C++ target throws error with simple grammar T.g
antlr, c++
Solution
The C++ target does not support AST creation (yet).

Problem
I'm trying to target Cpp with a simple grammar T.g outputting to an AST with a tree grammar. Can't find AST.stg, which doesn't exist in the source code. Same error with both 3.4 and 3.5 rc1. Thanks for any help. ``` java -jar ../../../antlr-3.5-rc-1-complete.jar T.g TWalker.g error(10): internal error: T.g : java.lang.IllegalArgumentException: No such group file: org/antlr/codegen/templates/Cpp/AST.stg org.stringtemplate.v4.STGroupFile.<init>(STGroupFile.java:69) org.stringtemplate.v4.STGroupFile.<init>(STGroupFile.java:48) org.antlr.codegen.CodeGenerator.loadTemplates(CodeGenerator.java:222) org.antlr.codegen.CodeGenerator.genRecognizer(CodeGenerator.java:283) org.antlr.Tool.generateRecognizer(Tool.java:661) org.antlr.Tool.process(Tool.java:474) org.antlr.Tool.main(Tool.java:98) ```
