Following the instructions in noweb/src/INSTALL:
$ cd noweb/src
$ ./awkname awk # openbsd uses awk, not nawk
Now the right awk will be used.
The next step is to set environmental variables for the build process. In
the INSTALL file, the author recommends to use a script and not to
modify Makefile directly. Modifying the Makefile is faster, so,
the variables to change are:
# Adjust these two lines for your ANSI C compiler
# changed gcc to cc since openbsd 7.1 uses clang by default
CC=cc -ansi -pedantic -O -Wall -Werror
CFLAGS=
# BIN is where the commands (notangle, noweave, nountangle, noroots) land
# LIB is where the pieces of the pipes (nt, markup, unmarkup) are stored
# MAN is the root of your local man pages directory
# MANEXT is the extension for your commands' man pages (usually 1 or l)
# MAN7EXT is the extension for the nowebstyle man page (usually 7)
# TEXINPUTS is the directory for TeX macro files
# ELISP is the directory for emacs lisp files, or /dev/null not to install
BIN=/home/ncb/bin
LIB=/usr/local/noweb/lib
MAN=/usr/local/noweb/man
MANEXT=1
MAN7EXT=7
TEXINPUTS=/home/ncb/bin/tex/inputs
ELISP=/dev/null
To install, first issue (in noweb/src/):
$ make boot # to prevent using noweb to build noweb
$ make all install # build and move files to the right places
To clean some generated files
$ make clean
