Linux下实现JNI期间发生的错误……【未解决】

浏览数：167 / 时间：2015年06月20日

　　万能的博客园啊……希望发完这个问题记录后能尽快发现自己的错误%>_<%

问题描述：

　　在linux下通过gcc命令编译c文件生成动态链接库.so文件时报错。之前命令内导入了jni.h和jni_md.h所在路径，报错；之后将这两个头文件复制到/usr/include/路径下，

导入，仍报错。

　　检查了一下JAVA_HOME路径、java、javac命令都能正常运行，普通的.c文件也能正常编译。根据报错的提示来看是.h文件中的jint、jbyte...未定义。。。不过根据我

浅薄的认知，这些变量不就在jni.h里定义的么……真是头痛。。。
