致命错误:jni_md。h:没有这样的文件或目录#包括“jni_md.h”

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

在ubuntu中执行gcc命令生成一个或。

$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.

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

我已经给出了生成一个文件的例子，但是同样的问题也被观察到了。

But same gcc command works for openjdk7/oraclejdk7.

但是，同样的gcc命令也适用于openjdk7/oraclejdk7。

What is the issue here?

这里的问题是什么?

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

我认为您没有添加包括jni_md的目录。h是依赖于平台的。

Try

试一试

$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

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

如果你不知道jni_md在哪里。h是,使用:

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