致命错误:jni_md.h:没有这样的文件或目录#include"jni_md.h" [英] fatal error: jni_md.h: No such file or directory #include "jni_md.h"

问题描述

在ubuntu上执行gcc命令以生成JNI的.a或.so文件时，openjdk 8/oraclejdk8的错误均降至错误以下.

While executing gcc command on ubuntu for generating .a or .so file for JNI, getting below error for both openjdk 8 / oraclejdk8.

$gcc -I/usr/lib/jvm/java-8-openjdk-amd64/include -c MainImpl1.c -o MainImpl1.o

In file included from MainImpl1.c:1:0:
/usr/lib/jvm/java-8-openjdk-amd64/include/jni.h:45:20: fatal error: jni_md.h: No such file or directory
 #include "jni_md.h"
                ^
compilation terminated.

$gcc -I/usr/lib/jvm/java-8-oracle/include -c MainImpl1.c -o MainImpl1.o

In file included from MainImpl1.c:1:0:
/usr/lib/jvm/java-8-oracle/include/jni.h:45:20: fatal error: jni_md.h: No such file or directory
 #include "jni_md.h"
                ^
compilation terminated.

我已经给出了生成.a文件的示例，但是在生成.so文件时也遇到了同样的问题.

I have given example for generating .a file, but same issue observed for .so file generation also.

但是相同的gcc命令适用于openjdk7/oraclejdk7.

But same gcc command works for openjdk7/oraclejdk7.

这是什么问题?

推荐答案

我认为您没有添加包含jni_md.h的包含目录，其中jni_md.h是

I think that you do not added include directory that includes jni_md.h which is platform dependent.

尝试

$gcc -I/usr/lib/jvm/java-8-openjdk-amd64/include -I/usr/lib/jvm/java-8-openjdk-amd64/include/linux -c MainImpl1.c -o MainImpl1.o

或

$gcc -I/usr/lib/jvm/java-8-oracle/include -I/usr/lib/jvm/java-8-oracle/include/linux -c MainImpl1.c -o MainImpl1.o

如果您不知道jni_md.h在哪里，请使用find:

If you don't know where jni_md.h is, use find:

find / -name jni_md.h 2> /dev/null
