linux - Planetlab 平台上的 Azureus/Vuze BitTorrent 客户端

Question

我正在开发名为 Planetlab 的测试平台的节点(64 位)。 java 路径已设置，简单的 jar 文件正在运行。我必须在此节点上运行 Azureus/Vuze bittorrent 客户端。它通过提取 Vuze 的安装程序 tar 文件然后使用命令“./vuze”在 Ubuntu 上运行。当我尝试在节点上运行它时，我遇到了这些:

Auto-scanning for GRE/XULRunner.  You can skip this by appending the GRE path to LD_LIBRARY_PATH and setting MOZILLA_FIVE_HOME.
Browser check failed with: Could not initialize class org.eclipse.swt.widgets.Display
Can't create browser.  Will try to set LD_LIBRARY_PATH and hope Vuze has better luck.

这是什么原因呢？

Answer 1

原因是这样的:

    /home/ku_green/.swt/lib/linux/x86/libswt-pi-gtk-4403.so: libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory

SWT 需要 GTK 库，但您的系统上不存在它们。具体来说，找不到 libgtk-x11-2.0.so.0。

您需要install this system library using yum .

首先找到包含该库的包:

yum whatprovides */libgtk-x11-2.0.so.0

然后安装它指示的软件包。

yum install gtk2
