Description Elmar Stellnberger 2009-05-13 10:29:22 UTC

User-Agent:       Mozilla/5.0 (compatible; Konqueror/3.5; Linux) KHTML/3.5.10 (like Gecko) SUSE

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;





Reproducible: Always

P.S.: This affects many different 32bit programs on x86_64-platforms like the Modula-3 compiler as well.

Comment 2 Elmar Stellnberger 2009-05-23 19:31:57 UTC

accidentially used wrong header files. Should however not be too difficult to provide a common header file and thereby a libbfd-32bit for x86_64 platforms since only the first few lines in bfd.h differ:

#define BFD_DEFAULT_TARGET_SIZE 32

#define BFD_HOST_64BIT_LONG 0
#define BFD_HOST_64BIT_LONG_LONG 1
#if 1
#define BFD_HOST_64_BIT long long
#define BFD_HOST_U_64_BIT unsigned long long

---------------------------------------------------

#define BFD_DEFAULT_TARGET_SIZE 64

#define BFD_HOST_64BIT_LONG 1
#define BFD_HOST_64BIT_LONG_LONG 0
#if 1
#define BFD_HOST_64_BIT long
#define BFD_HOST_U_64_BIT unsigned long

openSUSE 11.1 is out of support. As it is not easy to reproduce all the bugs please verify the latest release of openSUSE and open a new issue if you are still having the issue.
