The following article explains how to install Eclipse on your computer. The guide is targeted to students of the Java Programming course available on Art of Problem Solving. The version that we will be using is: Eclipse IDE for Java Developers, version 4.2.
Since the installation is system-specific for Mac, Windows, and Ubuntu, read and follow the instructions for the system that you have installed.
Linux/Ubuntu
Check if your system is 32- or 64-bit. You can accomplish this by opening a Terminal, and typing:
$ uname -m
If you get back: x86_64, then you have a 64-bit system, otherwise, you have 32-bit system.
Go to: Ubuntu Downloads. On the third line from the top, that says: Eclipse IDE for Java Developers, click the Linux 32 Bit or Linux 64 Bit link on the right, depending on the type of your system.
Download the relevant distribution of Eclipse (i.e. the tar.gz source file, which is an archive that conta).
The next step is to extract the tar.gz source file. Open Terminal and navigate to the location where the tar.gz file was saved. Then, run:
tar xzf eclipse-java-juno-linux-gtk.tar.gz
tar xzf eclipse-java-juno-linux-gtk.tar.gz
Next, move the created eclipse executable to the /opt/ system folder. After entering the following command into Terminal, you need to enter the root password.
$sudo mv eclipse /opt/
Now navigate to the /opt/ folder if you are not there already. Change the permissions on the eclipse executable to sudo chown -R root:root eclipse & sudo chmod -R +r eclipse
Create an executable in your path, and open the text editor Nano: sudo touch /usr/bin/eclipse & sudo chmod 755 /usr/bin/eclipse &sudo nano /usr/bin/eclipse
Now enter the following text into Nano:
- !/bin/sh
- export MOZILLA_FIVE_HOME="/usr/lib/mozilla/"
export ECLIPSE_HOME="/opt/eclipse"$ (Error compiling LaTeX. Unknown error_msg)ECLIPSE_HOME/eclipse $*
Save your work (CTRL+o) and close Nano(CTRL+x)
Now run Eclipse for the first time: /opt/eclipse/eclipse -clean &
(every next time you rin Eclipse, just enter eclipse in Terminal).
Note: If you get an error about Java not installed, make you have Java Virtual Machine installed. You can do this by either installing OpenJDK Java 7 Runtime from the Ubuntu Software Center, or running the following command in Terminal: sudo apt-get install openjdk-7-jre
