Linux: 2.4.21-27.0.2.EL #1 Wed Jan 12 23:35:46 EST 2005 i686 athlon i386 GNU/Linux
The version of JDBC driver to be built: 3

What version of the driver are you trying to build?

and equally important, what version of the J2SDK is installed?


    $ java -version
    java version "1.4.2_04"
    ......

    $ which javac
    /usr/java/j2sdk1.4.2_04/bin/javac

Ah, ok.

This is very old code. It predates 1.5 and so it's not too suprising
that it doesn't build under 1.5. I suggest you build from source
available at jdbc.postgresql.org or use a prebuilt jar from the same
location. Don't pass --with-java to avoid trying to build the driver
provided with 7.4.3 (that flag only triggers the driver build -- it does
not change how the server or client utils are built).

I'd also suggest you use the latest 7.4.x server, not 7.4.3. There are
data-loss bugs that have been fixed since 7.4.3.
