Hello Scott,

First of all, thanks for trying MonetDB.

I've been attempting to install MonetDB by compiling the Aug. 2008 superball. My system is 64-bit linux, specifically the Ubuntu Intrepid Ibex alpha . It appears that the installation is failing while compiling the JDBC driver, with the error message:

BUILD FAILED java.lang.UnsupportedClassVersionError: Bad version number in .class file

I'm using the Sun Java 1.5.0 JRE and JDK. You can look at my full installation log here: http://docs.google.com/Doc?id=dhqbmd8x_6fqdnn7c3 Can somebody help me out? I'm hoping I've just made an easily corrected newbie mistake, but I'm out of things to try.

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

Thanks,

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

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/...

In a last minute flash of inspiration, I realized what I was doing wrong with SQuirrel, and thus can confirm that the pre-built JDBC jar's are working for me. So I think I can call this installation a success! Thanks again everybody. On Wed, Sep 24, 2008 at 9:56 PM, Scott Stephens wrote:

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.
