Getting 'An internal error occurred during: "Compacting resource model".' when building a project in eclipse indigo

Question

I am getting the following error when building a project in eclipse indigo:

 An internal error occurred during: "Compacting resource model". Java heap.

1. Is this a memory problem?

2. Is it possible to compile a single package in eclipse (like similar to netbeans)? I had got a similar memory problem in netbeans but I got around it by compiling smaller number of packages at a time.

I had compiled the same project in ganemede without any problem.

UPDATE:

Answer 1

Open eclipse configuration(eclipse.ini) file folder from eclipse directory

-vmargs
-Xms128m
-Xmx512m
-XX:MaxPermSize=128m

place this code ...its work for me

Answer 2

You need more heap (RAM).

-Xmx in the eclipse.ini file (for me on Linux Ubuntu it is here: "/home/my_username/eclipse/cpp-2019-12/eclipse/eclipse.ini") specifies the maximum heap space (RAM) you are authorizing Eclipse to use. Give it more. If -Xmx512m (512 MB) of RAM isn't enough, try more: -Xmx1024m, or -Xmx2048m, etc, until it is enough and you quit getting crashes.

I talk about this in my Eclipse document here:

1. readme with links to it in PDF or Google Drive form: https://github.com/ElectricRCAircraftGuy/eRCaGuy_dotfiles/tree/master/eclipse

Eclipse is powerful, but it is a terrible terrible terrible memory hog. On some machines for some repos I set it to -Xmx32768 (32 GB--yeah--nuts--but try letting Eclipse index a massive repo with the Boost library included and this still isn't enough).
