我正在尝试在 OpenSUSE 11.3 上的R 2.14.1-9.1上安装 rJava 包。我见过this问题，但它适用于Ubuntu。我已经安装了Sun JDK并重新配置了系统以使用它。
admin@linux-nb3w:~> java -version
java version "1.6.0_29"
Java(TM) SE Runtime Environment (build 1.6.0_29-b11)
Java HotSpot(TM) Client VM (build 20.4-b02, mixed mode)
admin@linux-nb3w:~>
编辑1：
更新了JDK和JRE。现在运行install.packages("rJava")时出现略有不同的错误，我得到以下输出错误（新错误已发布，结尾为粗体）：

我确实将R CMD javareconf作为root运行。它使cpp标志字段为空。我知道这是失败的一个原因，但不知道如何解决它。
我尝试过这个带有dependencies = TRUE选项的安装命令，并且还明确指定了repo（例如repo =“blah blah”）。没有任何效果。
我不知道如何对OpenSUSE进行更新。但是对于SUSE来说，看起来没有简单的方法可以做到这一点，与Ubuntu不同，其中明确给出了步骤here。
感谢任何帮助。

尽管正在运行update-alternatives --config javac，但JAVA_HOME未更新。因此我手动设置：
export JAVA_HOME=/usr/lib/jvm/java-1.6.0-sun-1.6.0.u6
您必须以root运行以上命令。
然后跑R CMD javareconf。有一些进步，安装超出了以前失败的地方。但它仍然给我以下错误：

然后根据错误中的建议，安装R-devel-rpm，如下所示：
zypper install R-patched R-patched-devel
（将上述命令作为root运行）
在此之后，运行R并且“install.package（”rJava“）”工作。
对于一个真正的问题，差不多5个小时的挫折和4个投票......但终于得到了解决！ ：）

真棒。在Gentoo下也是如此。 做
env | grep JAVA
检查您的环境。
