無法在RedHat 5（R 3.3.0）中安裝rJava軟件包| 無法編譯JNI程序

Question

當我運行install.packages（“ rJava”）時

錯誤：-

checking whether siglongjmp is declared... yes
checking Java support in R... present:
interpreter : '/usr/bin/java'
archiver    : '/usr/bin/jar'
compiler    : '/usr/bin/javac'

configure: error: One or more Java configuration variables are not set.
Make sure R is configured with full Java support (including JDK). Run
R CMD javareconf
as root to add Java support to R.

If you don't have root privileges, run
R CMD javareconf -e
to set all Java-related variables and then install rJava.

我跑了R CMD javareconf -e

/usr/bin/ld: cannot find -lcurl

make: *** [conftest.so] Error 1
Unable to compile a JNI program

下列Java變量已導出：

JAVA_HOME JAVA JAVAC JAVAH JAR JAVA_LIBS JAVA_CPPFLAGS JAVA_LD_LIBRARY_PATH

同時導出JAVA_HOME = jdk_path

有人可以幫我嗎？

在您的工作站中安裝最新的Java版本，並在Rstudio中設置Java主頁，我認為這可能有效

Sys.setenv(JAVA_HOME="C:\\Program Files\\Java\\jre7")
