If you also have etc01 installed and  all you want is to install the
patch kit, it is very easy (otherwise you currently need to selectively
apply patches that don't patch etc01 stuff...).  I'll assume that you
have seen Terry Lambert's FAQ and Nate William's FAQ (both on agate and
gatekeeper).

Install the _whole_ kit (iALL - currently 58 patches ) as per the
instructions.  Some patches cause problems on some systems, hopefully
yours it not one of them...  Ignore Terry's warning because you have to
put an option line in your config file to enable code like the Danpex
patch.  You might want to first recompile /usr/src/bin/csh since
it crashes  easily as distributed:


# su
# cd /usr/src/bin/csh && make && make install
# exit	<=== re-login with new csh
# su
# cd /usr/src/usr.sbin/config
# make && make install
# cd /usr/src/sbin/init
# vi init.c

[add a semicolon at end of line 234, so it reads: 
"while (wait(&status) != pid);"]

# make && make install

# cd /sys/i386/conf
# vi GENERICISA    <=== or use SYSTEM_NAME

[change com1 to com0 and com2 to com1 - I also change IO_COM[12]  to
IO_COM[01]  here and in /sys/i386/isa/isa.h as well (?) 
To run X, add "options XSERVER" near  the top; you might also want to
increase the number of pty's (one per xterm).
To use the kernel debugger, add the line: "pseudo-device ddb"]

# config GENERICISA  
# cd /sys/compile/GENERICISA
# make depend
# make
# cp 386bsd /386bsd.pl58
# mv /386bsd.pl58 /386bsd
# cksum 386bsd /386bsd  <=== verify copied OK
# chown root /386bsd
# chgrp wheel /386bsd
# chmod 755 /386bsd
# sync; sync
# shutdown -r now
# cd /sys/compile/GENERICISA
# make clean
# make    <===  recompile to correctly install the math_emulate.c patch (?)
# cp 386bsd /386bsd.pl58
# mv /386bsd.pl58 /386bsd
etc and reboot

At this point, might want to look at /sys/ROADMAP.  You should also
rebuild /usr/src.  Adrian Hall's procedure (below)  works for me.  If
in addition you fix the HUGE constant in math.h from 1e500 to:

#define HUGE_VAL      1.79769313486231570e+308

you can recompile awk.  Hope that's all...

Subject: Getting /usr/src to compile on 386BSD
Date: 23 Sep 92 22:13:10 GMT
Organization: The IBM PC User Group, UK.

This is a list of things I had to do so that make works from /usr/src.
It is not comprehensive, and by no means authoritive, and not in any
particular order. You are advised to read the entire list if you are
going to use it.

        (1)        Remove the references to lib and include in
                /usr/src/Makefile. They need to be made before
                the programs, so either put them at the start or
                remove them.

        (2)        Edit /usr/share/mk/*.mk so that install does
                a install -c instead of an install without a
                -c. You will find re-compiles a whole lot quicker :)

        (3)        Do not re-compile libg++, g++, gcc, gas, gdb or
                groff. (1) Its a waste of time, and (2) they come
                up with errors when you compile them. (e.g. try
                
        (cd lib/libg++ ; make depend ; make ; make install)

                to see what I mean).

[These seem to compile OK if you don't run make depend, but I don't
know the implications of not doing so... -AM]

        (4)        Similarly, dont compile tn3270. It has bugs in
                the makefiles that I dont want to fiddle with,
                and there are no patches to it (yet.)

[Again, seems to compile if you don't run make depend and change
reference in api/makefile from <386bsd.lib.mak> to <bsd.lib.mak> -AM]

        (5)        When doing a 'make depend', keep it in the
                foreground, since when it comes to 'expr', you
                have to press ctrl-D to get it to continue.

        (6)        BEFORE DOING ANYTHING, type the following line :-

mkdir -p `find /usr/src -exec ls -l {} \; | awk '{print $10}'`

                This makes all the obj directories that are missing.

        (7)        You need to link /usr/include/vm to /sys/vm in order
                to compile ktrace (and possibly a couple of others).

        (8)        I also moved all manual pages to /usr/share/man/man*
                and removed the manual page creation stuff from the
                /usr/share/mk/* files. You can then use catman (grabbed
                from one of the /usr/othersrc/public catman files and
                slightly modified) to create the cat* files if you so
                desire. If you are short on space, this might be a good
                idea.

        (9)        Dont forget to add in netstat and tset to the list

[netstat is installed by the patch kit, but not tset - get this from
agate, for instance - AM]

                of subdirs in usr.bin/Makefile to get these made as
                well (The sources are on agate in one of the unofficial
                subdirectories).

        (10)        Dont forget to apply all the patches :)

        (11)        I got the message 'Program cc1 got fatal signal 6.'
                when compiling awk, so I left that out as well. If
                anyone has a fix for this, let me know, and I will
                put it in.

[The math.h patch above fixes this -AM]

        (12)        Make sure you have put in the DES code if you
                want it in (/usr/386bsd.errata/crypt.instructions
                explains how to get the crypt code into your library.
                Remember you are going to be re-compiling it though!).

Once all these have been done, it is a case of typing :-

        cd /usr/src
        make depend                (go get a pizza, preferably in
                                 another coutry).
        make                        (go get another pizza, preferably 
                                 on another continent).
        make install                (see make depend).

On my system, crond and crontab came up with lots of warnings. They
dont seem to have suffered as a consequence, so I guess you can 
ignore them.

        How rachel.ibmpcug.co.uk anonymous ftp is laid out.

I have put my entire source tree and share tree up for anonymous ftp.
In addition my current kernel (all drivers included and fully patched),
and configuration are in the top level directory. Anything that I have
installed for local use is kept in src/local (sources only).
If you think looking at any other files will be useful, please let me know.

A dist.fs and fixit.fs with fully patched kernels will appear sometime
in the very near future.
