Chapter 6. Cross Compiling Temporary Tools

6.4. Bash-5.2.37

The Bash package contains the Bourne-Again Shell.

Approximate build time: 0.2 SBU
Required disk space: 67 MB

6.4.1. Installation of Bash

Prepare Bash for compilation: 

./configure --prefix=/usr                      \
            --build=$(sh support/config.guess) \
            --host=$LFS_TGT                    \
            --without-bash-malloc              \
            bash_cv_strtold_broken=no

The meaning of the configure options:

--without-bash-malloc

This option turns off the use of Bash's memory allocation (malloc) function which is known to cause segmentation faults. By turning this option off, Bash will use the malloc functions from Glibc which are more stable.

Compile the package: 

make

Install the package: 

make DESTDIR=$LFS install

Make a link for the programs that use sh for a shell: 

ln -sv bash $LFS/bin/sh

Details on this package are located in Section 8.36.2, “Contents of Bash.”
