I need an help!! I am trying to build a standalone executable ie without ANY dynamic linking.
I wrote a small test program, generated a relocatable object file for it called test.o. When I try to build the standalone executable using GNU linker I get the below error:
$ld -static -o test test.o /usr/lib/crt1.o /usr/lib/crti.o /usr/lib/libc.a /usr/lib/gcc/i486-linux-gnu/4.4/libgcc.a /usr/lib/gcc/i486-linux-gnu/4.4/libgcc_eh.a
/usr/lib/gcc/i486-linux-gnu/4.4/libgcc_eh.a(unwind-dw2-fde-glibc.o): In function _Unwind_Find_FDE':
(.text+0x190b): undefined reference to
dl_iterate_phdr'
How to resolve the undefined symbol dl_iterate_phdr. In which archive this symbol is present?
Thanks!!!
EDIT1:
Just in case if I am not very clear, my motive is to generate a standalone executable ie an executable which is completely ready for execution while it gets loaded into memory i.e.) all symbol resolution and relocation is done by program linker itself instead of dynamic linker. Is it possible to generate such an executable?
FINAL UPDATE:
Now I got it to get complied with ld directly using the below command:
$ld -static -o test /usr/lib/crt1.o /usr/lib/crti.o /usr/lib/gcc/i486-linux-gnu/4.4.3/crtbeginT.o /usr/lib/gcc/i486-linux-gnu/4.4.3/crtend.o test.o --start-group /usr/lib/gcc/i486-linux-gnu/4.4.3/libgcc.a /usr/lib/gcc/i486-linux-gnu/4.4.3/libgcc_eh.a /usr/lib/libc.a --end-group
man ld says --start-group archives --endgroup is used to resolve circular references!! Also i find symbol dl_iterate_phdr is defined in libc.a.
Thanks all for your help!!
