Xapian discuss - May 2007 - java bindings 1.0.0 - jni.h not found

Hi all,

I am new to Xapian and want to use it with Java. In order to do that I tried
to compile the Java bindings. I set XAPIAN_CONFIG and invoked
"configure".
However "./configure --with-java" exits with an error.

Point of failure:
  checking for jni.h... no
  checking for jni.h in /usr/lib/jvm/java-1.5.0-sun/include... no
  checking for jni.h in /usr/lib/jvm/java-gcj/include... no
  checking for jni.h in
/System/Library/Frameworks/JavaVM.framework/Headers... no
  configure: error: jni.h not found

Note that I have added JAVA_HOME to my path and if I look into the directory
"/usr/lib/jvm/java-1.5.0-sun/include" there is a "jni.h"
file - This
directory does not appear if I don't set JAVA_HOME.

Next I tried to set the variable JNI_INCLUDE_DIR. No effect at all.

The script claims to look in the proper location, but doesn't find anything.

OS: Ubuntu 7.04
gcc/g++: Ubuntu 4.1.2-0ubuntu4 (gcc/g++ version 4.1.2 as ubuntu package)

Any ideas?


Cheers,

Martin

Erm... JAVA_HOME needs to be added to your *environment*, not your
path...

Hi again,

ok - for clarification:

1. "add JAVA_HOME to my path": yes I added it to my *environment* -
wrong
terminology, my fault

2. java-package: yes, the (ubuntu-packaged) jdk is installed

cu,

Martin

Cool. What does echo $JAVA_HOME say?

$JAVA_HOME says:

"/usr/lib/jvm/java-1.5.0-sun"

 which is a link to  "./java-1.5.0-sun-1.5.0.11"
I tried to set JAVA_HOME to the real directory as well. No change.

As James says, config.log should show why this jni.h isn't being picked
up.  The test just tries to compile:

#include <jni.h>

JNI_INCLUDE_DIR is never actually used!  I'll fix that, but the problem
here seems to be the test for jni.h.

That's what I'm using, so if it's not obvious what's up from
config.log
I can investigate.
