Hello! I am trying to link the compiled source of FreeBSD 7 with gcc, which always fails to find the symbols '__start_set_sysinit_set' and '__stop_set_sysinit_set'. The compiler is gcc version 4.1.2, for amd64 target. There is very little on the web about these symbols. What I managed to find out, that these are put together by C macros and in the end, are defined as extern structures. There are no implementations behind them. But for i386, using gcc version 3.2.3 I have managed to compile and link the source, without any problems. I have compared the object files and it seems, that a whole lot symbols are missing from the symtab. Especially objects starting with "__set_sysinit_set_sym_" . You can have look at the source file here: http://fxr.watson.org/fxr/source//kern/init_main.c?v=FREEBSD7 The generated object's symtab were made with 'objdump -t' . (Attached outputs i386: objd_i386, amd64: objd_amd64). Some of the missing symbols are: 0000018c l O .data 00000010 placeholder_sys_init 00000000 l d set_sysinit_set 00000000 set_sysinit_set 00000000 l O set_sysinit_set 00000004 __set_sysinit_set_sym_placeholder_sys_init These should be generated according to code. The symbols in the error message are listed undefined for both architectures: i386: 00000000 *UND* 00000000 __start_set_sysinit_set 00000000 *UND* 00000000 __stop_set_sysinit_set amd64 0000000000000000 *UND* 0000000000000000 __start_set_sysinit_set 0000000000000000 *UND* 0000000000000000 __stop_set_sysinit_set I also noticed a line which appears only with amd64: 0000000000000000 l d .note.GNU-stack 0000000000000000 .note.GNU-stack Can please someone tell me what I might do wrong? Why are symbols missing? Thanks in advance.
