Here, I will describe two Ultrix setups: Ultrix 3.0 on an emulated Simh VAX and Ultrix 3.1 on a real MicroVAX 3100. The emulated VAX is a lot faster than the real VAX.

restoring Ultrix 3.1 on a MicroVAX 3100

copy image to harddisk using dd
boot in single user mode:
boot/r5:2 dkb100

fsck edit /etc/fstab
edit /etc/passwd
edit /etc/group
edit /etc/ttys
edit /etc/hosts
edit /etc/resolv.conf
edit /etc/rc.local
build new kernel to recognize additional disks.
doconfig, then choose to edit config file with vi.
disk rz2 at scsi0 drive 2 After building a new kernel, doconfig changes /etc/rc.local and uses the ident name of the kernel configuration as the new hostname. This might break things. Check and reset to a proper hostname. /etc/fstab /dev/rz9a:/:rw:49:1:ufs:: /dev/rz9g:/usr:rw:49:2:ufs:: /dev/rz9h:/usr/local:rw:98:3:ufs:: /dev/rz2a:/home:rw:98:4:ufs:: df Filesystem Total kbytes kbytes % node kbytes used free used Mounted on /dev/rz9a 19183 7323 9942 42% / /dev/rz9g 239663 129235 86462 60% /usr /dev/rz9h 233247 46743 163180 22% /usr/local /dev/rz2a 191958 72583 100180 42% /home The largest small 3.5" SCSI disk that is know by ULTRIX 3.1 is the RZ23.

setld -l /dev/rmt0h

build GNU stuff:


sh configure vax
make stage1
make CC=stage1/gcc CFLAGS="-g -O -Bstage1/"

do a make install. Trust this stage.

make stage2
make CC=stage2/gcc CFLAGS="-g -O -Bstage2/"
make CC="stage1/xgcc -Bstage1/" CFLAGS="-g -O"
make stage2
make CC="stage2/xgcc -Bstage2/" CFLAGS="-g -O"
make compare
make install

flex-2.5.4a scan.c want to include stdlib.h, which does not exists.

make check fails, because we have edited scan.c Trust and install anyway...

Ultrix 3.0:

add: typedef int size_t;


sed-1.18 bison-1.25

Ultrix 3.1: edit /usr/local/lib/gcc-include/stddef.h and remove definition of size_t Ultrix defines size_t in <sys/types.h> as "typedef int size_t;"

Ultrix 3.0 works fine.

make-3.75 m4-1.4 bash-1.14.7


ultrix 3 doesn't know about atexit().
#undef HAVE_ATEXIT before building gcc.
configure as vax-dec-ultrix3.1
then do a make bootstrap
gcc will use the host cc to build the first stage. This works.
You can also edit the Makefile and use gcc to build the first stage: CC = gcc


#include <sys/types.h>



uncomment: /* extern SPRINTF_RET sprintf P((char *, const char *, ...)); */
needs link with -lm
copy install-sh from gawk to /usr/local/bin/install

gcc headers:

there is something in sys/types.h that gcc-2.3.3 cannot compile.
Fix the "volatile" on line 80 ff and copy the custom header to the gcc include directory.



binutils/arlex.c: remove includes of stdlib.h
ld/ldlex.c: remove includes of stdlib.h
On Ultrix 3.0:
if there are any "size_t undeclared" error, include <sys/types.h>
make install will fail. Copy as to /usr/local/bin/gas and ld to /usr/local/bin/gnuld.


incorrectly includes stdlib.h in ../gcc-
on line 73.
--with-as=/usr/local/bin/gas --with-gnu-as --with-ld=/usr/local/bin/gnuld --with-gnu-ld
change Makefile: edit CC = cc to CC = gcc.
stage1 gcc cannot be build with VAX cc anymore.
Ultrix 3.0:

-c -DIN_GCC -O -g -I./include -I. -I.. -I/home/compile/gcc- -I/home/compile/gcc-

retry withouth gnu as: also fails...
Foor some reason, ULtrix 3 and 3.1 won't build gcc-


--with-as=/usr/local/bin/gas --with-gnu-as --with-ld=/usr/local/bin/gnuld --with-gnu-ld
change Makefile: edit CC = cc to CC = gcc
--with-as=/usr/local/bin/gas --with-gnu-as --with-ld=/usr/local/bin/gnuld --with-gnu-ld
change Makefile: edit CC = cc to CC = gcc
fails to build objc in stage1.
edit Makefile and remove objc from LANG


#include <sys/types.h>
#define NULL 0
do not strip the make binary. this breaks make.
function.c and job.c:
#ifndef remove
#define remove unlink


needs some #include <sys/types.h> in files that use size_t.


#include <sys/types.h>

Ultrix fopen() doesn't understand argument "wb".
Change to "w+"
add to pcre/pcre_globals.c:
#include <sys/types.h>
extern void *malloc(size_t);
extern void *realloc(void *, size_t);
extern void free(void *);
