致命错误:jni.h:安装jPype时没有此类文件或目录 [英] Fatal error: jni.h: No such file or directory while installing jPype

问题描述

我正在尝试在Ubuntu 13.04上安装JPype.我已经安装了Oracle Java 1.7.但是，当我这样做时，会出现以下错误:

I am trying to install JPype on Ubuntu 13.04. I have Oracle Java 1.7 installed. But when I do so, I get the following error:

src/native/common/include/jpype.h:45:17: fatal error: jni.h: No such file or directory

与很多关于stackoverflow的类似问题不同，该文件不在我的系统中，即

Unlike a lot of similar questions on stackoverflow, the file isn't present on my system i.e.

locate jni.h

不返回任何内容.是的，在发出上述命令之前，我已经运行过sudo Updatedb.

returns nothing. Yes, I have run sudo updatedb before issuing above command.

推荐答案

您已经安装了JRE而不是JDK.

You have installed a JRE and not a JDK.

要编译JNI本机代码，您需要安装JDK，该JDK带有适当的jni.h标头以及特定于操作系统的标头.

To compile JNI native code, you need to install a JDK, which comes with the appropriate jni.h header, as well as the OS specific headers.

执行此操作时，将包含路径更新为

When you do that, update your include path to

-I <path_to_jdk>/include -I <path_to_jdk>/include/linux
