Installing xonclock

xonclock is an analog clock for linux desktop. I just installed it on my Ubuntu. There were a few issues when trying to install.

Issue 1: Issue with ./configure

Solved by firing up the terminal and typing
sudo ln -s /usr/include/freetype2/freetype /usr/include/freetype

Issue 2: Issue with placement.o

Error was similar to
/usr/bin/ld: placement.o: undefined reference to symbol 'sincosf@@GLIBC_2.2.5'
/usr/bin/ld: note: 'sincosf@@GLIBC_2.2.5' is defined in DSO /usr/lib/

Solved by running
./configure LIBS=-lm

then doing make
Issue 3: Unable to parse .xonclockrc

After this, for some reason the config file for xonclock was missing. So I copied the xonclockrc-example from src folder to .xonclockrc in the home directory by

cp src/xonclockrc-example ~/.xonclockrc

Issue 4: Start automatically on login

On ubuntu, open Startup Application, click on Add and put the name and xonclock in the command.
