重新安裝Ubuntu後JOGL不工作

Question

我有一個完整的工作項目在Ubuntu 9與日食。現在我已經安裝了Ubuntu 10.10，取回備份，下載Eclipse並嘗試運行該項目。

項目文件夾根本沒有改變！ 但現在不工作：

Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: no gluegen-rt in java.library.path

如果我去「項目屬性> Java構建路徑>庫」 gluegen-rt.jar中和jogl.jar都存在，我沒有編譯錯誤（」 進口javax.media.opengl.GLAutoDrawable;「沒有錯誤，所以類正確加載我認爲）

我試圖從突觸也安裝JOGL。

這裏完整的錯誤堆棧跟蹤：

Answer 1

我發現這個問題！

ECLIPSE SAVE絕對路徑外部JAR

在Eclipse項目屬性 - > Java構建路徑，去你的圖書館，找到gluegen-rt.jar中，展開它，然後單擊本地庫位置並輸入JOGL下載附帶的本地庫的位置。

在重新安裝Ubuntu後，我改變了我的主文件夾結構。

Answer 2

這幫助我弄清楚如何讓Eclipse使用OpenGL的Processing Libraries（http://processing.org）。我知道處理有它自己的編輯器，但它不是很豐富。

所以我有這個錯誤：

Exception in thread "Animation Thread" java.lang.UnsatisfiedLinkError: no gluegen-rt in java.library.path 

，所以我不得不右鍵點擊上的「工程資源管理器」的jogl.all.jar jar文件，點擊「屬性」，點擊「本地庫「並設置」位置路徑「。

我的位置路徑是：

/home/username/Desktop/processing-2.0a4/modes/java/libraries/opengl/library/linux32

之後，它的工作完美！
