这真的让我很困惑,因为我已经尝试了关于类路径和其他各种事情的一切可能。我在windows、linux和IDE中尝试过各种不同的命令提示符,但似乎没有什么帮助。总是相同的错误。任何见解都会有所帮助。
尝试使用以下命令运行javah时,我遇到以下错误:
javah -jni -cp jna-3.0.9.jar:java.nio.*:java.util.* CameraInterfaceLibrary
Error: Could not find class file for 'CameraInterfaceLibrary'.
我真的被困在这里了。我只是不明白为什么它拒绝生成头文件。无论我做什么,它总是说找不到类文件。我只是感到困惑。我已经尝试过更简单的例子,但对于真实的代码,它不起作用。
代码如下:
import com.sun.jna.Native;
import com.sun.jna.NativeLibrary;
import com.sun.jna.Pointer;
import com.sun.jna.Structure;
import com.sun.jna.win32.StdCallLibrary;
import java.nio.ByteBuffer;
import java.util.Arrays;
import java.util.List;
