This is the output from a 'readelf -a /bin/ls'. It is the cause of the dynamic linker problem (glibc 2.5 or later). By allowing /bin/ld write this into the ELF executable, the /lib/ld-linux.so.2 does not like it on the older systems. Additionally, we are missing a ".hash" ELF section, but the above is a trigger. I have a tool which removes the .gnu.hash section and adds a .hash section. Whilst the above .dynamic entry exists, it doesnt know what I did. Additionally, gdb gets confused too. Next step is to polish off the code so it can create a fully conforming/working ELF executable, and its ready to roll. (In case you didnt follow any of this, how to create an executable on Linux which runs on any release of Linux/glibc. Later Linux distros dont create backward compliant executables leading to an arms race of platform and version specific releases which is a waste of everyones' effort).
