使用LLVM运行javacpp预设时的UnsatisfiedLinkError

Question

我正在尝试为LLVM使用javacpp-presets，但似乎有一个链接时间问题:每当我尝试运行我的程序时，我都会得到一个错误

"Exception in thread "main" java.lang.UnsatisfiedLinkError: no jniLLVM in java.library.path" I'm on a Windows 10 machine.

下面是我的代码

package baecompiler;
//boilerplate code https://github.com/bytedeco/javacpp-presets/tree/master/llvm
//so we can play with LLVM code generation
// General stuff
import org.bytedeco.javacpp.*;

// Headers required by LLVM
import static org.bytedeco.javacpp.LLVM.*;

public class LLVMExperiment {

    public static void main (String[] args) {

        BytePointer error = new BytePointer((Pointer)null); // Used to retrieve messages from functions

        LLVMLinkInMCJIT(); //the line it fails on

        ....

Answer 1

在命令行中添加-Djava.library.path=x，其中x是jniLLVM.dll文件的完整路径。
