“无法加载 SWT 库”错误 - java.library.path 中没有 swt-pi4*

Question

我正在尝试运行基于 Eclipse 的应用程序，但由于尝试访问

libswt-pi4.so

、

libswt-pi4-gtk.so

和

libswt-pi4-gtk-4944r26.so

时出现错误而无法运行。顺便说一句，由于保密协议，我不会详细介绍该应用程序，但我相信这不应该成为问题，因为该问题似乎源于 Eclipse 基础。我使用的是 Linux Mint 21.2。

错误（稍作编辑）如下：

浏览类似问题，我发现帖子建议我安装

libswt-gtk-4-java

和

libswt-gtk-4-java

，我已经安装了。这并没有解决问题。之后，另一篇文章建议创建从

/usr/lib/jni/libswt-*

到

~/.swt/lib/linux/x86_64/

的链接（这确实是错误声称文件不存在的地方），但快速查看原始文件夹会发现所需的库也不存在：

alexandre:/usr/lib/jni$ l
libswt-atk-gtk-4944r26.so  libswt-awt-gtk-4944r26.so  libswt-gtk-4944r26.so  libswt-pi3-gtk-4944r26.so

~/.swt/lib/linux/x86_64/

默认只有一个文件，即

libswt-pi3-gtk-4944r26.so

。

有关于我可能丢失了哪些包裹的线索吗？谢谢您的宝贵时间。

对我来说，它有助于安装 libgtk-3-0（在 Debian 12 上）。
