The BL1 site linked to BL3 site lists what you need for BL1 (libc5, 
Slackware 3 or 4) but the packages are different for Slackware 8.1.
Steven, can you list them at the BL3 site as a link?
It took me a long time for find the info again.

For Slackware 7 you need egcs or gcc, binutils, gmake, linuxinc and glibc.

Slackware 8.1 (which uses long file names and bigger packages) uses 
gcc*2.95.3*.tgz, binutils*.tgz, make*.tgz, kernel-headers*.tgz, and glibc* 
make-3.79.1*tgz

I owe a LOT of help.  Other people compiled all sorts of stuff for BL and 
for me personally.

pwd is in busybox (big surprise).

Many of the other busybox commands are already linked to /bin but
this was omitted.

ln -sf /bin/busybox /bin/pwd
(if it is /bin/busybox - I forget where BL3 busybox resides.)

I have a /usr/include/linux-2.4.31/include/linux/string.h and ctype.h but 
not error.h or fntctl.h of stdio.h or sys/types.h.

When I compile I do 'make config' and 'make dep' and 'make bzImage' and 
'make modules' in that order.  I don't know how to compile just one module 
or if you need the other steps first.  You could try skipping the make 
bzImage (kernel) step.  It can take 20 min at 200MHz.

Try upgrading binutils etc. and then compile again, doing all the above.
Make dep might tell the compiler where to look for things.
(But I don't even find the files you are missing, on my computer).

Maybe.  Upgrade and try again.  Slackware 4 probably does not even include 
iptables (in ipv4), so probably you are missing some pieces.

I don't understand how compiling works, just try to follow instructions 
and blunder through.  I had help getting started.

make consults Makefile and instructs gcc what to do.
Smaller programs can just be compiled CLI with gcc.
C++ programs need an additional library (cxx or cpp).

There was a long discussion about using BL3 this way.

Search the archives on ipchains or 'gateway between two laptops'.
circa 2008.  iptables replaced ipchains in kernel 2.4 (you had a choice 
of both).  SW41 does not have iptables, only ipchains.

Steven worked out a very simple solution that let me share my dialup 
connection between two computers.

See gw-on and ip-on scripts at my site, which use ipchains and set default 
gateway.  I also posted ipchains-glibc21.gz - unzip and rename it 
ipchains.  My vsp desktop kernel has the ipchains driver compiled in 
already so you don't need ipchains.o.  So does the BL3 'big' kernel.

3c59x is my NIC module.  Substitute your NIC module(s).

ip-on

Run on the gateway ('big' or bare.i kernel or my 2.4.31 bzimavsp.431),
and gw-on on other computers (different IP number for each - 2, 3, etc.)

echo 1 > /proc/sys/net/ipv4/ip_forward
insmod 3c59x
ifconfig eth0 192.168.1.1
ipchains -P forward DENY
ipchains -A forward -s 192.168.1.0/24 -j MASQ


gw-on

insmod 3c59x
ifconfig eth0 192.168.1.2
route add default gw 192.168.1.2
