The Java section of the Admin Guide currently reads: "Check if a JRE is installed by running java -version in a Terminal window: if Java is not installed this should prompt you to install it.
However, you may want/need to install the latest Java from Oracle (currently Java 7 fromhttp://www.oracle.com/technetwork/java/javase/downloads/index.html); this is for Lion and later." When I upgraded to Yosemite (from Snow Leopard), I installed the Jave SE development kit from: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html I was informed that Java 7 in Yosemite is not supported and that Java 8 is required. From Terminal session I run: $ java -version ### I get: java version "1.8.0_25" Java(TM) SE Runtime Environment (build 1.8.0_25-b17) Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode) ### And when I run: $ /usr/libexec/java_home -V -a x86_64 ### Iget Matching Java Virtual Machines (1): 1.8.0_25, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home /Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home ### I then ran: R CMD javareconf ### and after some compiler messages I eventually see: …omitting several lines Java home path : /Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home/jre …. omitting several more, then... Updating Java configuration in /Library/Frameworks/R.framework/Resources Done. I hope this means I’m "good to go” and that I do not need make further efforts at setting environment variables. - David Winsemius, MD Alameda, CA, USA _______________________________________________ R-SIG-Mac mailing list [email protected] https://stat.ethz.ch/mailman/listinfo/r-sig-mac
