6.49. Kmod-5

The Kmod package contains libraries and utilities for loading kernel modules

Approximate build time: less than 0.1 SBU
Required disk space: 16.0 MB

6.49.1. Installation of Kmod

Prepare Kmod for compilation:

liblzma_CFLAGS="-I/usr/include" \
liblzma_LIBS="-L/lib -llzma"    \
zlib_CFLAGS="-I/usr/include"    \
zlib_LIBS="-L/lib -lz"          \
./configure --prefix=/usr --bindir=/bin --libdir=/lib --sysconfdir=/etc \
            --with-xz     --with-zlib

The meaning of the configure options:

lib* and --with-*

These options enable Kmod to handle compressed kernel modules. The shell variables are required in order for the xz and zlib headers and libraries to be found in the absence of pkg-config.

Compile the package:


To test the results, issue:

make check

Install the package, and create symlinks for compatibility with Module-Init-Tools, the package that previously handled Linux kernel modules:

make pkgconfigdir=/usr/lib/pkgconfig install
for target in depmod insmod modinfo modprobe rmmod; do
  ln -sv ../bin/kmod /sbin/$target
ln -sv kmod /bin/lsmod

Short Descriptions


Creates a dependency file based on the symbols it finds in the existing set of modules; this dependency file is used by modprobe to automatically load the required modules


Installs a loadable module in the running kernel


Loads and unloads kernel modules


This library is used by other programs to load and unload kernel modules


Lists currently loaded modules


Examines an object file associated with a kernel module and displays any information that it can glean


Uses a dependency file, created by depmod, to automatically load relevant modules


Unloads modules from the running kernel
