用gdb调试 android webkit

用gdb调试webkit

参考：http://source.android.com/porting/debugging_gdb.html，直接看这一段Detailed Instructions

启动模拟器

$emulator

进入device

$adb shell

从模拟器点击启动Browser

看看它的process id是多少

#ps

记住你要的pid

启动gdbserver，指定在哪个prot上监听client，指定调试哪个进程

#gdbserver :5039 --attach pid

开始cient端的工作

On your workstation, forward port 5039 to the device with adb: 不知道怎么翻译

打开一个新的终端

$adb forward tcp:5039 tcp:5039

$cd ~/mydroid

找一个最新版本的arm-eabi-gdb

$find -name arm-eabi-gdb

记住path

启动gdbclient

$/home/peipei/mydroid/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi-gdb /home/peipei/mydroid/out/target/product/generic/symbols/system/bin/app_process

In gdb, Tell gdb where to find the shared libraries that will get loaded:

(gdb)set solib-absolute-prefix /home/peipei/mydroid/out/target/product/generic/symbols

(gdb)set solib-search-path /home/peipei/mydroid/out/target/product/generic/symbols/system/lib

小心，路径别写错，如果错了，gdb是不会告诉你的。

另外，要注意，两个路径都要指向symbols目录。

Connect to the device by issuing the gdb command:

(gdb)target remote :5039

The :5039 tells gdb to connect to the localhost port 5039, which is bridged to the device by adb.

You may need to inspire gdb to load some symbols by typing:

(gdb)shared
