Using the addr2errline sample program from
http://linuxgazette.net/151/misc/melinte/addr2line.c
I get the following results:
> gcc addr2errline.c -o addr2errline -lbfd -liberty -lz
> ./addr2errline getlineno 0x804b335 0x804b2aa
main [getlineno.c:61]
ThisLine [getlineno.c:49]
> gcc -m32 addr2errline.c -o addr2errline -lbfd -liberty -lz
> ./addr2errline getlineno 0x804b335 0x804b2aa
> ** no result, nothing found, 0 lines of output **
It does not depend on the library version. If I link against old 32bit bfd &
liberty librays from x86_32 days of OpenSuse10.1 it does not work either.
Perhaps this is some general incompatibility of 32/64bit plattforms.
Debugging addr2errline.c I found that the error turns out at the following
point:
slurp_symtab(bfd *abfd)
{
...
if ((bfd_get_file_flags(abfd) & HAS_SYMS) == 0)
return -1;
