XDCOUTOFMEMORYERROR

Introduction

This page gives information for users attempting to packages with XDC and getting java out of memory error.

Overview

When compiling a XDC package which internally allocates huge amount of memory. For example see below,

Module.xdc:
TableEntry   table[];
Module.xs:
obj.table.length  = 1000; /* Allocates memory from JVM */

Here memory is allocated when length member of this array is assigned some value. If this value is large, it throws java.lang.OutOfMemory error.

Solution

1. Go to controlpanel and click on Java icon

2. Click on Java tab

3. Click on first view button

4. Add -Xms256m or -Xms512m or -Xms1024m to the Java Runtime Parameters field

5. For JRE which comes with XDC packages, click on Find button

6. Click next button

7. Locate XDC JRE directory

8. Click finish button

Now you can perform step4 to increase memory for this JRE distribution.
