[antlr-interest] Memory issue with ANTLR

[Jayani Withanawasam]

Thanks Mark,

I could resolve this after increasing the max heap size of the JVM using
the following command:
java -Xmx750M -cp "c:\antlr\antlr-3.1.3.jar" org.antlr.Tool
-Xconversiontimeout 30000 *.g

I have not build the grammer files correctly and that is why I got
reference issues.

Regards,
Jayani.

Hi Jayani,

Right so you still get this error:

IAstRuleReturnScope sounds like it might be something in your
code, or in the C# code that was generated by the antlr tool
from the .g files, or maybe something in the C# antlr runtime.

You could try:

- checking the C# files generated from the antlr tool are linked into
the
  application
- searching for IAstRuleReturnScope in the generated C# files, and in
the .g
  files
- searching for IAstRuleReturnScope in the C# runtime
- searching for IAstRuleReturnScope in the string template files (.stg)
for
  the C# runtime in the antlr tool source code

Actually its in there, maybe that gives some more hints:

% grep IAstRuleReturnScope **/*.stg
tool/src/main/resources/org/antlr/codegen/templates/CSharp2/AST.stg:,
IAstRuleReturnScope\<<ASTLabelType>\>
tool/src/main/resources/org/antlr/codegen/templates/CSharp3/AST.stg:,
IAstRuleReturnScope\<<ASTLabelType>\>
tool/target/classes/org/antlr/codegen/templates/CSharp2/AST.stg:,
IAstRuleReturnScope\<<ASTLabelType>\>
tool/target/classes/org/antlr/codegen/templates/CSharp3/AST.stg:,
IAstRuleReturnScope\<<ASTLabelType>\>
%
