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

问题描述

解决方案

 （1）（println（。System getPropertyjava.library.path））
  

这给出了一个java寻找原生扩展名的地方列表。

然后，我把lwjgl原生扩展，并把它们放在那里。

没有为我工作的东西（可能是因为我错误地使用） h2>

 （*）设置：native-path 
（*）设置：native-dependencies 
  
 
 
 
问题
 
 
 
我的设置：
 （lein deps; echo=====; cat project.clj; echo=====; cat src / main.clj; echo =====; lein repl）&> log 
  
log的内容
 将10个文件复制到/ Volumes / ramdisk / fail / lib 
 ===== 
（defproject 
 mincase0.0.1
 ：dependencies [[org.clojure / clojure1.4.0] 
 [org.lwjgl.lwjgl / lwjgl2.8.2]] 
：repositories {local/ Users / z / maven_repo} 
：jvm-opts [-Xms4g-Xmx4g] 
：repl-init main 
）
 
 ===== 
（ns main 
（：import org.lwjgl.opengl.Display））
 ===== 
 REPL started;服务器侦听localhost端口31235 
 unsatisfiedLinkError否lwjgl在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库已经被拉入maven。我不明白是什么：
 （*）如何从Clojure访问lwjgl？ 
（*）更重要的是，我如何调试哪个步骤这整个东西出了问题？ 
  
 $ find lib 
  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- -osx.jar 
 lib / lwjgl-platform-2.8.2-natives-windows.jar 
  
所以看起来lwjgl已经被拉入了。
 
 
 
我应该尝试找出哪个步骤我错了？
 
 
 
谢谢！
解决方案
看起来像您的 LD_LIBRARY_PATH 。您是否包含正确的 .dll 或 .so 文件？
 
 
 
您可能需要向 project.clj 添加：native-dependencies [[lwjgl2.8.2]]  code>。
 
 
 
或者，您可以尝试从shell设置正确的值：
  export LD_LIBRARY_PATH = / home / username / lwjgl-2.8.2 / native / linux / 
  
 
Solution

(1) (println (. System getProperty "java.library.path"))
This gives me a list of places java looks for native extensions.

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

Things that didn't work for me (probably because I used them incorrectly)

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


Problem

My setup:
(lein deps; echo "====="; cat project.clj; echo "====="; cat src/main.clj; echo "====="; lein repl) &> log
contents of "log"
    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
  )

=====
(ns main
 (:import org.lwjgl.opengl.Display)) 
=====
REPL started; server listening on localhost port 31235
UnsatisfiedLinkError no lwjgl in java.library.path  java.lang.ClassLoader.loadLibrary (ClassLoader.java:1860)
clojure.core=> 
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?
$ find lib
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
So it appears that lwjgl has been pulled in.

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

Thanks!
解决方案
Looks like a problem with your LD_LIBRARY_PATH.  Are you including the correct .dll or .so files?

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

Alternatively, you could try setting the right value from your shell:
export LD_LIBRARY_PATH=/home/username/lwjgl-2.8.2/native/linux/
