print stack trace in arm-linux

问题

I followed this post to print stack trace How to generate a stacktrace when my gcc C++ app crashes . It works well in x86 linux. Can anyone teach me how to make it work on arm-linux?

I am using arm-linux-gcc 4.4.3.

[root@FriendlyARM /]# ./test1
Error: signal 11:
[0x0]

in x86

mickey@mickeyvm:~/Desktop/workspace/test/testCatchSeg/src$ ./test1
Error: signal 11:
./test1(_Z7handleri+0x19)[0x804876d]
[0xedd400]
./test1(_Z3bazv+0x10)[0x80487c2]
./test1(_Z3barv+0xb)[0x80487e1]
./test1(_Z3foov+0xb)[0x80487ee]
./test1(main+0x22)[0x8048812]
/lib/i386-linux-gnu/libc.so.6(__libc_start_main+0xe7)[0x84de37]
./test1[0x80486c1]

This is how I compile for arm-linux

 arm-linux-g++ -g -rdynamic ./testCatchSeg.cpp -o testCatchSeg

回答1:

ARM does not store the return address on the stack when branching to a subroutine but rather expects any function calling subroutines to save the link register to its own stack frame before calling other functions, so it is impossible to follow stack frames without debug information.

I just got backtrace() to work with GCC for ARM. The key for me was compiling with -funwind-tables. Otherwise the stack depth was always 1 (i.e. empty).
