Hi,
I'm using R.app on Mac OS Lion and when I attempt to build the
rJava package from source I get the following error:
Checking whether JNI programs can be compiled... configure: error:
Cannot compile a simple JNI program. See *config.log* for details.
Make sure you have Java Development Kit installed and correctly
registered in R.
If in doubt, re-run "R CMD javareconf" as root.
ERROR: configuration failed for package 'rJava'
* removing
'/Library/Frameworks/R.framework/Versions/2.14/Resources/library/rJava'
On a fresh Mac OS install, executing the command: sudo R CMD javareconf
fails with:
"No Java runtime present, requesting install. Java interpreter doesn't
work properly." and then initiates fetching of Apple's Java runtime.
executing the command, once the Java runtime is finished completes with
the following output
Java interpreter : /usr/bin/java
Java version : 1.6.0_26
Java home path :
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
Java compiler : /usr/bin/javac
Java headers gen.: /usr/bin/javah
Java archive tool: /usr/bin/jar
*Java library path:*
JNI linker flags : -framework JavaVM
JNI cpp flags : -I$(JAVA_HOME)/include
Updating Java configuration in /Library/Frameworks/R.framework/Resources
Done.
Attempting to build the rJava package again results in the same error as
before.
This causes me to ask a few questions:
1) Is the Java package that my Mac automatically downloaded from Apple
the right package? If not which one should I use?
2) Above there is no Java Library path listed, is this part of my problem?
3) Where is the config.log that R.app generates? Dredging around the
Console.app and the likely places did not reveal it.
For what it is worth I have tried 3 different version of R at this
point: (R-2.13-branch,
<http://r.research.att.com/R-2.13-branch-leopard.pkg>R-2.13-patched for
Lion, R-devel)
Thanks for any help!
