SJava
Thank you Prof Ripley for your guidance. I re-installed gpp and SJava installed correctly. I am now running into this problem: When I load the SJava library I get:
library(SJava)
Error in dyn.load(x, as.logical(local), as.logical(now)) :
unable to load shared library
"/usr/local/lib/R/site-library/SJava/libs/SJava.so":
libRSNativeJava.so: cannot open shared object file: No such file or directory
Error in library(SJava) : .First.lib failed for 'SJava'
The file does exit:
$ ls -la /usr/local/lib/R/site-library/SJava/libs/SJava.so
-rwxr-xr-x 1 root staff 283388 Nov 18 13:27
/usr/local/lib/R/site-library/SJava/libs/SJava.so
I then ran:
$ R CMD ldd /usr/local/lib/R/site-library/SJava/libs/SJava.so
libRSNativeJava.so => not found
libjvm.so => not found
libR.so => /usr/lib/R/lib/libR.so (0x40014000)

/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
libjvm.so does exist in 4 locations in my intel box running debian:
/opt/splus/java/jre/lib/i386/client/libjvm.so
/opt/splus/java/jre/lib/i386/server/libjvm.so
/opt/j2sdk1.4.2_06/jre/lib/i386/server/libjvm.so
/opt/j2sdk1.4.2_06/jre/lib/i386/client/libjvm.so
I have JAVA_HOME defined as:
$ echo $JAVA_HOME
/opt/j2sdk1.4.2_06/
Your further help is greatly appreciated.

Seem pretty straightforward to me: either gpp is not a C++ compiler or it does not work (possibly because LD_LIBRARY_PATH does not contain its run-time libraries). On Thu, 18 Nov 2004, Yasser El-Zein wrote:
