构建时JNI错误

JNI error while building

我遵循"https://netbeans.org/kb/docs/cnd/beginning-jni-linux.html" Netbeans教程的JNI，但当我构建项目时，我在Netbeans输出中得到这个错误:

这是我第一次尝试使用JNI，我有点卡在这一点上。请告诉我哪里出错了?

您的JNIDemoCdl正在cygwin64内部调用make。这就是为什么在cygwin挂载的驱动器中执行每个目录名称时，会在它们前面显示/cygdrive的原因。

我认为问题在于'程序文件'中的空间，您最终得到:

cc1: fatal error:/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间的目录下并重新构建项目
