Hi, Shiran,
The problem we are facing seems to be that the libfastbitjni.lo can
not be moved to a directory other than the one specified at configure
time. If a prefix was not specified when running the configure
script, then it is default to /usr/local. I have not been doing a lot
of tests on java side, therefore, have not bothered to figure out a
solution.
If you share with us your build.xml and build.properties, I would be
more than happy to try it out and include them in the next release
provided that I can get them to work. How does that sounds to you?
