[英]JNI unsatisfiedLinkError?
I am practising JNI and created the shared library file Samplelib.so. 我正在练习JNI并创建了共享库文件Samplelib.so。 I added the directory in which the library file is created, to the java.library.path and when I run the java file, I get java.lang.UnsatisfiedLinkError. 我将创建库文件的目录添加到java.library.path中,当我运行java文件时,我得到了java.lang.UnsatisfiedLinkError。 Here is my Sample.java. 这是我的Sample.java。
import java.util.*;
public class Sample{
public native int intmethod(int n);
public native String stringmethod(String s);
public static void main(String[] args) {
try{
//System.setProperty( "java.library.path", "/home/sudhagar/Project" );
System.load("libSample");
Sample sample=new Sample();
int sq=sample.intmethod(2);
String text=sample.stringmethod("JAVA");
System.out.println(sq);
System.out.println(text);
}
catch(UnsatisfiedLinkError e){
String property = System.getProperty("java.library.path");
StringTokenizer parser = new StringTokenizer(property, ";");
while (parser.hasMoreTokens()) {
System.err.println(parser.nextToken());
}
}
}
}
My Sample.c file, 我的Sample.c文件,
#include "Sample.h"
#include <string.h>
JNIEXPORT jint JNICALL Java_Sample_intmethod
(JNIEnv *env, jobject obj, jint n){
return n*n;
}
JNIEXPORT jstring JNICALL Java_Sample_stringmethod
(JNIEnv *env, jobject obj, jstring n){
return n;
}
void main(){}
I used following command to create the create the shared library, gcc -shared -I/.../include -I/.../include/linux -o libSample.so Sample.c 我用以下命令创建了创建共享库,gcc -shared -I /.../ include -I /.../ include / linux -o libSample.so Sample.c
Use 采用
System.loadLibrary("Samplelib");
instead of 代替
System.load("Samplelib");
