarget;

这个问题主要是将warning当做error来处理了，需要修改frameworks/compile/slang目录下的Android.mk

将

local_cflags_for_slang := -Wno-sign-promo -Wall -Wno-unused-parameter -Werror

修改为，也就是却掉-Werror

local_cflags_for_slang := -Wno-sign-promo -Wall -Wno-unused-parameter

在编译iptables的时候会缺少一些文件

在external/iptables/include/linux目录下，添加缺少的文件，可以参阅http://git.oschina.net/androidsourcecode/external_iptables/tree/master/include/linux

这个问题和上面的Werror是一样的，修改frameworks/compile/libbcc目录下的libbcc-config.mk,

libbcc_CFLAGS := -Wall -Wno-unused-parameter -Werror

去掉上面的-Werror即可。

这个问题，不知道是什么原因导致的，代码编译到这里进行不下去了，因为我只是想利用源码来编译应用程序，至此，已经可以利用mmm来编译应用程序了，留作以后解决吧，有知情的恰巧路过的高人，指点一下，留下只言片语吧。

在编译qemu时候，出现如下错误

external/qemu/target-arm/exec.h:22:30: error: global register variables are not supported
register struct CPUARMState *env asm(AREG0);

没有搜索到相关信息，我注释掉register之后编译可以通过，但是会有类似上面的链接错误。

然后根据就注释掉和qemu相关的Android.mk内容，也就是没有编译相关代码，这个和emulator相关，我用不到，不过不编译确实说不过去。根据网上的一些信息，在这之前编译的sdk是4.6.3的10.9.sdk，然后安装10.5.sdk，但是还是出现这个链接错误，这个问题并没有解决。

修改./external/srec/srec/Recognizer/src/RecognizerImpl.c

replace all PINLINE with /*** PINLINE ***/ - actually remove all of them
