android 源码编译遇到得一些问题

转自http://blog.csdn.net/marlene0312/article/details/6165119

开发环境是fedora14 2.6.35.10-74.fc14.i686
android源码得获取和编译看官网链接
http://source.android.com/source/download.html

 

1.执行build/envsetup.sh脚本，配置环境变量

2.网上搜索到的
在使用：
$ repo init -u git://Android.git.kernel.org/platform/manifest.git
$ repo sync
下载完代码后，进行make，
$cd ~/mydroid
$make
却出现了如下错误：
build/core/main.mk:73: You are attempting to build on a 32-bit system.
build/core/main.mk:74: Only 64-bit build environments are supported beyond froyo/2.2.
这是因为froyo/2.2默认只支持64-bit，看到有些网友还要去下载64-比他的操作系统，很是麻烦，于是通过不断搜索资料终于解决，

解决办法：
需要进行如下修改即可，
将
./external/clearsilver/cgi/Android.mk 
./external/clearsilver/java-jni/Android.mk 
./external/clearsilver/util/Android.mk 
./external/clearsilver/cs/Android.mk
四个文件中的
LOCAL_CFLAGS += -m64 
LOCAL_LDFLAGS += -m64 
注释掉，或者将“64”换成“32”
LOCAL_CFLAGS += -m32 
LOCAL_LDFLAGS += -m32 

然后，将
./build/core/main.mk 中的
ifneq (64,$(findstring 64,$(build_arch))) 
改为：
ifneq (i686,$(findstring i686,$(build_arch))) 

 

3./bin/gperf库出错

解决：安装gperf库

 

4.make: *** [out/target/common/docs/api-stubs-timestamp] 错误 45

解决：

make clean
make update-api
make

 

5.安装jdk1.5.0.22的包，重新编译。

 

Which version of JDK should I use to build Android?

A: Only JDK 5.0.12 - 5.0.22 can be used to build Android. If you already installed JDK 6, you need download and install the JDK 5 from here and export the JDK 5 path to build Android.

 

 

6.make: *** [out/host/linux-x86/obj/EXECUTABLES/vm-tests_intermediates/tests] Error 1

解决： You can add the following lines to the end of the file /etc/security/limits.conf(before the line # End of file)

 

*       soft  nofile   8192                                                      *       hard  nofile   8192

 

and reboot. You can check whether your modification takes effect or not by "ulimit -n".

 

OK！问题解决

 

 

 Can I use a emulator to develop for AT91 devices?

 

A: Yes. The Android SDK provided a set of tools to run a customized image. Please see below the steps:

• After finish compiling Android4SAM you can find three .img files inout/target/product/sam9m10
  • system.img
    • The initial system image.
  • ramdisk.img
    • The ramdisk image used to boot the system
  • userdata.img
    • The initial user data image (see below)
  • kernel-qemu
    • The emulator-specific Linux kernel image

 If the kernel image is not found in the out directory, you may find it in/prebuilt/android-arm/kernel

• Copy those images in a directory.
• Use command to start a emulator based on our own images by typing following command:

 

 

    $ out/host/linux-x86/bin/emulator -kernel kernel-qemu -ramdisk ramdisk.img -system system.img -data userdata.img
