I ran into the same problems some time ago. Apart from the compiler and
Java version to be installed, are you using CDT within Eclipse?
And do you have C/C++ Indexing set to Full?, Then the Indexer lets you run
out of memory. You can change the VM arguments in
Window-Preferences->Java-Installed JREs. Select JRE, edit.
My VM args are as follows:
-vmargs -Xms512m -Xmx512m -XX:PermSize=128m -XX:MaxPermSize=128m

These settings work for me with 1GB of RAM.

I hope this is useful for someone.
