You are right, the MLRClassifier appears to produce a segmentation fault
now, on Debian-based Linux platforms at least. I have reproduced the
problem (see below for the steps I went through).
Looking at the error report generated by Ubuntu, the segmentation fault
seems to be due to an infinite recursion in /lib/libR.so.
So far, the issue seems limited to the MLRClassifier. Other R code executed
through WEKA's RPlugin doesn't appear to cause a problem.
Building an MLR classifier ("rpart") on the iris data in R itself does not
cause any issue either though.
I have tried downgrading to older versions of the mlr package in R, but
that did not help.
Cheers,
Eibe
My set-up
Ubuntu 22.04
WEKA 3.8.6
R 4.3.0
RPlugin 1.2.33
Intel 64-bit
First of all, the default Java installed on my machine wasn't a JDK, just a
JRE, which isn't sufficient to install the RPlugin on Linux. First, I
installed the Zulu OpenJDK 17 (JDK FX version) from
https://www.azul.com/downloads/#downloads-table-zulu using:
$ sudo dpkg -i zulu17.42.19-ca-fx-jdk17.0.7-linux_amd64.deb
Even though this became the default Java on my system after installation,
this was still insufficient when running R to reconfigure the version of
Java to use:
$ sudo R CMD javareconf
Java interpreter : /usr/lib/jvm/default-java/bin/java
Java version : 11.0.19
Java home path : /usr/lib/jvm/default-java
Java compiler : /usr/bin/javac

Done.
The problem was that this command doesn't seem to use the default JVM, but
/usr/lib/jvm/default-java, which still pointed to the Java 11 JRE in my
case. I had to run
sudo apt remove default-jre-headless
to remove the default-java. Following that, there was progress
$ sudo R CMD javareconf

Done.
Unfortunately, installation of the RPlugin in WEKA with the WEKA package
manager still failed after this. Trying to install rJava manually in R
using install.packages("rJava") showed that a couple of system libraries
required by rJava seemed to be missing:
...
/usr/bin/ld: cannot find -llzma: No such file or directory
/usr/bin/ld: cannot find -lbz2: No such file or directory
...
I had to install these using
$ sudo apt-get install libbz2-dev
...
$ sudo apt-get install liblzma-dev
...
Following that, running
$ ./weka.sh -jvm /usr/lib/jvm/zulu-fx-17-amd64/bin/java
in $HOME/weka-3-8-6 worked smoothly initially: WEKA's RPlugin package was
able to automatically install the rJava package in R at start-up. Also,
going to the Classify tab in the WEKA Explorer and attempting to select a
classifier by clicking on the "Choose" button triggered the automatic
installation of the mlr package in R from WEKA. This takes quite a while
(about 5 minutes on my system?) because it is compiled from source on Linux
when it is installed.
Unfortunately, after compilation had finished, WEKA crashed completely with
a segmentation fault.
