Linux From Scratch - Version 7.5-systemd-rc1

Chapter 6. Installing Basic System Software

6.63. Libdbus-1.8.0

Libdbus package provides a library to communicate with D-Bus messagebus daemon. It is only installed to satisfy circular dependency between Systemd and D-Bus.

Approximate build time: less than 0.4 SBU
Required disk space: 35 MB

6.63.1. Installation of Libdbus

[Note]

Note

Libdbus is part of the D-Bus sources. You should first unpack the D-Bus tarball and change to the dbus-1.8.0 directory.

Prepare Libdbus for compilation: 

./configure --prefix=/usr \
            --sysconfdir=/etc \
            --localstatedir=/var \
            --libexecdir=/usr/lib/dbus-1.0 \
            --disable-static

Compile the package: 

make -C dbus libdbus-1.la

This package does come with a testsuite, but it is not possible to run it because only part of the package was built.

Install the package: 

make -C dbus lib_LTLIBRARIES=libdbus-1.la \
     install-libLTLIBRARIES \
     install-dbusincludeHEADERS \
     install-nodist_dbusarchincludeHEADERS
make install-pkgconfigDATA

The shared library needs to be moved to /lib, and as a result the .so file in /usr/lib will need to be recreated: 

mv -v /usr/lib/libdbus-1.so.* /lib
ln -sfv ../../lib/$(readlink /usr/lib/libdbus-1.so) /usr/lib/libdbus-1.so
