GPM-1.20.7

Introduction to GPM

The GPM (General Purpose Mouse daemon) package contains a mouse server for the console and xterm. It not only provides cut and paste support generally, but its library component is used by various software such as Links to provide mouse support to the application. It is useful on desktops, especially if following (Beyond) Linux From Scratch instructions; it's often much easier (and less error prone) to cut and paste between two console windows than to type everything by hand!

This package is known to build and work properly using an LFS-7.5 platform.

Installation of GPM

Install GPM by running the following commands:

./autogen.sh                                &&
./configure --prefix=/usr --sysconfdir=/etc &&
make

This package does not come with a test suite.

Now, as the root user:

make install                                          &&

install-info --dir-file=/usr/share/info/dir           \
             /usr/share/info/gpm.info                 &&

ln -sfv libgpm.so.2.1.0 /usr/lib/libgpm.so            &&
install -v -m644 conf/gpm-root.conf /etc              &&

install -v -m755 -d /usr/share/doc/gpm-1.20.7/support &&
install -v -m644    doc/support/*                     \
                    /usr/share/doc/gpm-1.20.7/support &&
install -v -m644    doc/{FAQ,HACK_GPM,README*}        \
                    /usr/share/doc/gpm-1.20.7

Command Explanations

./autogen.sh: This command creates the missing configure script.

install-info ...: This package installs an .info file, but does not update the system dir file. This command makes the update.

ln -v -sfn libgpm.so.2.1.0 /usr/lib/libgpm.so: This command is used to create (or update) the .so symlink to the library.

Configuring GPM

Systemd Units

To start the gpm daemon at boot, install the systemd unit from the blfs-systemd-units-20140801 package by running the following command as the root user:

make install-gpm

Config Files
