在Ubuntu 12.04中,我安装了sun/oracle的jdk7.何时locate jni.h,它会打印多个位置

/usr/lib/jvm/java-6-openjdk-amd64/include/jni.h
/usr/lib/jvm/jdk1.7.0_07/include/jni.h
...

在JDK生成的头文件中,有include <jni.h>,并且目前它抱怨

fatal error: jni.h: No such file or directory.

在我看来Makefile,没有关于位置的规范jni.h.我问是否有可能配置某些系统参数以使jni.h(例如/usr/lib/jvm/jdk1.7.0_07/include/jni.h)在编译时知道路径.

嗨,我有来自cran的rJava包的问题.

我安装了

sudo apt-get install openjdk-7-jdk
sudo apt-get install r-cran-rjava

跑了

sudo R CMD javareconf
# Java interpreter : /usr/bin/java
# Java version     : 1.7.0_55
# Java home path   : /usr/lib/jvm/java-7-openjdk-amd64/jre
# Java compiler    : /usr/bin/javac
# Java headers gen.: /usr/bin/javah
# Java archive tool: /usr/bin/jar

然后我尝试运行R并加载rJava并得到以下错误:

R
> library(rJava)
Error : .onLoad failed in loadNamespace() for 'rJava', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
