Cross compile libraries for Android

前置作業:產生 standalone toolchain

cross compile 需要用到的 libraries.

dependencies:mhash,bz2,zlib,libxml,and more.

下載點:提供修改過後的版本,官方下載點也可,不過有些地方需要自己自行修改,會寫在每個 libs 裡的 bash script file for auto conf. 做註解

bash script file 若是自己編輯的,需要把權限改為可執行檔。(executable) 即:chmod 700 /path/to/android-configure

也可以自行下載其他版本的 libraries 做編譯,如果有遇到錯誤,則可以去 MEGA 載點參考 libraries 中的檔案或是 android-toolchain 裡的檔標頭案。裡面的標頭檔都附已修正過的。

就試著 try and error 吧,改成正確的。

下載點記得把裡面的目錄:_install 刪除並做:make distclean (OpenSSL 是 make dist 與 make clean。 ) 才可以清掉之前編譯的內容與 Makefile。

(也有 Android toolchain 可以參考)

環境變數 TOOLCHAIN 需改成自己正確的路徑與安裝路徑 (–prefix)。

下面各個 source 的 MEGA 載點

souce 目錄裡面的 android-configure 檔案即為下面的各個 libs 的 bash script file

[ 編譯 libs 常見的錯誤 ]

  1. #include <xxxx.h> no such file or directory

解法找到哪個標頭檔案出問題,接著去尋找檔案,把有問題檔案裡的 #include 到正確的位置。(通常是用到產生的 standalone Android toolchain 裡的檔案)

可以使用下面指令找到相關位置的路徑檔。只截取有 android-toolchain 相關的 ouput strings .

 locate your-file.h | grep android-toolchain 

    2. undefined reference ‘XXX’ :有標頭檔沒有對應到相對應的參數,需要自行增加。(因為有些預設 Android toolchain 本身就沒有這個參數)

    3. ….parameter ‘xxxx’ no such parameters:沒有相對應的參數,這個錯誤目前出現較少。

4. 在 autoconf 時,出現 cannot recognize stsyem name “arm-linux-androideabi” source 裡附的 config.guess 和 config.sub 版本太舊,解決方式是從附的 MEGA 載點下載一個 libs 拿裡面這兩個檔案做覆蓋。

[ OpenSSL 錯誤 ]


../libcrypto.a(eng_rsax.o): In function `e_rsax_bn_mod_exp':
eng_rsax.c:(.text+0x132f): undefined reference to `mod_exp_512'
../libcrypto.a(eng_rsax.o): In function `e_rsax_rsa_mod_exp':
eng_rsax.c:(.text+0x1c08): undefined reference to `mod_exp_512'

../libcrypto.a(e_rc4_hmac_md5.o): In function `rc4_hmac_md5_cipher':
e_rc4_hmac_md5.c:(.text+0x44e): undefined reference to `rc4_md5_enc'
e_rc4_hmac_md5.c:(.text+0x4f1): undefined reference to `rc4_md5_enc'
collect2: error: ld returned 1 exit status
make[2]: *** [link_app.] Error 1

make[1]: *** [openssl] Error 2
make[1]: Leaving directory `/opt/openssl-1.0.1e/apps'
make: *** [build_apps] Error 1

原因是未設定 target 作業系統,設定成:linux-armv4 即可,可以參考前面的 bash script file for OpenSSL .

[ 參考資料 ]

DroidPHP (與PHP 和 lighttpd 相關 dependencies 內容不齊全,可能是作者還正在撰寫中吧,沒有提到相關編譯的錯誤,只有列出需要編譯的 libs)

build-libxm.sh (bash script file 可以做為 auto conf libxml 的參考)

 

[後記]

網路上很多文章就只有提到參數該怎麼設定,很少提到錯誤怎麼解決,這篇文章算是整個整理過後的心得。

萬一自己編譯有問題或是遇到非上述的 general errors 時,可以從提供的 MEGA 載點下載不同版本的 Android toolchain 參考檔案要如何加註與修改 header 檔中的 preprocessor code。
