Precompiled binaries... now that's a beautiful thing. With the knowledge that the jars are available pre-built, I was content to proceed with the installation without building the jdbc driver. I've now managed to get the basics up and running (ie, start merovingian, create demo database, start demo database, login using mclient). I was not immediately able to get a graphical client working, but that's a challenge for another day I think... I should have more time to play around with this over the weekend.
Thanks so much to everyone who helped me get going.

Hi Scott,
I guess, Jennie was not refering to JDK 1.5 vs. JRE 1.6, but java 1.5 (reported by ant) vs. javac 1.5.0_16 (reported by configure).
Apart from that, running JDK 1.5 created jar's using JRE 1.6 should be possible --- I recall that I ran the Sun JDK 1.5 created jar's of our release using IcedTea 1.7 on my Fedora 9 Laptop ...
In fact, in case building the MonetDB JDBC driver keep (unexpectedly) failing for you, you might consider simply using the released jar file as downloadable from http://monetdb.cwi.nl/Download/ or http://monetdb.cwi.nl/testing/projects/monetdb/Stable/.DailyBuilds./Release/...

My current thinking is that my installation of ant requires the 1.6 JRE to function. For some reason I've always been changing the default JRE and default javac in tandem: I've never tried a 1.6 JRE and a 1.5 javac (just didn't occur to me until now). I'll give that a try later today and see if it works. Is there a dependency on the default JRE at build time? Once I get it built it should be fine to run .jars built for 1.5 on the 1.6 JRE, right?

Would it be that your ant is using a slightly older version of java, than javac? Because this is the typical situation in which you get the error "Bad version number in .class file".
ant.core.lib: /usr/share/ant/lib/ant.jar ant.home: /usr/share/ant

It looks like was using java 1.5 in both ant and javac, but the last line is definitely concerning. I installed Sun Java 1.6 and I got a much more reasonable ant -diagnostics printout. Of course I need either java 1.4 or 1.5 to build MonetDB... which leaves me in a bit of a bind I guess. For the time being I'll try building Monet with java 1.6 anyway and see how that goes.
If you want to use JDBC, you have to use java 1.4 or 1.5, the 'java' module will not compile with Java 1.6 See for example the configure output: checking for Java >= 1.4, but < 1.6... yes -> 1.5.0_16 found
The JDBC 1.6 API is not compatable with JDBC 1.5 API, and the implementation was no trivial task. Actually, Fabian (our JDBC guy) has tried to implement 1.6, but didn't succeed / hasn't finished due to quite several difficulties. Maybe he can tell you more about this.
Regards,
Jennie

This looks like you have multiple versions of java/javac installed on your system. 'ant' might be using a different java compiler than the one 'javac' in your path (but I unfortunately don't know how to find which javac ant is using...).
`ant -diagnostics` ?
Stefan
Can you maybe search for all java versions you have, and remove/disable all but one version?
Kind regards,
Jennie
