[R] SJava embedded in R

[Nathan Whitehouse]

Hi,

  Here's some suggestions for troubleshooting the
install.  

  The CLASSPATH needs to be 
$SJAVA_HOME/org/omegahat/Jars/Environment.jar,
$SJAVA_HOME/org/omegahat/Jars/antlr.jar
$SJAVA_HOME/org/omegahat/Jars/jas.jar
$SJAVA_HOME.

This allows the java compiler/interpreter to find
  1)the ROmegahatInterpreter and REvaluator classes(in
a org/omegahat/R/Java tree under SJava
  2)& the base omegahat interpreter libraries from
which the ROmegahatInterpreter & REvaluator classes
descend.(Found in those jar files)

   on Unix-like systems,
  the LD_LIBRARY_PATH has to point to the shared
objects(so)/dynamic linking libraries, usually in 
   
  $R_HOME/libs.

  These .so/.dll files have to be symbolically linked
to other names.  This is because the Java/JNI loader
needs a specific naming convention to load symbol
libraries/shared objects(something to do with platform
compatibility.)

  R INSTALL -c SJava-version.tar.gz
  (-c executes a cleanup script which performs the
linking)

  I would doublecheck to make sure you have R compiled
as a shared library.  Easily- look in R_HOME/bin for
libR.so. (or, I assume libR.dll)

  Hope some of this will help.
  
  happy pinball,

I downloaded it and installed it with all the
recommended options. I
created the LD_LIBRARY_PATH
environment variable but my java compiler (latest
version) can't find
packages like org.omegahat.R.java and cannot resolve
symbol (class) 
like
REvaluator, RForeignReference...  any idea ?

many thanks for answering my last question I promise !
best regards,
Anthony
