Question

我跟随＆＃34; https://netbeans.org/kb/docs/cnd/beginning-jni-linux.html＆＃34;针对JNI的Netbeans教程，但是当我构建项目时，我在Netbeans输出中得到了这个错误：

cd 'E:\Janhavi\Projects\JNIDemoCdl'

这是我对JNI的第一次尝试，我现在有点困惑。请让我知道这是什么错误？提前谢谢。

你的JNIDemoCdl正在调用make in cygwin64。这就是你在每个目录名之前得到/cygdrive的原因，因为它们是在cygwin挂载的驱动器中执行的。

我认为问题出在您最终获得的“程序文件”中的空间：

cc1：致命错误：/ cygdrive / C / Program Files / Java / jdk1.7.0_79 / include：没有这样的文件或目录编译终止。

尝试将/Java/jdk1.7.0_79/存储在名称中没有空格的目录下，然后重新构建项目。

构建时出现JNI错误
