解決DMA-210L開發平台在Ubuntu 12.04 LTS下編譯Android 2.3.4出現的問題

近日因緣際會測試到長高科技的 ARM Cortex A8 DMA-210L開發平台，由於該平台目前使用的是Android 2.3.4(Gingerbread)作業系統，加上Gingerbread在Ubuntu 12.04編譯上有些許地方需要修改，在這裡整理出來順便做個紀錄。

安裝環境:
請參考 "在 Ubuntu 12.04 LTS 安裝 Android SDK&NDK 開發環境"
http://www.cheng-min-i-taiwan.blogspot.tw/2012/05/ubuntu-1204-lts-android-sdk.html

以下是幾項錯誤訊息出現時所需要修改的地方:

....(略)....
frameworks/base/libs/utils/RefBase.cpp: In member function ‘void android::RefBase::weakref_type::trackMe(bool, bool)’:
frameworks/base/libs/utils/RefBase.cpp:483:67: error: passing ‘const android::RefBase::weakref_impl’ as ‘this’ argument of ‘void android::RefBase::weakref_impl::trackMe(bool, bool)’ discards qualifiers [-fpermissive]

frameworks/base/libs/utils/ResourceTypes.cpp:4375:43: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
解決方法是修改
frameworks/base/libs/utils/Android.mk line 60 :
在:
LOCAL_CFLAGS += -DLIBUTILS_NATIVE=1 $(TOOL_CFLAGS)
後面加 -fpermissive :
LOCAL_CFLAGS += -DLIBUTILS_NATIVE=1 $(TOOL_CFLAGS) -fpermissive

make: *** [out/host/linux-x86/obj/EXECUTABLES/obbtool_intermediates/Main.o] Error 1

解決方法是修改:
build/core/combo/HOST_linux-x86.mk line 61：

把：
HOST_GLOBAL_CFLAGS += -D_FORTIFY_SOURCE=0
改為：
HOST_GLOBAL_CFLAGS += -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0
