5.6. BusyBox-1.24.2
BusyBox combines tiny versions of many common UNIX utilities into a single small executable. It provides replacements for most of the utilities you usually find in GNU fileutils, shellutils, etc. The utilities in BusyBox generally have fewer options than their full-featured GNU cousins; however, the options that are included provide the expected functionality and behave very much like their GNU counterparts. BusyBox provides a fairly complete environment for any small or embedded system.
5.6.1. Installation of BusyBox
First ensure the BusyBox source is completely clean:
make distclean

Note
We tell BusyBox to use the generic defconfig. For those who are more adventurous, you can use make menuconfig, and create a custom or modified configuration for your build.
The following tells BusyBox to use the default configuration:
make ARCH="${CLFS_ARCH}" defconfig
Disable building both ifplugd and inetd as they both have issues building against musl:
sed -i 's/\(CONFIG_\)\(.*\)\(INETD\)\(.*\)=y/# \1\2\3\4 is not set/g' .config sed -i 's/\(CONFIG_IFPLUGD\)=y/# \1 is not set/' .config
Disable the use of utmp/wtmp as musl does not support them:
sed -i 's/\(CONFIG_FEATURE_WTMP\)=y/# \1 is not set/' .config sed -i 's/\(CONFIG_FEATURE_UTMP\)=y/# \1 is not set/' .config
Disable the use of ipsvd for both TCP and UDP as it has issues building against musl (similar to inetd's issues):
sed -i 's/\(CONFIG_UDPSVD\)=y/# \1 is not set/' .config sed -i 's/\(CONFIG_TCPSVD\)=y/# \1 is not set/' .config
Compile the package:
make ARCH="${CLFS_ARCH}" CROSS_COMPILE="${CLFS_TARGET}-"
Install the package:
make ARCH="${CLFS_ARCH}" CROSS_COMPILE="${CLFS_TARGET}-"\
CONFIG_PREFIX="${CLFS}/targetfs" install
If you're going to build your kernel with modules, you will need to make sure depmod.pl is available for your host to execute:
cp -v examples/depmod.pl ${CLFS}/cross-tools/bin
chmod -v 755 ${CLFS}/cross-tools/bin/depmod.pl
