Looking at the section headers for one of the object files:
$ elfdump -h .libs/allocator-inst.o
.libs/allocator-inst.o:
**** SECTION HEADER TABLE ****
[No] Type Addr Offset Size Name
Link Info Adralgn Entsize Flags
[1] 0x11 0 0x34 0x8 .group
43 0x25 0x4 0x4 0x00000000
[2] 0x11 0 0x3c 0x8 .group
43 0x26 0x4 0x4 0x00000000
...
[13] SHT_PROGBITS 0 0xa0 0 .text
0 0 0x10 0 0x00000006 ALLOC EXECINSTR
[14] SHT_PROGBITS 0 0xa0 0 .data
0 0 0x10 0 0x00000003 WRITE ALLOC
...
Notice for some of the section headers, we get numbers for the type (e.g. 0x11)
rather than a name (SHT_PROGBITS). Is this the reason for the ld error? I'm
thinking the section types in the elfdump -h output get converted to names for
the types ld knows about and left as numbers otherwise.
According to <elf.h>:
#define SHT_NULL 0 /* sh_type */
#define SHT_PROGBITS 1
#define SHT_SYMTAB 2
#define SHT_STRTAB 3
#define SHT_RELA 4
#define SHT_HASH 5
#define SHT_DYNAMIC 6
#define SHT_NOTE 7
#define SHT_NOBITS 8
#define SHT_REL 9
#define SHT_SHLIB 10
#define SHT_DYNSYM 11
#define SHT_NUM 12 /* Number of sh_types, not an actual */
/* sh_type. */
/* SHT_NUM must be one greater than the
** highest sh_type value.
*/
I looked at .libs/allocator-inst.o from gcc-3.4.3 and didn't see the 0x11
section types.
