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)。

[ 編譯 libs 常見的錯誤 ]
- #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' eng_rsax.c:(.text+0x22a8): 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[2]: Leaving directory `/opt/openssl-1.0.1e/apps' 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。
