Chapter 6. Installing Basic System Software

6.41. Psmisc-22.3

The Psmisc package contains programs for displaying information about running processes.

6.41.1. Installation of Psmisc

Prepare Psmisc for compilation: 

./configure --build=${CLFS_HOST} --host=${CLFS_TARGET} \
    --prefix=/usr --exec-prefix=""

The meaning of the configure option:

--exec-prefix=""

This ensures that the Psmisc binaries will install into /bin instead of /usr/bin. This is the correct location according to the FHS, because some of the Psmisc binaries are used by the CLFS-Bootscripts package.

Compile the package: 

make

Install the package: 

make DESTDIR=${CLFS} install

There is no reason for the pstree and pstree.x11 programs to reside in /bin. Therefore, move them to /usr/bin: 

mv -v ${CLFS}/bin/pstree* ${CLFS}/usr/bin

By default, Psmisc's pidof program is not installed. This usually is not a problem because it is installed later in the Sysvinit package, which provides a better pidof program. If Sysvinit will not be used for a particular system, complete the installation of Psmisc by creating the following symlink: 

ln -sv killall ${CLFS}/bin/pidof
