在 Leiningen/Clojure 中使用 lwjgl [英] Using lwjgl in Leiningen/Clojure

问题描述

(1) (println (. System getProperty "java.library.path"))

这给了我一个 java 寻找本机扩展的地方的列表.

This gives me a list of places java looks for native extensions.

然后，我将 lwjgl 原生扩展放在那里.

Then, I took the lwjgl native extensions, and put them there.

(*) setting :native-path
(*) setting :native-dependencies

问题

我的设置:

(lein deps; echo "====="; cat project.clj; echo "====="; cat src/main.clj; echo "====="; lein repl) &> log

日志"的内容

    Copying 10 files to /Volumes/ramdisk/fail/lib
=====
(defproject
  mincase "0.0.1"
  :dependencies [[org.clojure/clojure "1.4.0"]
                 [org.lwjgl.lwjgl/lwjgl "2.8.2"] ]
  :repositories {"local" "/Users/x/z/maven_repo"}
  :jvm-opts ["-Xms4g"  "-Xmx4g"]
  :repl-init main
  )

REPL started; server listening on localhost port 31235
UnsatisfiedLinkError no lwjgl in java.library.path  java.lang.ClassLoader.loadLibrary (ClassLoader.java:1860)
clojure.core=> 

注意——我已经做了一个lein deps"，所以 lwjgl 库已经被拉进了 maven.我不明白的是:

Note -- I had already done a "lein deps", so the lwjgl library has been pulled into maven. What I don't understand are:

(*) how do I get access to lwjgl from Clojure?
(*) more importantly, how do I debug which step this whole thing has gone wrong at?

$ 查找库

lib
lib/clojure-1.4.0.jar
lib/jinput-2.0.5.jar
lib/jinput-platform-2.0.5-natives-linux.jar
lib/jinput-platform-2.0.5-natives-osx.jar
lib/jinput-platform-2.0.5-natives-windows.jar
lib/jutils-1.0.0.jar
lib/lwjgl-2.8.2.jar
lib/lwjgl-platform-2.8.2-natives-linux.jar
lib/lwjgl-platform-2.8.2-natives-osx.jar
lib/lwjgl-platform-2.8.2-natives-windows.jar

看来 lwjgl 已经被拉进来了.

So it appears that lwjgl has been pulled in.

我应该尝试哪些步骤来找出我出错的步骤?

What are the steps I should try to figure out which step I went wrong on?

谢谢！

推荐答案

您的 LD_LIBRARY_PATH 看起来有问题.您是否包含正确的 .dll 或 .so 文件?

Looks like a problem with your LD_LIBRARY_PATH. Are you including the correct .dll or .so files?

您可能需要在 project.clj 中添加类似 :native-dependencies [[lwjgl "2.8.2"]] 的内容.

You probably need to add something like :native-dependencies [[lwjgl "2.8.2"]] to your project.clj.

或者，您可以尝试从 shell 设置正确的值:

Alternatively, you could try setting the right value from your shell:

export LD_LIBRARY_PATH=/home/username/lwjgl-2.8.2/native/linux/
