Subject:Re[2]: dlinfo() from sunOS, _DYNAMIC from Linux: did we have something like this?

Hi,

Actually, the FreeBSD linker does put _DYNAMIC int executables, it's just not
declared in any headerfile, so I assume some config script isn't picking it up. You can
declare it as

#include <elf.h> extern Elf_Dyn DYNAMIC[];

(The FreeBSD ELF headers will typedef Elf_Dyn from either Elf32_Dyn, or
Elf64_Dyn, depending on your platform.) To hack the offending code into working, you could
do something like this at the top.

#ifdef __FreeBSD__ #include <elf.h> extern Elf_Dyn DYNAMIC[];

#undef HAVE_DECL__DYNAMIC #undef HAVE_ELF32_DYN #undef HAVE_ELF64_DYN

#define HAVE_DECL__DYNAMIC 1 #if __ELF_WORD_SIZE == 32 #define HAVE_ELF32_DYN 1 #define HAVE_ELF64_DYN 0 #else #define HAVE_ELF64_DYN 1 #define HAVE_ELF32_DYN 0 #endif

.. and cross your fingers before compiling.
