Installation of xterm

Install xterm by running the following commands: 

sed -i '/v0/{n;s/new:/new:kb=^?:/}' termcap &&
printf '\tkbs=\\177,\n' >> terminfo &&

TERMINFO=/usr/share/terminfo \
./configure $XORG_CONFIG     \
    --with-app-defaults=/etc/X11/app-defaults &&

make

This package does not come with a test suite.

Now, as the root user: 

make install &&

mkdir -pv /usr/share/applications &&
cp -v *.desktop /usr/share/applications/

Command Explanations

sed -i ... termcap, printf ... >> terminfo: These commands modify the terminal description so that the Backspace key is expected to send the character with ASCII code 127. This is done for consistency with the Linux console.

TERMINFO=/usr/share/terminfo: This ensures that the xterm terminfo files are installed to the system terminfo database.

--with-app-defaults=...: Sets the location for the app-defaults directory.

Configuring xterm

There are two ways to configure xterm. You can add the X resource definitions to the user's ~/.Xresources file, or add them to the system-wide $XORG_PREFIX/share/X11/app-defaults/Xterm file.

In order for xterm to follow the locale settings in the environment, use TrueType fonts, and follow the Linux convention about the code sent by the Backspace key, add the following definitions as the root user: 

cat >> /etc/X11/app-defaults/XTerm << "EOF"
*VT100*locale: true
*VT100*faceName: Monospace
*VT100*faceSize: 10
*backarrowKeyIsErase: true
*ptyInitialErase: true
EOF
