问题描述

I have came across this problem while installing rJava on R3.0.1: "configure: error: One or more JNI types differ from the corresponding native type"

The detailed message is attached below. I searched for similar problems but my issue is a little trickier and many proposed solutions either didnt work or I could not try, because I am working on a server which I do not have write access to system libraries.

OS: Linux 2.6.18-348.6.1.el5 #1 SMP Tue May 21 15:44:27 EDT 2013 x86_64 x86_64 x86_64 GNU/Linux (info given by typing "uname -a" sorry I couldn't quite understand this info)

R: R3.0.1, I downloaded the source, put in my home directory, and built R from source.

rJava: I ran 'install.packages("rJava")', during installation I got:

=========================
checking Java support in R... present:
interpreter : '/usr/bin/java'
archiver : '/usr/bin/jar'
compiler : '/usr/bin/javac'
header prep.: '/usr/bin/javah'

rver -ljvm'
checking whether JNI programs can be compiled... yes
checking JNI data types... configure: error: One or more JNI types differ from the
corresponding native type. You may need to use non-standard compiler flags or
a different compiler in order to fix this.
ERROR: configuration failed for package 'rJava'
* removing '/home/me/R-3.0.1/library/rJava'

==================================

Since I can only access the server remotely, I do not have write access to anything outside my home directory /home/me.

Any information would be highly appreciated!

I ran into the same problem trying to install.packages("rJava") in R version 3.0.2, as long as I tried to install as ordinary user (Linux, Debian). There was no problem running install.packages("rJava") as root. Then, trying library(rJava) worked for root but not for me as a user:

Error : .onLoad failed in loadNamespace() for 'rJava', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
  error: unable to load shared object '/usr/usr.local.original.Debian/lib/R/site-library/rJava/libs/rJava.so':
  libjvm.so: cannot open shared object file: No such file or directory

This problem required to add the environment variables JAVA_HOME and LD_LIBRARY_PATH to ~/.login (following instructions found at Trouble in Setting Java Environment Path on Ubuntu (libjvm.so: cannot open shared object file: No such file or directory)):

setenv JAVA_HOME /usr/lib/jvm/java-7-oracle/
setenv LD_LIBRARY_PATH $JAVA_HOME/jre/lib/amd64:$JAVA_HOME/jre/lib/amd64/server

# For c-shell; for bash, it would have to be:
export JAVA_HOME=/usr/lib/jvm/java-7-oracle/
export LD_LIBRARY_PATH=$JAVA_HOME/jre/lib/amd64:$JAVA_HOME/jre/lib/amd64/server

So, you would have to have a system administrator install rJava for you, then set your environment variables and, of course, set your own .libPaths() in R such as to find rJava.
