Apologies if this has been covered elsewhere, but I couldn’t find anything authoritative.

I thought I’d confirm for those wondering about installing on 64-bit systems that I’ve had no problems installing and running MyEclipse 6.0M1 GA with Eclipse 3.3 64-bit on Sun Java 1.6 64-bit, on Ubuntu Gutsy (tribe-5) 64-bit.

I took the precaution of renaming the existing Eclipse (32-bit) user settings directory before I started to prevent any type-size mishaps.

I also customised the location of Eclipse 3.3 so it could co-exist with previous installations until I was sure it was stable (I run 32-bit and 64-bit installations with the same /home mount).

Here’s the sequence of shell commands that captures the steps I took including configuration changes for performance. They could be inserted into a bash script and run that way rather than cut/paste to a terminal:

# protect any existing 32-bit configuration
mv  ~/.eclipse ~/.eclipse-32bit

# install the JDK, which depends on sun-java6-jre and sun-java6-bin
sudo apt-get install sun-java6-jdk

# ensure Sun Java6 is the default java
update-alternatives --config java

# download Eclipse 3.3 64-bit for Linux
wget http://www.mirrorservice.org/sites/download.eclipse.org/eclipseMirror/eclipse/downloads/drops/R-3.3-200706251500/eclipse-SDK-3.3-linux-gtk-x86_64.tar.gz

# fetch the standard Ubuntu Eclipse 3.2.x 64-bit starter script and docs
wget http://archive.ubuntu.com/ubuntu/pool/universe/e/eclipse/eclipse_3.2.2-0ubuntu3_amd64.deb

# all we want is /usr/bin/eclipse
mkdir /tmp/eclipse;
dpkg -x eclipse_3.2.2-0ubuntu3_amd64.deb /tmp/eclipse

# fix-up the launcher script with our '3.3' specific values
sed -i -e 's:/usr/lib/eclipse/startup.jar::' \
   -e 's:/usr/lib/eclipse:/usr/lib/eclipse-3.3:' \
   -e 's:/usr/local/lib/eclipse:/usr/local/lib/eclipse-3.3:'  \
 /tmp/eclipse/usr/bin/eclipse

# rename, make it executable, and move it into place
mv /tmp/usr/bin/eclipse /tmp/usr/bin/eclipse-3.3
sudo cp /tmp/usr/bin/eclipse-3.3 /usr/bin/
sudo chmod g+x /usr/bin/eclipse-3.3
sudo chown root:root /usr/bin/eclipse-3.3
# from now on eclipse 3.3 can be launched using then command "eclipse-3.3"

# copy the icons too
sudo cp /tmp/eclipse/usr/share/pixmaps/* /usr/share/pixmaps/

# create a separate directory for 3.3, to protect existing versions
sudo mkdir /usr/lib/eclipse-3.3
sudo tar -xzf eclipse-SDK-3.3-linux-gtk-x86_64.tar.gz -C /usr/lib/eclipse-3.3

# create an extension location for installing Eclipse 3.3 features for all users
sudo mkdir /usr/local/lib/eclipse-3.3

# allow all users to install to the location
# this allows additional features to be installed without su privileges
sudo chown root:staff /usr/local/lib/eclipse-3.3
sudo chmod a+xw /usr/local/lib/eclipse-3.3
if [ "x$(egrep "staff:.*:${USER}" /etc/group)" = "x" ]; then  \
  sudo usermod -aG staff ${USER}; \
  echo "Added to group 'staff'. You will need to logout before this change will take effect"; \
  fi

# download the MyEclipseIDE manual install archive 
wget http://downloads.myeclipseide.com/downloads/products/eworkbench/6.0GA/MyEclipse_6.0GA_E3.3_ManualInstall.zip 

# create a directory for MyEcliseIDE and install
sudo mkdir /usr/lib/myeclipse
sudo unzip MyEclipse_6.0GA_E3.3_ManualInstall.zip -d /usr/lib/myeclipse

# configure Eclipse for higher memory usage

# configure Linux for more user file handles (Eclipse features can demand more than the default 1024)
sudo sh -c "echo  \"${USER} \t\thard \tnofile \t\t32768\" >> /etc/security/limits.conf"

# now start Eclipse
# watch for and deal with any error reports
eclipse-3.3

# The first thing to do is install all additional optional features such as the CDT (C/C++ tools)
# When asked where to install them, choose '/usr/local/lib/eclipse-3.3' so that platform features
# are available to everyone
# ** REMEMBER ** to do this you'll have needed to log-out/log-in to ensure you're a member of the 'staff' group

# Now add MyEclipseIDE from Help > Software Updates > Manage Configuration
# right-click "Eclipse SDK" and choose Add > Extension location...
# and navigate to '/usr/lib/myeclipse/eclipse'

# restart and update features as needed

# Now add any menu short-cuts to the display manager menus (Gnome, KDE, etc)
# command is /usr/bin/eclipse-3.3
# icons are in /usr/share/pixmaps/

Thanks for this post. Im sure it would be very helpful for a lot of Linux users here.
