Cross-Compiled Linux From Scratch - Version 3.0.0-SYSTEMD-Sparc64-Multilib

Chapter 10. Installing Basic System Software

10.62. Bash-4.3

The Bash package contains the Bourne-Again SHell.

10.62.1. Installation of Bash

The following patch contains updates from the maintainer. The maintainer of Bash only releases these patches to fix serious issues: 

patch -Np1 -i ../bash-4.3-branch_update-5.patch

The following sed points configure towards the correct library directory while searching for Readline: 

sed -i "/ac_cv_rl_libdir/s@/lib@&64@" configure

Prepare Bash for compilation: 

CC="gcc ${BUILD64}" CXX="g++ ${BUILD64}" \
    ./configure --prefix=/usr --bindir=/bin \
    --without-bash-malloc --with-installed-readline \
    --docdir=/usr/share/doc/bash-4.3

The meaning of the new configure option:

--with-installed-readline

This option tells Bash to use the readline library that is already installed on the system rather than using its own readline version.

Compile the package: 

make

To test the results, issue: 

make tests

Install the package: 

make install

Run the newly compiled bash program (replacing the one that is currently being executed): 

exec /bin/bash --login +h
[Note]

Note

The parameters used make the bash process an interactive login shell and continue to disable hashing so that new programs are found as they become available.

Short Descriptions

bash

A widely-used command interpreter; it performs many types of expansions and substitutions on a given command line before executing it, thus making this interpreter a powerful tool

bashbug

A shell script to help the user compose and mail standard formatted bug reports concerning bash

sh

A symlink to the bash program; when invoked as sh, bash tries to mimic the startup behavior of historical versions of sh as closely as possible, while conforming to the POSIX standard as well
