ldconfig rJava does not work

I am working on an open source R package which requires rJava and RWeka and somehow the rJava and RWeka breaks mysteriously on my local machine.

  1. Anyone knows why the rJava could break ?

  2. It seems that the system could not find the shared object, so I did the follwing both:

    sudo ldconfig -l /home/sunxd/R/x86_64-pc-linux-gnu-library/3.3/rJava/libs/rJava.so

besides, I add /home/sunxd/R/x86_64-pc-linux-gnu-library/3.3/rJava/libs/rJava.so into /etc/ld.so.conf and run sudo ldconfig

then I run ldconfig -p | grep rJava, there is no return at all. Anyone knows why? Is it because rJava.so is broken so it did not appear in the cache? If so, how can I check is a .so file is broken ?

Solution

  • Add /home/sunxd/R/x86_64-pc-linux-gnu-library/3.3/rJava/libs to /etc/ld.so.conf, then run sudo ldconfig, then reboot your system.
