[Libunwind-devel] mips libunwind link failure

[Joe Damato]

Hi -

I am testing some code which links to libunwind on a mips system. I'm
an x86 guy and know nothing at all about mips.

uname -a:
Linux gcc42 2.6.27.1 #476 Tue Oct 20 14:25:23 CST 2009 mips64 GNU/Linux

I get the following error when trying to link to my application:

/home/joe/tmp/lib/libunwind-ptrace.a(_UPT_find_proc_info.o): In
function `get_unwind_info':
/home/joe/libunwind-0.99/src/ptrace/_UPT_find_proc_info.c:346:
undefined reference to `_UPTi_find_unwind_table'

Using nm on libunwind-ptrace.a I find:

_UPT_find_proc_info.o:
000001fc T _UPT_find_proc_info
         U _UPTi_find_unwind_table

Is this expected behavior? Maybe this part of MIPS support is not yet
implemented? Perhaps I built libunwind incorrectly?

Thanks for any hints about this.
