發現 , TI release 的 Android JB for AM335x 的 BSP 了 .
一樣 在 FC16 上 build 看看吧 !! 我的 PC 還是 FC16 , 所以應該缺少的 東西不多 !
想說可以順利build 完畢 , 沒想到 .... 第一步就有問題 !!
Cross Compile 給我用 64 bit 的 ..... 我的 FC16 是 32bit 啦 !!!!
不想使用 VM machine (build 太慢) , 並且有舊的 project toolchain (32Bit ) .
好吧 , 試試看是否能 在 32 bit build .
PS. 這篇文章會陸續增加 修正的項目 .
A.先改 ./prebuilts/tools/gcc-sdk/gcc 吧.
原始檔案使用 file -L "$SHELL" 的方式再次檢查是否 64 bit. 感
每次都用同樣方式檢查不就可以了 ?? 修改後的 diff 如下:

這一版本沒有 32bit 的 target toolchain , 所以由 ICS 的 版本內將的 toolchain
arm-linux-androideabi-4.4.x 複製到
./prebuild/linux-x86/toolchain/ 目錄下!!
原本應該在 ./prebuilds 下 , 不過擔心 ICS 的 toolchain 會有內部指定位置 , 所以放在和
ICS 一樣的 ./prebuild/ 目錄下.
本篇最後會有一個 env.sh 的 file , 內容會說明如何將 toolchain 指定到這邊 !!
B.Java VM 沒有辦法開啟 .
只細看一下 error message , 好像 jave 的 heap memory 太大 , 修正 下面這個檔案
./build/core/definitions.mk , diff 內容如下:
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

D.build 到 qemu 的時候會出錯
主要是 非 standalone 的時候會去 build 64bit 的 library , 這時候就出錯 !!
參考一下 Makefile.common 發現設定BUILD_STANDALONE_EMULATOR 會排除
64 bit 的 library 部份 , 先設定吧 , 到時候 qemu 要用的時候再來修正.
diff 後的 內容如下:

E.編譯到一半 會發現沒有 LIBBFD
LIBBFD 我不知道是啥東西 , 不過確定32bit 的 toolchain 沒有 , 所以修改./external/oprofile/common.mk , 這個 mk file中有指定toolchain 目錄 , 所以順便一起更改 . 只要 uname -m 是i686 就關閉 LIBBFD 和設定 32 bit 的 toolchain 位置 , diff 內容如下:
---------------------------------- common.mk ----------------------------------

F. 編譯到 frameworks/native/libs/utils 目錄的時後會出錯
原因是會去編譯 64 bit 的 static library.
檢查一下 Android.mk file 發現 , default 會編譯 64 bit static library ,
修改成不要編譯 (使用 uname -m 區別).

H.增加環境參數設定
為了容易設定環境參數 ,增加了一個 ./env.sh file 來協助整個環境的設定.
內容如下:
#!/bin/sh
# vi: set ts=4 :

目前已經可以build 完畢 , 接著要試試看有沒有問題.......
沒有想像的那樣容易 , 不能 working .
後來發現 64 bit 的系統可以跑32bit 的程式,只要安裝 所需要的 32bit library即可 ！！
舊的 Project 因為 code 的關係(int 大小不, 整個 struct 也會不對 ) 不能編譯成為 64 bit !!
不過可以在 CFLAGS & LDFLAGS 額外加上 -m32 就可以編譯成為
32 bit 的程式 , 當然對應的 32bit library 也要安裝 (ex zlib-devel.i686.....等)
乖乖的轉換 64 bit system , 並且不需要修改很多東西就可以了!!
