Обсуждение: JDBC interface

I'm working on SuSE 7.1 and I have a problem when I try to make the JDBC 
INterface.
I have jdk1.1.8 and it is in the Path (JAVA_HOME)

When I write make in the directory 
/usr/src/postgresql-7.1.2/src/interfaces/jdbc/ and I get next message:

builfile ../../../build.xml -Dmajor=7-Dminor=1-Dfullversion=7.1.2 
-def_pgport5432


Then, I had installed de package 'ant' (version1.3) and I have 'ant' in the 
Path (ANT_HOME)

When I write 'ant' in the directory 
/usr/src/postgresql-7.1.2/src/interfaces/jdbc/  I get the 6 error  messages 
referers to the file: /src/interfaces/jdbc/org/postgresql/Drivers.java.



What could be happening?
Thank you very much.
