Hi,
The INSTALL doc states that the FastBit JNI library must be installed in
"/usr/local/lib." I think that's based on the assumption that the Java
installation uses that path as the default value for the system property
"java.library.path." The path is actually different on a different
architecture, such as Mac OS X, that has the "java.library.path" property set
to other paths. This is made slightly more complicated by the fact that under
Ant properties are immutable and that property is set when the VM is launched.
To get around it, I made a few modifications to the build.xml file. First, it
reads properties from a build.properties file (a standard Ant practice):
<property file="build.properties" />
The build.properties can be generated at compile-time. The file contains an
arbitrarily-named argument, say:
fastbit.library.path=${HOME}/lib # Or ${PREFIX}/lib from configure
Then, the following argument is set at the forked process (e.g., java, junit):
<jvmarg value="-Djava.library.path=${fastbit.library.path}"/>
Running the unit tests (target: test) succeeds.
Is this a viable solution for the JNI path problem or are there other reasons
for installing the fastbitjni libraries in /usr/local/lib?
Cheers,
Shiran
