android 編譯過程及錯誤處理

1、下載核心安裝jdk後，make出現：/android/prebuilt/linux-x86/toolchain/arm-linux-androideabi-4.4.x/bin/arm-linux-androideabi-gcc: 許可權不夠，

可以看到是許可權不夠，因為在編譯完成arm-linux-androideabi-gcc檔案後，並沒有設定為可執行(具體看Linux許可權),樓主開啟命令列，切換到檔案所在目錄，chmod 777 file，就可以了。

/bin/bash: build/core/find-jdk-tools-jar.sh: Permission denied

同上，為了防止出現同樣錯誤，將android全部檔案加上執行權利。

2、ld/core/base_rules.mk:479: warning: ignoring old commands for target `out/target/product/msm7627a/system/etc/permissions/platform.xml'

解決辦法：

cd /usr/bin

必須先進入/usr/bin，下同

sudo ln -s -f /usr/lib/jvm/jdk1.6.0_30/bin/jar

我的jdk是安裝在/usr/lib/jvm/jdk1.6.0_30/目錄下的

如果提示javah：commond not found，於是照葫蘆畫瓢，輸入命令

cd /usr/bin
ln -s -f /usr/lib/jvm/jdk1.6.0_30/bin/javah

        && mkdir -p out/target/common/docs/doc-comment-check/assets-sdk \
        && cp -fr build/tools/droiddoc/templates/assets/* out/target/common/docs/doc-comment-check/assets/ \
        && cp -fr build/tools/droiddoc/templates-sdk/assets-sdk/* out/target/common/docs/doc-comment-check/assets-sdk/ \
        && touch -f out/target/common/docs/doc-comment-check-timestamp \
    ) || (rm -rf out/target/common/docs/doc-comment-check out/target/product/msm7627a/obj/JAVA_LIBRARIES/doc-comment-check_intermediates/droiddoc-src-list; exit 45)
/bin/bash: line 1: javadoc: command not found
make: *** [out/target/common/docs/doc-comment-check-timestamp] Error 45

 在編譯android環境時，java -version 命令明明能夠正確表示java已經安裝成功，環境設定正確。但是，在編譯android時，檢查java版本卻通不過去：提示/bin/bash: java: command not found  問題，

重裝jdk幾次仍是出現這種問題，沒辦法只好做個軟連結了。

 

   sudo ln -s /jdk1.6.0_21/bin/jar /bin/jar

   sudo ln -s /jdk1.6.0_21/bin/java /bin/java

   sudo ln -s /jdk1.6.0_21/bin/javac /bin/javac

   sudo ln -s /jdk1.6.0_21/bin/javah /bin/javah

   sudo ln -s /jdk1.6.0_21/bin/javadoc /bin/javadoc

終於：可以編譯通過了。。。

3、

編譯android時
lzop: error while loading shared libraries: liblzo2.so.2: cannot open shared object file: No such file or directory
    安裝：liblzo2-2-32bit-2.06-6.1.2.x86_64.rpm(apt-get install liblzo2-2)

sudo apt-get install liblzo2-dev
sudo apt-get install lzop
sudo apt-get install alien #alien預設沒有安裝，所以首先要安裝它
sudo alien liblzo2-2-32bit-2.06-6.1.2.x86_64.rpm
#將rpm轉換位deb，完成後會產生一個同名的xxxx.deb(http://rpmfind.net/linux/rpm2html/search.php?query=liblzo2.so.2)
sudo dpkg -i liblzo2-2-32bit-2.06-6.1.2.x86_64.deb #安裝
