Knut Anders Hatlen updated DERBY-5125:
--------------------------------------
Attachment: javacc5.diff
Hi Zied,
Thanks for doing this work. Packaging up Derby for inclusion in Debian sounds
like a good way to make it more easily available for many users.
I downloaded JavaCC 5 and got Derby to build with it. Note that it's completely
untested for now, but at least it compiles.
There are two issues with JavaCC 5:
- The default JDK level changed from 1.4 to 1.5 so that the generated parser
uses generics. Since Derby compiles most of the code with source/target level
1.4 to make the binaries compatible with older JVMs, it fails to compile code
that uses generics. JavaCC has a flag to change the JDK level back to 1.4.
- The generated file Token.java changed. Derby has made some modifications to
Token.java and checked it into the repository, and now it needs to be
regenerated and updated with the Derby-specific changes. Good news is that
JavaCC has introduced a new option to allow specifying a parent class for the
generated Token class, so now we can customize it without actually having
Token.java checked into the repository.
So, here's what I did to get it to compile with JavaCC 5:
1) Replaced tools/java/javacc.jar with JavaCC version 5
2) Deleted the file java/engine/org/apache/derby/impl/sql/compile/Token.java
3) Applied the attached patch (javacc5.diff)
4) ant clobber && ant all

> I try to and Apache derby into Debian, so I begin to compile derby
> sources [1], derby sources provide each own libs and javacc is one of
> them. In Debian, javacc version is 5.0 [2].
> After some tries, I'm in a this situation : compilation success with the
> official [3] javacc 4.0 and fail with the 5.0 official one.
> I think that is related with javacc options passed in .jj files
> (ex. java/engine/org/apache/derby/impl/sql/compile/sqlgrammar.jj lines 2-14)
> I don't know much about javacc, so I can't resolve unless modifying
> options blindly and I'm afraid that isn't enough ...
> Best regards,
> Zied
