Yeah.. :-(

Indeed.

Complete guesswork from nm -l /usr/lib64/libpci.a, this
is the object module where __res_query() is referenced:
names-net.o:
0000000000000000 r .LC0
000000000000000b r .LC1
0000000000000072 r .LC10

000000000000004d r .LC7
000000000000005e r .LC8
0000000000000064 r .LC9
U _GLOBAL_OFFSET_TABLE_
U __h_errno_location
U __memcpy_chk
U __res_init
U __res_query
U __sprintf_chk
U __stack_chk_fail
U __strdup
0000000000000000 t dns_skip_name
U pci_get_param
0000000000000060 T pci_id_net_lookup
0000000000000000 b resolver_inited.6042
Now that defines pci_id_net_lookup, and that appears
to be referenced here:
names.o:
0000000000000000 r .LC0
0000000000000003 r .LC1
0000000000000028 r .LC10
000000000000004f r .LC11
0000000000000054 r .LC12
000000000000005b r .LC13
0000000000000062 r .LC14
000000000000006c r .LC15
000000000000007b r .LC16
0000000000000081 r .LC17
0000000000000086 r .LC18
000000000000008c r .LC19
000000000000000e r .LC2
0000000000000092 r .LC20
0000000000000098 r .LC21
000000000000009e r .LC22
00000000000000a6 r .LC23
00000000000000b1 r .LC24
000000000000001a r .LC3
0000000000000029 r .LC4
000000000000002f r .LC5
0000000000000039 r .LC6
0000000000000000 r .LC7
0000000000000046 r .LC8
000000000000004e r .LC9
U _GLOBAL_OFFSET_TABLE_
U __snprintf_chk
U __sprintf_chk
U __stack_chk_fail
0000000000000160 t format_name
0000000000000000 t format_name_pair
0000000000000250 t id_lookup
0000000000000380 t id_lookup_subsys
U pci_id_cache_dirty
U pci_id_cache_load
U pci_id_insert
U pci_id_lookup
U pci_id_net_lookup
U pci_load_name_list
0000000000000460 T pci_lookup_name
U pci_mfree
U snprintf
That defines pci_lookup_name() and that is called from
hwloc here:
$ grep -R pci_lookup_name .
./src/topology-libpci.c:/* starting from pciutils 2.2, pci_lookup_name() takes
a variable number
./src/topology-libpci.c: resname = pci_lookup_name(pciaccess, name,
sizeof(name),
./src/topology-libpci.c: resname = pci_lookup_name(pciaccess, name,
sizeof(name),
./src/topology-libpci.c: resname = pci_lookup_name(pciaccess, name,
sizeof(name),
So my guess it's the fact that we only have a static
library that's causing the linker to pull in all the
symbols, whether needed or not. :-(
cheers!
