arm-linux-gdb 环境搭建及调试core文件

系统环境：

host：ubuntu12.04

gcc：gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5)

target:hisi3520d开发板

arm-linux-gcc：SDK中自带的arm-hisiv100nptl-linux-gcc

gdb版本：gdb-7.9

GDB环境搭建

解压gdb-7.9.tar.gz

编译gdb

# cd gbd-7.9

#./configure --target=arm-hisiv100nptl-linux --prefix=$PREFIX

# make

# make install


编译gdb_server

# cd gdb/gdbserver

#./configure --target=arm-hisiv100nptl-linux --host=arm-hisiv100nptl-linux --prefix=$PREFIX

# make

# make install
提示错误：/home/gdb-7.9/missing: line 81: makeinfo: command not found
WARNING: 'makeinfo' is missing on your system.
         You should only need it if you modified a '.texi' file, or
         any other file indirectly affecting the aspect of the manual.
         You might want to install the Texinfo package:
        
         The spurious makeinfo call might also be the consequence of
         using a buggy 'make' (AIX, DU, IRIX), in which case you might
         want to install GNU make:
        
按装库：apt-get install textinfo即可

在安装目录下bin目录生成文件：

arm-hisiv100nptl-linux-gdb  arm-hisiv100nptl-linux-gdbserver  arm-hisiv100nptl-linux-run

GDB调试

在开发板上执行arm-hisiv100nptl-linux-gcc编译生成的代码test，生成core文件，发现core文件大小为0字节。

原因：test文件放在虚拟机上，挂载到开发板上运行导致的，将test拷贝到开发板上就好了。

将开发板上生成core文件拷贝到虚拟机上，将test文件也拷贝到虚拟机上，放在同一目录下。在虚拟机上执行下面命令：

# arm-hisiv100nptl-linux-gdb test core

提示：

For help, type "help".
Type "apropos word" to search for commands related to "word"...
Reading symbols from bsjgui...(no debugging symbols found)...done.
BFD: Warning: /home/nfs/core is truncated: expected core file size >= 54865920, found: 2793472.

发现core文件被剪切了，发现是开发板上的磁盘空间不足导致的，删除开发板上的文件，腾出空间后正常。

重新执行命令：

# arm-hisiv100nptl-linux-gdb test core

提示如下：

warning: Could not load shared library symbols for 12 libraries, e.g. /dvr/ybq/lib/libz.so.1.
Use the "info sharedlibrary" command to see the complete listing.
Do you need "set solib-search-path" or "set sysroot"?
Core was generated by `./bsjgui'.
Program terminated with signal SIGABRT, Aborted.

设置所有的库路径：set solib-search-path /home/nfs/lib:/home/3520D_fs/rootfs/lib/:/home/share/Hi3520D_SDK_V1.0.3.0/mpp/lib
然后执行命令：

# core-file （清除core文件）

# core-file /home/nfs/core （重新导入core文件）

# bt（查看栈数据）

(gdb) bt
#0  0x401b0ba8 in ?? ()
#1  0x401b415c in ?? ()
Backtrace stopped: previous frame identical to this frame (corrupt stack?)

还是不能正常显示，设置绝对路径： set solib-absolute-prefix /home/nfs/lib:/home/3520D_fs/rootfs/lib/:/home/share/Hi3520D_SDK_V1.0.3.0/mpp/lib

然后继续操作：

gdb) bt

还是存在一条信息没有正常显示出来，跳过没有管
