[antlr-interest] problems building antlr using antlr.build.Tool

[John Clayton]

Hi Everyone,

I am new to ANTLR, and foolishly making changes ;-)  So, I want to  
build the java version and following the instructions in install.html,  
I build the antlr/build/ dir, no problems there.  Then, from  
antlr-2.7.2 I run through the following:

% java antlr.build.Tool build
Exception in thread "main" java.lang.NoClassDefFoundError:  
antlr/build/Tool

Ok, set the classpath to here:

% java -cp . antlr.build.Tool build
antlr.build.Tool: no such action for application antlr.build.ANTLR
java.lang.reflect.InvocationTargetException

Hmmm, found the Tool now, but seems to have a problem reflecting a  
method in ANTLR because antlr.Tool isn't compiled.  Let's try giving it  
the jar to bootstrap:

% java -cp antlr.jar:. antlr.build.Tool build
executing: java antlr.Tool -o  
/Users/johnclay/Cocoa/Parsers/ANTLR/antlr-2.7.2-objc/antlr  
./antlr/antlr.g
cannot write to  
'/Users/johnclay/Cocoa/Parsers/ANTLR/antlr-2.7.2-objc/antlr/ 
ANTLRParser.java'
executing: java antlr.Tool -o  
/Users/johnclay/Cocoa/Parsers/ANTLR/antlr-2.7.2-objc/antlr  
./antlr/tokdef.g
cannot write to  
'/Users/johnclay/Cocoa/Parsers/ANTLR/antlr-2.7.2-objc/antlr/ 
ANTLRTokdefLexer.java'
executing: java antlr.Tool -o  
/Users/johnclay/Cocoa/Parsers/ANTLR/antlr-2.7.2-objc/antlr/preprocessor  
./antlr/preprocessor/preproc.g
cannot write to  
'/Users/johnclay/Cocoa/Parsers/ANTLR/antlr-2.7.2-objc/antlr/

executing: java antlr.Tool -o  
/Users/johnclay/Cocoa/Parsers/ANTLR/antlr-2.7.2-objc/antlr/actions/java  
./antlr/actions/java/action.g

/Users/johnclay/Cocoa/Parsers/ANTLR/antlr-2.7.2-objc/antlr/actions/ 
csharp ./antlr/actions/csharp/action.g
cannot write to  
'/Users/johnclay/Cocoa/Parsers/ANTLR/antlr-2.7.2-objc/antlr/actions/ 
csharp/ActionLexer.java'
executing: javac -d . ./antlr/*.java
./antlr/ANTLRGrammarParseBehavior.java:10: package  
antlr.collections.impl does not exist
import antlr.collections.impl.BitSet;
                               ^


Ok, so it has permissions problems and some compiler errors.  Let's  
deal with permissions:

% sudo java -cp antlr.jar:. antlr.build.Tool build
executing: java antlr.Tool -o  
/Users/johnclay/Cocoa/Parsers/ANTLR/antlr-2.7.2-objc/antlr  
./antlr/antlr.g
executing: java antlr.Tool -o  
/Users/johnclay/Cocoa/Parsers/ANTLR/antlr-2.7.2-objc/antlr  
./antlr/tokdef.g
./antlr/tokdef.g:175:36: warning:lexical nondeterminism between alts 1  
and 2 of block upon
./antlr/tokdef.g:175:36:     k==1:'0'..'9'
./antlr/tokdef.g:175:36:     k==2:'\u0003'..'\u00ff'
./antlr/tokdef.g:175:44: warning:lexical nondeterminism between alts 1  
and 2 of block upon


... processing lots of g files with lots of nondeterminism errors ...

executing: javac -d . ./antlr/*.java
./antlr/ANTLRGrammarParseBehavior.java:10: package  
antlr.collections.impl does not exist
import antlr.collections.impl.BitSet;
                               ^

... ad infinitum ...


All right, we have fixed everything except that now as soon as the  
build tool starts compiling it wigs out and can't find anything.  I  
tried sending in:
-Dantlr.build.root=/Users/me/antlr-2.7.2 (on OS X) but got:
antlr.build.Tool: Property antlr.build.root==/Users/me/antlr-2.7.2 does  
not exist

Can anyone point me in the right direction?  Thanks a whole big bunch.   
I'll keep horsing with the classpath.


Regards,

John Clayton
