我的程序crash,有了coredump文件,在Linux PC上用arm-linux-gdb debug it. The result is:
#0 0x4022b178 in ?? ()
(gdb) bt
#0 0x4022b178 in ?? ()
#1 0x4022b134 in ?? ()
#2 0x4022b134 in ?? ()
Backtrace stopped: previous frame identical to this frame (corrupt stack?)
(gdb)
why? I can't locate the correct location, find the really reason.
看看加载的内容

一些库找不到(/lib/libstdc++.so.6),或者版本不匹配。我不应该加载/lib/libdl..so.... 这些文件,这是针对X86的。
所以两个命令至关重要:
set solib-absolute-prefix -- Set prefix for loading absolute shared library symbol files
set solib-search-path -- Set the search path for loading non-absolute shared library symbol files
比如:set solib-... /usr/local/arm-linux/arm-linux/lib/, 两个参数的值一样就可以了。
先启动arm-linux-gdb,设置变量以后,via core-file load core dump file to analyze it.
#gdb
#set solib-absolute-prefix "library path"
#set solib-search-path "library path"
#file file.debug
#core-file core.1234
但是还是不能准确定位,查询embedded linux版本:
uname -a
ls -l /usr/arm-linux/gcc-3.4.1-glibc-2.3.3/arm-linux/lib/libc-2.3.3.so
Linux PC上的呢:
ll /usr/local/arm/3.4.1/arm-linux/lib/libc-2.3.2.so
原来库文件不对,一个是2.3.3,另一个是2.3.2,此时发现版本匹配是至关的重要啊!!
换了一个Linux PC,它的交叉编译环境是2.3.3
哈哈!立即定位到了错误的原因!!

一.关于gdb调试core文件总是一堆问号的问题
问题描述:已经在编译选项中加入了-g,但是查看core文件时,还是一堆问号,使用的命令为:gdb -c core
解决方案:由于gdb -c core这样的使用在有些系统下支持不是很好,所以推荐用如下两种方法:
1)gdb exe
(gdb) core-file core
2)gdb -c core
(gdb) file exe
而其中第二种方法在某些系统上也是不好用的,所以就用第一种即可。
