You should add the path where the libjvm.so file is located to the path where ld is searching into. To achieve that, you can add a zoo-project.conf file in the following directory: /etc/ld.so.conf.d/ . Then run ldconfig and ldd again on your zoo_loader.cgi file and it should return the proper location.<br>> > > <br>> > > I hope this helps you to solve the issue.<br>> > > <br>> > > Best regards, <br>> > > <br>> > > > Le 27 avr. 2016 à 16:01, rakesh prithiviraj <rakeshuk@outlook.com> a écrit :<br>> > > > <br>> > > > Hi,<br>> > > > <br>> > > > I am trying to build zoo-kernel with Java support on 64 bit Ubuntu machine.<br>> > > > <br>> > > > /configure --with-js --with-python --with-java=/usr/lib/jvm/java-7-openjdk-amd64/<br>> > > > <br>> > > > "http://www.zoo-project.org/docs/install/installation.html#java-support-optional" assumes that the include/linux and jre/lib/i386/client/ subdirectories exist in /usr/lib/jvm/java-7-openjdk-amd64/, and that the include/linux directory contains the jni.h headers file and that the jre/lib/i386/client/ directory contains the libjvm.so file. <br>> > > > <br>> > > > As I am using OpenJDK (and not Oracle Java), <br>> > > > 1.
