How to fix:
sudo apt-get install lib64z1-dev libc6-dev-amd64 g++-multilib lib64stdc++6

 

3.you need install flex,g++

 

4.

在Ubuntu 10.04编译Android froyo的时候一直出现一个错误。

Could not load 'clearsilver-jni'
java.library.path = out/host/linux-x86/lib
make: *** [out/target/common/docs/api-stubs-timestamp] 错误 45

 

我的JDK是1.6.0的，不知道是那里错了，查看/out/target/product/generic文件夹下生成了如下文件

ramdisk.img
Android-info.txt
clean_steps.mk
previous_build_config.mk
userdata.img

只有这五个文件，少了个system.img。

Android系统编译不能使用1.6，只能使用1.5。

clearsilver-jni 找不到的原因是jdk不匹配，我使用的是jdk1.6编译的，在eclair阶段使用1.6是正常的，froyo却出错了。改回jdk1.5，ok！正常编译。

 

更新jdk命令

https://help.ubuntu.com/community/Java

 

java虚拟机使用的是ubuntu默认的。需要现安装jdk1.5.0，然后在调用

• Open a Terminal window

• Run sudo update-java-alternatives -l to see the current configuration and possibilities.

• Run sudo update-java-alternatives -s XXXX to set the XXX java version as default. For Sun Java 6 this would be sudo update-java-alternatives -s java-6-sun

• Run java -version to ensure that the correct version is being called.

之后make即可
