Java version problem in installing yarp for MATLAB in Ubuntu 16.04 #1297

Hi, My ubuntu 16.04 system has java 1.8 version in it. While I try to install the MATLAB bindings by following the instructions from the webpage, the LoadYarp and YarpImageHelper class files are built. But, when I run the LoadYarp command in matlab by adding the paths to the classpath.txt and also librarypath.txt, I get the following error

Java exception occurred: java.lang.UnsatisfiedLinkError: /home/hari/yarp/bindings/build/libjyarp.so: /usr/local/MATLAB/R2017a/bin/glnxa64/../../sys/os/glnxa64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /home/hari/yarp/bindings/build/libjyarp.so) at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary1(Unknown Source) at java.lang.ClassLoader.loadLibrary0(Unknown Source) at java.lang.ClassLoader.loadLibrary(Unknown Source) at java.lang.Runtime.loadLibrary0(Unknown Source) at java.lang.System.loadLibrary(Unknown Source) at LoadYarp.(LoadYarp.java:18)

I could not work around the issue. Most probably, the problem is due to the different java version that the yarp plugins need, but i'm not sure.

Thank you very much.

Hi @Hteja , I don't think this error is Java-specific. See https://github.com/robotology/codyco-superbuild/issues/141 for a similar issue.
