Обсуждение: jdbc driver compilation under linux

Hello,

I'm trying to compile JDBC interface for PostgreSQL 6.3 using JDK 1.1.6
under Linux 2.0.34.
I took JDBC sources from PostgreSQL 6.3 distribution.
I also tried with earlier versions of JDK. The problem is that jar
produces 'segmentation fault'.

Here's the whole compilation dump:

javac postgresql/CallableStatement.java
javac postgresql/geometric/PGbox.java
javac postgresql/geometric/PGcircle.java
javac postgresql/geometric/PGlseg.java
javac postgresql/geometric/PGpath.java
javac postgresql/geometric/PGpolygon.java
jar -c0f postgresql.jar $(find postgresql -name "*.class" -print)
SIGSEGV   11*  segmentation violation

I also tried to compile it on earlier version of JDK (1.1.3) with no
results.

Can you help me with solving this problem? I'd like to start practising
java&jdbc programming, but it's hard to do it without driver installed.

Thanks in advance.

jar is broken on some JDK distributions (one of the 1.2 betas is broken
big time). Check to see if there is either:

  * An older version of the JDK affecting this one - usually caused by old
    shared libraries being used before new ones

  * If a more recent version of 1.1.6 is available

I've just tested jar here (Linux JDK 1.1.6v? {not sure what version}) and
it didn't SIGSEGV.

Hmmm, something is broken there. Until recently I've been using 1.1.3v2
for postgresql work since the 6.2 days.

Don't forget to look at the examples... you'd be surprised at what you can
learn from other peoples code.
