Hi,

Thanks for this new report :)

Fixed by revision 928 @ NL4J : 
http://code.google.com/p/nativelibs4java/source/detail?r=928

You can build this revision from sources (please see 
http://code.google.com/p/javacl/wiki/Build) or wait for an update of 
JNAerator's 
snapshot binaries.
I've attached the JNAerated JAR and the corresponding .jnaerator file for your 
convenience.

Cheers

I did the build and tried

java -jar 
~/.m2/repository/com/jnaerator/jnaerator/0.9.4-SNAPSHOT/jnaerator-0.9.4-
SNAPSHOT.jar

Assuming that's right, why do I get:

Exception in thread "main" java.lang.NoClassDefFoundError: 
com/ochafik/lang/jnaerator/parser/Identifier
Caused by: java.lang.ClassNotFoundException:

Could not find the main class: com.ochafik.lang.jnaerator.JNAerator. Program 
will 
exit.

Thanks!

You need to use the -shaded.jar suffixed jar, which contains all Maven 
transitive dependencies.
Cheers
