Ubuntu: SWT App Can't Load GTK Library
提问by Nifty255
I have supplied the Linux SWT jar and packaged my app in Eclipse to include swt.jar inside my app's jar. When I try to run it on Ubuntu, I get the following error text (posting only cause):
我提供了 Linux SWT jar 并将我的应用程序打包在 Eclipse 中，以将 swt.jar 包含在我的应用程序 jar 中。当我尝试在 Ubuntu 上运行它时，我收到以下错误文本（仅发布原因）：
Caused by: java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons:
no swt-pi-gtk-4234 in java.library.path
no swt-pi-gtk in java.library.path
/home/nifty/.swt/lib/linux/x86/libswt-pi-gtk-4234.so: libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory
Can't load library: /home/nifty/.swt/lib/linux/x86/libswt-pi-gtk.so
引起：java.lang.UnsatisfiedLinkError：无法加载 SWT 库。原因：
java.library.path 中没有 swt-pi-gtk-4234
java.library.path 中没有 swt-pi-gtk
/home/nifty/.swt/lib/linux/x86/libswt-pi-gtk-4234.so：libgtk-x11-2.0.so.0：无法打开共享对象文件：没有这样的文件或目录
无法加载库：/home/nifty/.swt/lib/linux/x86/libswt-pi-gtk.so
This indicates to me it can't load a GTK file, but anything beyond that, and I'm at a loss. I'm only using Ubuntu to test my app, so I know very little.
这向我表明它无法加载 GTK 文件，但除此之外的任何内容，我都不知所措。我只使用 Ubuntu 来测试我的应用程序，所以我知道的很少。

Here is how I fix that missing lib on my Ubuntu 13.10 x86_64:

On my 64-bit Debian Wheezy/testing I solved it by doing
在我的 64 位 Debian Wheezy/testing 上，我解决了这个问题
apt-get install ia32-libs-gtk
(http://www.eclipse.org/forums/index.php/t/262868/). If your system isn't a 64-bit system then this suggestion is not applicable.

With latest Ubuntu (18.10), installing libswt-gtk-3-javafixed it.
To do so, from a terminal, type the command:
sudo apt install libswt-gtk-3-java
使用最新的 Ubuntu (18.10)，安装libswt-gtk-3-java修复了它。为此，请从终端键入命令：
sudo apt install libswt-gtk-3-java
For most updated version, I would suggest following link: https://packages.ubuntu.com/search?keywords=swt-gtk
对于大多数更新版本，我建议使用以下链接：https: //packages.ubuntu.com/search?keywords=swt-gtk

For more recent releases, if it says it can't find libgtk-3.so.0, the obvious package you need to apt-get installis libgtk-3-0. However, it seems on Ubuntu Zesty (17.04) there isn't such a package, so I needed to switch to Xenial (16.04). Artful and later should work too.
对于较新的版本，如果它说找不到libgtk-3.so.0，则您需要的明显软件包apt-get install是libgtk-3-0。但是，在 Ubuntu Zesty (17.04) 上似乎没有这样的包，所以我需要切换到 Xenial (16.04)。巧妙，后来也应该工作。
Also, the graphical Eclipse Installerwon't work without this.
此外，没有这个图形 Eclipse 安装程序将无法工作。
