在RHEL6上安装rJava：即使使用相同的Java路径，我也会得到：错误：一个或多个JNI类型与相应的本机类型

我在Linux服务器RHEL6上工作，我安装了anaconda。我有以下设置

 conda-env version : 4.3.13
 conda-build version : 2.1.4
 python version : 2.7.13.final.0
 rpy2 : 2.8.5

我安装了rpy2以在python中使用R.但是随着用conda安装的R版本我有问题安装＆＃34; rJava＆＃34;。 

checking whether Java run-time works... yes
checking whether -Xrs is supported... yes
checking whether JNI programs can be compiled... yes
checking JNI data types... configure: error: One or more JNI types differ from the corresponding native type. You may need to use non-standard compiler flags or a different compiler in order to fix this.
ERROR: configuration failed for package 'rJava'

我在同一台机器上安装了我的独立版本的R，我没有问题，所以我知道我安装了正确的版本。

对于我使用相同R版本的2种不同设置（带有con的R的独立R），我有相同的Java版本

 java -version
openjdk version "1.8.0_121"
OpenJDK Runtime Environment (build 1.8.0_121-b13)
OpenJDK 64-Bit Server VM (build 25.121-b13, mixed mode)

对于这两种设置，以下变量不会退出

R_JAVA_LD_LIBRARY_PATH
JAVA_HOME

定义。 PATH与独立版非常相似：

PATH=/opt/ccda/anaconda2/bin:/opt/opennlp/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

对于安装了conda的R，我有：

PATH=/opt/ccda/anaconda2/envs/py27CCA/bin:/opt/ccda/anaconda2/bin:/opt/ccda/anaconda2/bin:/opt/opennlp/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

这里是编译期间的信息。对于独立的R版本：

interpreter : '/usr/bin/java'
archiver    : '/usr/bin/jar'
compiler    : '/usr/bin/javac'
header prep.: '/usr/bin/javah'
cpp flags   : '-I/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.121-0.b13.el6_8.x86_64/jre/../include -I/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.121-0.b13.el6_8.x86_64/jre/../include/linux'
java libs   : '-L/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.121-0.b13.el6_8.x86_64/jre/lib/amd64/server -ljvm

对于使用conda安装的R版本：

interpreter : '/usr/lib/jvm/java/jre/bin/java'
archiver    : '/usr/lib/jvm/java/jre/../bin/jar'
compiler    : '/usr/lib/jvm/java/jre/../bin/javac'
header prep.: '/usr/lib/jvm/java/jre/../bin/javah'
cpp flags   : '-I/usr/lib/jvm/java/include -I/usr/lib/jvm/java/include/linux'
java libs   : '-L/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.121-0.b13.el6_8.x86_64/jre/lib/amd64/server -ljvm'

我尝试使用相同的路径：

export JAVA_HOME=/usr/lib/jvm/jre-1.8.0-openjdk.x86_64/bin/java
export R_JAVA_LD_LIBRARY_PATH=${JAVA_HOME}/lib/amd64/server
export JAVA_CPPFLAGS="-I/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.121-0.b13.el6_8.x86_64/jre/../include -I/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.121-0.b13.el6_8.x86_64/jre/../include/linux"
顺便说一下：

/usr/bin/java -> /etc/alternatives/java
/etc/alternatives/java -> /usr/lib/jvm/jre-1.8.0-openjdk.x86_64/bin/java

但重新运行后：

 R CMD javareconf

并重新编译我得到相同的错误，而路径现在看起来一样：

interpreter : '/usr/bin/java'
archiver    : '/usr/bin/jar'
compiler    : '/usr/bin/javac'
header prep.: '/usr/bin/javah'
cpp flags   : '-I/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.121-0.b13.el6_8.x86_64/jre/../include -I/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.121-0.b13.el6_8.x86_64/jre/../include/linux'
java libs   : '-L/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.121-0.b13.el6_8.x86_64/jre/lib/amd64/server -ljvm'

所以我不明白这意味着什么＆＃34;一个或多个JNI类型不同＆＃34;我应该在道路和旗帜上让它发挥作用。

我不明白，因为我不太了解错误信息的含义。我尝试了与类似问题相关的各种线程的所有建议。

编辑：使用导出

LD_LIBRARY_PATH=$JAVA_HOME/lib/amd64:$JAVA_HOME/lib/amd64/server

解决部分问题（在这种情况下不再需要JAVA_HOME）但我还有其他问题：

  • 在这种情况下不使用-m64标志（当它与独立的R版本一起使用时）

  • / usr / bin / ld：找不到-liconv

但是图书馆存在：

/opt/ccda/anaconda2/envs/py27CCA/lib/libiconv.so
/opt/ccda/anaconda2/envs/py27CCA/lib/libiconv.so.2
/opt/ccda/anaconda2/envs/py27CCA/lib/libiconv.so.2.5.1
/opt/ccda/anaconda2/envs/py27CCA/lib/preloadable_libiconv.so

但可能不在使用的路径中，所以我现在需要解决这个问题。

1 个答案:

答案 0 :(得分：1)

确保使用指向JDK的显式设置重新配置R环境。

确保JAVA_HOME指向JDK 

export JAVA_HOME=your_JDK_installation

然后，重新配置R并明确传递所有位置

sudo R CMD javareconf \
JAVA_HOME=${JAVA_HOME} \
JAVA=${JAVA_HOME/bin/java \
JAVAC=${JAVA_HOME}/bin/javac \
JAVAH=${JAVA_HOME}/bin/javah \
JAR=${JAVA_HOME}/bin/jar \
JAVA_LD_LIBRARY_PATH=${JAVA_HOME}/jre/lib/server \
JAVA_CPPFLAGS="-I${JAVA_HOME}/include -I${JAVA_HOME}/include/linux"

然后，尝试在R

之外配置rJava 
curl https://cran.r-project.org/src/contrib/rJava_0.9-8.tar.gz -o rJava_0.9-8.tar.gz
tar zxf rJava_0.9-8.tar.gz
cd rJava
./configure

如果有效，您应该能够从R

中的来源安装它

install.packages("rJava", type="source")
