如何使用OracleJava1.7使rJava 0.9-3在OSX10.7.4上工作？

Question

有没有人在OracleJava1.7中成功地让rJava 0.9-3在OSX10.7.4上工作呢？

R version 2.15.2 (2012-10-26) -- "Trick or Treat" Platform
x86_64-apple-darwin9.8.0/x86_64 (64-bit)

java version "1.7.0_09"
Java(TM) SE Runtime Environment (build 1.7.0_09-b05)
Java HotSpot(TM) 64-Bit Server VM (build 23.5-b02, mixed mode)

我使用rJava函数和命令行安装了R2.15.2，安装了install.packages。我没有任何错误。

$ R CMD INSTALL rJava
* installing to library ‘/Library/Frameworks/R.framework/Versions/2.15/Resources/library’
* installing *binary* package ‘rJava’ ...

* DONE (rJava)
$ 

如果我使用将1.7放在列表的第一位，但保留1.6 " on "，rJava总是从1.6开始。

如果我使用将1.7放在首位并关闭1.6，rJava会这样做：

> library(rJava)
> .jinit()
JavaVM: requested Java version ((null)) not available. Using Java at "" instead.
JavaVM: Failed to load JVM: /bundle/Libraries/libserver.dylib
JavaVM FATAL: Failed to load the jvm library.
Error in .jinit() : JNI_GetCreatedJavaVMs returned -1
> 

但是，使用系统功能，R本身就可以找到Java1.7。

> system("java -version")
java version "1.7.0_09"
Java(TM) SE Runtime Environment (build 1.7.0_09-b05)
Java HotSpot(TM) 64-Bit Server VM (build 23.5-b02, mixed mode)
> 

1.7需要在/System/Library/Java/JavaConfig.plist中进行特殊输入吗？

版本目录是否需要对1.7进行调整？奇怪的是，电流流向A，A值为1.7，而CurrentJDK映射为1.6

$cd /System/Library/Frameworks/JavaVM.framework/Versions/
$ls -la

lrwxr-xr-x   1 root  wheel   59 Sep 26 10:09 CurrentJDK -> /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents

即使在rJava运行时，路径直接指向1.7个文件或指向/usr/bin/java路径，rJava仍然无法找到或启动Java1.7。

1.7需要JAVA_LD_LIBRARY_PATH变量集吗？

Makeconf:JAVA = /usr/bin/java
Makeconf:JAVAC = /usr/bin/javac
Makeconf:JAVAH = /usr/bin/javah
Makeconf:JAVA_HOME = /Library/Java/JavaVirtualMachines/jdk1.7.0_09.jdk/Contents/Home/jre
Makeconf:JAVA_LD_LIBRARY_PATH = 
Makeconf:JAVA_LIBS = -framework JavaVM
Makeconf:JAVA_CPPFLAGS = -I$(JAVA_HOME)/include

Makeconf:JAR = /Library/Java/JavaVirtualMachines/jdk1.7.0_09.jdk/Contents/Home/bin/jar
Makeconf:JAVA = /Library/Java/JavaVirtualMachines/jdk1.7.0_09.jdk/Contents/Home/jre/bin/java
Makeconf:JAVAC = /Library/Java/JavaVirtualMachines/jdk1.7.0_09.jdk/Contents/Home/bin/javac

Makeconf:JAVA_LD_LIBRARY_PATH =

Makeconf:JAVA_CPPFLAGS = -I$(JAVA_HOME)/include

谢谢你的帮助

我在统计-rosuda发展列表上问了这个问题，并收到了西蒙厄班克的回复。我不认为Windows和Linux在需要从源代码编译Java1.7时有相同的问题，因为我们在Windows和Linux上运行这个程序，并且不需要编译rJava。一旦我有机会尝试，我会向你汇报：

您使用的是针对system编译的二进制文件(在您的系统上是1.6)，所以如果删除Java1.6，就会破坏它。如果要使用Java1.7，则必须重新配置RforJava1.7并重新编译rJava以使用这些设置。请注意，Oracle的(/Library/Java/JavaVirtualMachines/jdk1.7.0_09.jdk)与system (/System/Library/Frameworks/JavaVM.framework)，的位置完全不同，因此它是不可互换的。 此外，Oracle Java 1.7不是一个框架，它是一个很大的混乱，并不是真正为OS设计的，所以您必须手动将它设置为Linux上的设置--这是相当痛苦的。而且它需要重写..。所以如果你真的想进兔子洞，这就是对我有用的东西： JAVA_LD_LIBRARY_PATH=/Library/Java/JavaVirtualMachines/jdk1.7.0_09.jdk/Contents/Home/jre/lib/server JAVA_LIBS='-L/Library/Java/JavaVirtualMachines/jdk1.7.0_09.jdk/Contents/Home/jre/lib/server -ljvm‘JAVA_CPPFLAGS='-I/Library/Java/JavaVirtualMachines/jdk1.7.0_09.jdk/Contents/Home/include -I/Library/Java/JavaVirtualMachines/jdk1.7.0_09.jdk/Contents/Home/include/darwin’R64 R64 javareconf 然后从源安装rJava (R64 -> install.packages("rJava"，type=‘source“))。请注意，它只适用于64位，所以它只适用于64位R。

这对我来说很管用：

情况是我的Java目录配置不正确。

1)第一次运行：sudo R CMD javareconf。它应采取以下措施：

Java interpreter : /usr/bin/java
Java version     : 1.7.0_40
Java home path   : /Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home/jre

Java headers gen.: /usr/bin/javah
Java archive tool: /usr/bin/jar
Non-system Java on OS X

JNI linker flags : -L$(JAVA_HOME)/lib/server -ljvm
Updating Java configuration in /Library/Frameworks/R.framework/Resources
Done.

2)在R中，run：install.packages("rJava",type='source')。安装应该返回完成(RJava)。注意，我必须设置

JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home

当我需要以root用户的身份启动R时: sudo .要作为普通用户运行，请使用

JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home/jre

对我来说，我没有将上面/usr/bin/ Java *的符号链接设置为Java1.7中相应的链接(相反，指向1.6版本)，并因此而感到沮丧。链接应该如下所示：(在R中只需要java、javac、javah和jar )。

$ ls -l /usr/bin/ja*

终于有什么办法了！

Simon :请您将这些说明放在rJava网站/ cran安装说明上.？这是我第一次进这个兔子洞，我肯定我不是唯一一个。
