I am contiually getting errors from eclipse about running out of space on
the java heap while I am examaning C++ code. The little memory gadet at the
bottom of the sceen displays a maximum of 254 megs, I believe for the java
heap. How can I allocate more memory for eclipse to use? Keep in mind I am
very un-unix savvy and this whole environment is new to me. I googled java
heap and it talks about an -Xmm and -Xmx option, but I imagine those are
arguments that need to be passed when eclipse is loaded somehow?

Thanks

The -X?? options are arguments that need to be passed on the Eclipse
command line. They need to follow the -vmargs command line option.
Here is an example:
eclipse -vm path/to/java.exe -vmargs -Xmx512m

This will give Eclipse a max heap size of 512meg. You can adjust the
512 number to find what works for you. Make sure you don't put a space
between the -Xmx and the number.

In your eclipse installation there is an eclipse.ini - depending on your version
there might already be some lines prepared.

You can check your settings
Via Help->About Eclipse->Configuration Details

P.S.: I don't find such a memory gadget (but miss it!)

You can adjust these values also in the file eclipse.ini .
