Hi,
We are trying to upgrade UREP to 3.2 under Ultrix 2.2 running on VAX 11/785.
We encountered problems and couldn't make it. Followings are the steps
we did. Would some one tell me how to solve it.
1. Added "device dup0 at uba0 csr 0160050 vector duprint dupxint" to
/sys/conf/NOTE file.
2. Added "dup 54" to /sys/conf/devices.vax
3. Deleted "vaxif/if_dup.c optional dup device-driver Binary"
from /sys/conf/files.vax to avoid duplicate declaration
of dupprobe(), dupopen(), dupclose(),... to vaxuba/dup.c.
4. Added "vaxuba/dup.c optional dup device-driver NotBinary Unsupported"
to /sys/conf/files.vax.
5. Copied urep3.2/4.2dup.c to /sys/vaxuba/dup.c.
6. Copied urep3.2/*.h file to corresponding directory.
7. Added urep3.2/CONF.c to /sys/vax/conf.c
8. Added "dupopen, dupclose, dupread, dupwrite, /* 54 */
nodev, nodev, nodev, 0,
seltrue, nodev, 0 "
to cdevsw[] of /sys/vax/conf.c.
9. Config NOTE
10. make depend
11. make vmunix
12. mknod dup0 c 54 0 /* make device /dev/dup0 */
13. chmod 666 /dev/dup0
14. cp vmunix /vmunix
15. Shutdown system
16. Reboot system with new vmunix
"dup0 at uba0 csr 160050 vec 300, ipl 15" printed on console.
17. started daemon
18. netexec -W gwuvm start
error message "Can't open /dev/dup0"
19. cat > /dev/dup0 /* check device */
"No such device or address"
20. Checked README.ULTRIX and mail from Alan Crosswell

21. Deleted "register int br, cvec; " from /sys/vaxuba/dup.c.
22. Config NOTE; cd /sys/NOTE; make depend; make vmunix
got compile error message:
"dup.c: line 173 "cvec" undefined"
23. Added "int cvec;" to /sys/vaxuba/dup.c before main() to make it
as global variable according to Alan's mail.
24. Successfully generated dup.o to BINARY.vax/dup.o
25. linked vmunix and got following error message:
loading vmunix
Undefined:
_spl6
_spl0
Stop.
Thanks in advance!
