https://bugzilla.novell.com/show_bug.cgi?id=778662 https://bugzilla.novell.com/show_bug.cgi?id=778662#c8 --- Comment #8 from Andreas Jaeger 2012-09-05 13:39:16 UTC --- sysdeps/unix/sysv/linux/dl-origin.c implements the search via: /* On Linux >= 2.1 systems which have the dcache implementation we can get the path of the application from the /proc/self/exe symlink. Try this first and fall back on the generic method if necessary. */ len = INTERNAL_SYSCALL (readlink, err, 3, "/proc/self/exe", linkval, sizeof (linkval)); if (! INTERNAL_SYSCALL_ERROR_P (len, err) && len > 0 && linkval[0] != '[') { /* We can use this value. */ ... /* We use the environment variable LD_ORIGIN_PATH. If it is set make a copy and strip out trailing slashes. */ if (GLRO(dl_origin_path) != NULL) That's the difference... I don't consider this a bug - the bug is that /proc is not mounted. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
