Chapter 25. SVR4-style Tools

heirloom-devtools-070527

Introduction to heirloom-devtools

The heirloom-devtools package provides the SVR4 versions of the yacc, lex, m4, make, and SCCS tools. Those tools are portable derivatives of the tools released as a part of OpenSolaris, which were derived from the original UNIX versions.

Installation of heirloom-devtools

Apply a patch to bring up the source to the last upstream commit: 

patch -Np1 -i ../heirloom-devtools-070527-final-updates.patch

Now, apply a patch to fix the compilation of the make utility: 

patch -Np1 -i ../heirloom-devtools-070527-fix-make-build.patch

Next, adjust the build configuration to use libtirpc: 

sed -i 's=-O=-O -I/usr/include/tirpc=g' mk.config

If you have heirloom-sh installed, execute the following commands to tell heirloom-devtools where to find it: 

sed -i 's-/sbin/sh-/usr/5bin/sh-g' mk.config &&
sed -i 's-/bin/sh-/usr/5bin/sh-g' mk.config &&
sed -i 's-/bin/sh-/usr/5bin/sh-g' sccs/src/sccsdiff.sh

Otherwise, execute the following command to use the normal 'sh': 

sed -i 's-/sbin/sh-/bin/sh-g' mk.config

Important

Ensure you are building this package as an unprivileged user and NOT as the root user, or else the make process will fail as it will be unable to create a temporary file/directory.

Install heirloom-devtools by running the following command: 

CC="cc -std=gnu17" make -j1

Now, as the root user: 

make install

Command Explanations

make -j1: This command builds the package using only one thread to ensure there is no race condition.
