我必须将本机C ++库映射到JNA,这是库头:
#ifndef WORMDLL_H
#define WORMDLL_H
#pragma once
#ifdef WORMDLL_EXPORTS
#define WORMDLL_API __declspec(dllexport)
#else
#define WORMDLL_API __declspec(dllimport)
#endif
#include "wormError.h"
typedef BYTE WORM_DATA;
WORMDLL_API WORM_ERROR worm_readData(const char* mountPoint, WORM_DATA *data,const unsigned int offset,const unsigned int numBlocks);
#endif
这是我用JNAeator制作的映射:
package test;
import com.ochafik.lang.jnaerator.runtime.LibraryExtractor;
import com.ochafik.lang.jnaerator.runtime.MangledFunctionMapper;
import com.sun.jna.Library;
import com.sun.jna.Native;
import com.sun.jna.NativeLibrary;
import com.sun.jna.Pointer;
import com.sun.jna.PointerType;
import java.nio.ByteBuffer;
public interface TestLibrary extends Library {
public static final String JNA_LIBRARY_NAME = LibraryExtractor.getLibraryPath("test", true, TestLibrary.class);
public static final NativeLibrary JNA_NATIVE_LIB = NativeLibrary.getInstance(TestLibrary.JNA_LIBRARY_NAME, MangledFunctionMapper.DEFAULT_OPTIONS);
public static final TestLibrary INSTANCE = (TestLibrary)Native.loadLibrary(TestLibrary.JNA_LIBRARY_NAME, TestLibrary.class, MangledFunctionMapper.DEFAULT_OPTIONS);
TestLibrary.WORM_ERROR worm_readData(String mountPoint, ByteBuffer data, int offset, int numBlocks);
public static class WORM_ERROR extends PointerType {
public WORM_ERROR(Pointer address) {
super(address);
}
public WORM_ERROR() {
super();
}
};
}
这是DependencyWalker找到的导出函数:
当我尝试使用此配置运行测试时,我得到了:
线程中的异常" main" java.lang.UnsatisfiedLinkError:错误 查找功能' worm_readData'
为什么JNA找不到函数名?
