Don't omit the details: How precisely did you run configure? In what directory is this error occurring? Please check HAVE_GETIPINFO in libbacktrace/config.h. I assume it is 1. It looks like you may be doing some sort of Canadian Cross build. What version of GCC is i686-unknown-linux-gnu-gcc? Does that version of gcc declare _Unwind_GetIPInfo in its unwind.h? Does it provide _Unwind_GetIPInfo in its libgcc? Ian
