Subject: [Rd] R CMD config doesn't export JAVA_LD_LIBRARY_PATH (PR#13165)
Message-ID: <20081014220003.960C7282EFC1@mail.pubhealth.ku.dk>

R CMD config exports the following variables:

   JAR           Java archive tool command
   JAVA          Java interpreter command
   JAVAC         Java compiler command
   JAVAH         Java header and stub generator command
   JAVA_HOME     path to the home of Java distribution
   JAVA_LIBS     flags needed for linking against Java libraries
   JAVA_CPPFLAGS C preprocessor flags needed for compiling JNI programs

JAVA_LD_LIBRARY_PATH is defined in Makeconf, but not exported. 
Specifically, src/scripts/config includes the following line:
ok_java_vars="JAVA JAVAC JAVAH JAR JAVA_HOME JAVA_LIBS JAVA_CPPFLAGS"

This list does not include JAVA_LD_LIBRARY_PATH, with no explanation of 
why not. Providing this env variable would allow developers to use RPATH 
instead of setting the LD_LIBRARY_PATH variable by hand before running R 
extensions that use Java.
