            I know this has been discussed before,  cuz I've searched,
but I'm stumped.

            I got Busybox V1.0 and I got 'unresolved symbols' from my
insmod.

 

>From Kernel config

 

  [*] Enable loadable module support                           x x  

  x x        [ ]   Set version information on all module symbols
x x  

  x x        [*]   Kernel module loader
x x  

  x x                                      

 

Just to confirm:

 

ave-lab-52 linux-2.4.20 # grep MODVERS .config

27:# CONFIG_MODVERSIONS is not set

ave-lab-52 linux-2.4.20 # grep MODVERS include/linux/autoconf.h 

28:#undef  CONFIG_MODVERSIONS

 

>From busy box config

/ # insmod mymod.o

insmod: /lib/modules/2.4.20-rmk2-ds3-kdb-svos: No such file or directory

Using /lib/modules/mymod.o

insmod: unresolved symbol pci_write_config_byte

insmod: unresolved symbol pci_dev_driver

insmod: unresolved symbol pci_insert_device

insmod: unresolved symbol pci_setup_device

insmod: unresolved symbol pci_register_driver

insmod: unresolved symbol pci_remove_device

insmod: unresolved symbol pci_enable_device

insmod: unresolved symbol pci_read_config_byte

insmod: unresolved symbol pci_read_config_dword

insmod: unresolved symbol pci_read_config_word

insmod: unresolved symbol pci_match_device

insmod: unresolved symbol pci_assign_resource

insmod: unresolved symbol pci_root_buses

insmod: unresolved symbol pci_devices

insmod: unresolved symbol pci_unregister_driver

insmod: unresolved symbol pci_write_config_dword

insmod: unresolved symbol pci_write_config_word

insmod: unresolved symbol printk

/ #

 

 

On the target system:

/ # cat /proc/ksyms | grep printk

80050a9c fp_printk

80050a9c printk_R__ver_printk

/ #

 

All the pci_xxx symbols are followed by the versioning like printk.

I _DID_ use 'extern's on 'em.

 

So why are the symbols versioned?

 

Is this my problem?

Thanx,

 Dan
