The Psmisc package contains programs for displaying information about running processes.
This package requires compiler variables to be set for the target in the environment.
export CC="${CLFS_TARGET}-gcc"
export CXX="${CLFS_TARGET}-g++"
export AR="${CLFS_TARGET}-ar"
export AS="${CLFS_TARGET}-as"
export RANLIB="${CLFS_TARGET}-ranlib"
export LD="${CLFS_TARGET}-ld"
export STRIP="${CLFS_TARGET}-strip"When cross-compiling the AC_FUNC_MALLOC
macro will assume that the malloc provided is not GNU Compatible. The
following tells it that we do:
cat > config.cache << EOF ac_cv_func_malloc_0_nonnull=yes ac_cv_func_realloc_0_nonnull=yes EOF
Prepare Psmisc for compilation:
./configure --build=${CLFS_HOST} --host=${CLFS_TARGET} \
--prefix=/usr --exec-prefix="" \
--cache-file=config.cacheThe meaning of the configure option:
--exec-prefix=""This ensures that the Psmisc binaries will install into
/bin instead of
/usr/bin. This is the
correct location according to the FHS, because some of the Psmisc
binaries are used by the CLFS-Bootscripts package.
Compile the package:
make
Install the package:
make DESTDIR=${CLFS} installThere 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/binBy 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 -sfv killall ${CLFS}/bin/pidofReports the Process IDs (PIDs) of processes that use the given files or file systems | |
Kills processes by name; it sends a signal to all processes running any of the given commands | |
Reports the Process IDs (PIDs) of processes that use the given files or file systems | |
Displays running processes as a tree | |
Same as pstree, except that it waits for confirmation before exiting |
