android 2.3.4 移植 到tiny6410

在Fedora 14（32位）上編譯android2.3.4 源碼，定製廠商 編譯記錄。

準備 ： 下載android 2.3.4的源碼，友善t提供的2.3.4 的源碼。

工具：友善交叉編譯工具

首先看編譯源碼

#source build/envsetup.sh 
#make

出錯
Checking build tools versions...
build/core/main.mk:76: ************************************************************
build/core/main.mk:77: You are attempting to build on a 32-bit system.
build/core/main.mk:78: Only 64-bit build environments are supported beyond froyo/2.2.
build/core/main.mk:79: ************************************************************
build/core/main.mk:80: *** stop.  Stop.

修改build/core/main.mk檔案將
#ifneq (64,$(findstring 64,$(build_arch)))
改為
ifneq (i686,$(findstring i686,$(build_arch)))
修改external/clearsilver/cs
external/clearsilver/cgi
external/clearsilver/java-jni
external/clearsilver/util
中的
#LOCAL_CFLAGS += -m64
#LOCAL_LDFLAGS += -m64
改為
LOCAL_CFLAGS += -m32
LOCAL_LDFLAGS += -m32

再編譯
#make
幾小時後，出錯：
sh: gperf: command not found
calling gperf failed: 32512 at ./makeprop.pl line 96.
make: *** [out/target/product/generic/obj/STATIC_LIBRARIES/libwebcore_intermediates/WebCore/css/CSSPropertyNames.h] Error 25
make: *** Deleting file `out/target/product/generic/obj/STATIC_LIBRARIES/libwebcore_intermediates/WebCore/css/CSSPropertyNames.h'

安裝gperf
#yum install gperf
再次編譯
#make

成功產生
Generated: (out/target/product/generic/android-info.txt)

二 定製

建立vendor檔案夾及相關子目錄檔案。參考友善vendor/friendly-arm/mini6410

改成自己想要的名稱

/home/android-20120519/Android-2.3.4 友善源碼檔案路徑 //用armv6-vfp，從友善的源碼中拷貝。
cp /home/android-20120519/Android-2.3.4/build/core/combo/arch/arm/armv6-vfp.mk build/core/combo/arch/arm/
cp /home/android-20120519/Android-2.3.4/build/core/vm build/core/

拷貝友善的編譯指令碼和JDK

拷貝 /home/android-20120519/Android-2.3.4/jdk1.6.0_23.tar.gz 

 /home/android-20120519/Android-2.3.4/setenv

 /home/android-20120519/Android-2.3.4/ genimages.sh

 /home/android-20120519/Android-2.3.4/ build-android

到自己編譯源碼目錄

進入自己源碼根目錄

#build-android

出錯
make: *** No rule to make target `out/target/product/DXQ6410/obj/lib/libaudio.so', needed by `out/target/product/DXQ6410/obj/SHARED_LIBRARIES/libaudioflinger_intermediates/LINKED/libaudioflinger.so'.  Stop.

cp /home/android-20120519/Android-2.3.4/external/android-vnc-server/ ./ -rf
cp /home/android-20120519/Android-2.3.4/external/alsa-* ./ -rf
#make clean
#build-android

出錯
system/core/debuggerd/vfp.S:21: Error: selected processor does not support `fconstd d15,#15'
make: *** [out/target/product/DXQ6410/obj/EXECUTABLES/vfp-crasher_intermediates/vfp.o] Error 1
make: *** Waiting for unfinished jobs....
修改system/core/debuggerd/vfp.S，加上 #ifdef __ARM_ARCH_7__ endif

#build-android 成功

燒錄，啟動失敗
在system/core/init/init.c 中508行增加：
if (!cur_command->func)
return;

在system/core/rootdir/Android.mk 中修改
file := $(TARGET_ROOT_OUT)/ueventd.rc
$(file) : $(LOCAL_PATH)/ueventd.rc | $(ACP)
$(transform-prebuilt-to-target)
ALL_PREBUILT += $(file)
$(INSTALLED_RAMDISK_TARGET): $(file)
改為：
ifneq ($(TARGET_PROVIDES_UEVENTD_RC),true)
file := $(TARGET_ROOT_OUT)/ueventd.rc
$(file) : $(LOCAL_PATH)/ueventd.rc | $(ACP)
$(transform-prebuilt-to-target)
ALL_PREBUILT += $(file)
$(INSTALLED_RAMDISK_TARGET): $(file)
endif
#make 成功
燒錄，啟動失敗

修改build/core/combo/select.mk 58行
$(combo_target)PRELINKER_MAP := $(BUILD_SYSTEM)/prelink-$(combo_os_arch).map
改為
ifeq ($($(combo_target)PRELINKER_MAP),)
$(combo_target)PRELINKER_MAP := $(BUILD_SYSTEM)/prelink-$(combo_os_arch).map
endif

將友善的build/core/prelink-linux-arm.map 拷貝覆蓋到源碼相應目錄
將友善的external/libusb 複製到源碼的external 目錄
#make
燒錄，啟動到android_ 畫面，迴圈列印init: untracked pid 1815 exited
通過logcat 
發現出錯在：

由於在 BoardConfig.mk 中我將# Bluetooth 設定為false，導致編譯沒有產生liba2dp.so 

更改後

BOARD_HAVE_BLUETOOTH := true
重新編譯，系統可以啟動。
但啟動中列印出一些錯誤：
binder: release 1576:1576 transaction 830 out, still active
binder: 1487:1493 transaction failed 29189, size 4-0
binder: send failed reply for transaction 830, target dead
binder: release 1636:1636 transaction 1109 out, still active
binder: 1487:1493 transaction failed 29189, size 14600-0

binder: send failed reply for transaction 1109, target dead

後續再研究。
