[bproc]I need to help about Bproc-2.2.2.

[Orlando Rocha]

Hello, Erik:
Thanks and Sorry, I didn't explain well, but let me say:
Kernel: 2.2.14.5-0
Bproc: 0.2.1
My kernel was compiled with as follow modules:
BEOWULF DISTRIBUTED PROCESS SPACE
GHOST PROCESS SUPPORT
PROCESS ID MASQUERADING SUPORT
As per the install file:
Install:
* Step 1 - Patch your Linux kernel
  For example:
  $ cd /usr/src/linux
  $ patch -p1 < ~/bproc/patches/bproc-patch-2.2.x
  The patch provided is against linux-2.2.10.
* Configure your kernel
  Under "General Setup"
  Turn on all three:
    Beowulf Distributed Process Space Support
    Ghost Process Support
    Process ID Masquerading Support
* Rebuild your kernel
* Reboot
* Create bproc devices
  $ make devs
  This should create these 3 devices:
  crw-rw-rw-   1 root     root      10, 222 Mar 30 15:37 /dev/bproc_masq
  crw-rw-rw-   1 root     root      10, 223 Mar 30 15:37 /dev/bproc_ghost
  cr--r--r--   1 root     root      10, 224 Mar 30 15:37 /dev/bproc_iod
  (master needs ghost + iod device, slave needs masq device)
* Configure kernel modules
  Edit Makefile.conf so it agrees with your kernel configuration.  (This
  will be automated someday.)
* Build kernel modules, daemons and clients
  $ make
* Install kernel modules
  $ cd kernel
  $ make mods
When I did (make mods) look at:
$insmod vmadump.o
vmadump.o: unresolved symbol k_write_u
vmadump.o: unresolved symbol k_write
vmadump.o: unresolved symbol k_read_all_u
vmadump.o: unresolved symbol k_read_all
               .....
$insmod bproc_masq.o
bproc_masq.o: unresolved symbol bproc_next_req
bproc_masq.o: unresolved symbol bproc_next_req_wait
bproc_masq.o: unresolved symbol bproc_put_back_req
                .....

$insmod bproc_ghost.o
bproc_ghost.o: unresolved symbol k_close
bproc_ghost.o: unresolved symbol bproc_send_req
bproc_ghost.o: unresolved symbol k_listen

What could It be? How can I solve this problem?
Thanks a lot,
Orlando Rocha
