Cross-Compiled Linux From Scratch - Version GIT-20170803-MIPS

Chapter 10. Installing Basic System Software

10.64. D-Bus-1.10.18

D-Bus is a message bus system, a simple way for applications to talk to one another.

10.64.1. Installation of D-Bus

Prepare D-Bus for compilation: 

./configure \
    --prefix=/usr \
    --sysconfdir=/etc \
    --libexecdir=/usr/lib/dbus-1.0 \
    --localstatedir=/var \
    --with-systemdsystemunitdir=/lib/systemd/system \
    --docdir=/usr/share/doc/dbus-1.10.18

Compile the package: 

make

This package does come with a test suite, but it requires several packages that are not included in CLFS. Instructions for running the test suite can be found in the CBLFS wiki at http://cblfs.clfs.org/index.php/D-BUS_Core.

Install the package: 

make install

Move the shared library to /lib and recreate the symbolic link. 

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

Create a symlink so that D-Bus and systemd can use the same machine-id file: 

ln -sv /etc/machine-id /var/lib/dbus
