Use Gdbserver to debug C programs in Android

First of all, this article may be flawed, because I do not have the conditions to test the dynamic library debugging. (mainly because it is their own mobile phones do not want to put all kinds of so)

So I can only say that if I have time, I will go to the test, this is the first.

1. Test Code GDB-TEST.C

#include <stdio.h>

int main () {

printf ("This is the GDB test!!! \ n ");

}

2, Android.mk

Local_path: = $ (call My-dir)

Include $ (clear_vars)

Local_cflags: =-G

Local_strip_module: = flase #禁止对最终生成的gdb-test for STRIP processing

Local_moule_tags: = Optional
Local_src_files: = gdb-test.c
Local_module: = Gdb-test
Include $ (build_executable)

3, copy gdb-test gdbserver to device Data directory (here just for simplicity)

4. Enter in the shell

# adb Shell

into the shell in device

# CD Data

#./gdbserver:2000./gdb-test (Note: Gdb-test can be sent here)

The port we used for Gdbserver was 2000.

If you succeed, you will see

# Listening on Port 2000

Description successfully opened the service

5, on the PC to perform

ADB forward tcp:2000 tcp:2000

6, in the running of the GDB on the PC, the specific path is

#arm-linux-androideabi-gdb./gdb-test

Note that the position of the gdb-test here is very important because you can see that there is a gdb-test under Libs, also under OBJ, in order to ensure that the symbol table

Can be successfully loaded, this must be used in the gdb-test under OBJ, because Libs is always generated by removing the symbol table, only the OBJS in the real can be debugged.

After successful entry into GDB, enter

# (GDB) Target remote:2000
