Eclipse无法加载SWT库

Question

每次我尝试在Ubuntu 12.04中打开Eclipse时,我都会收到一个不满意的链接错误,它将无法打开.我最近安装了java JDK和Android SDK,这可能是问题吗？我按照本教程.

这是日志信息:

我尝试卸载并重新安装,并删除~/.eclipse目录但它仍然无法正常工作

Answer 1

在我的Ubuntu 12.04 32位上.我编辑命令:

ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86/

并在Ubuntu 12.04 64位尝试:

ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86_64/

Answer 2

解决了:

因为我已经安装了Oracle Java 7,所以它已将默认Java更改为Oracle Java 7,但它需要是Open JDK.

要修复,打开终端并输入

sudo update-alternatives --config java

这将显示不同类型的Java列表.只需选择Open JDK即可.

Answer 3

只需指定库的路径:

echo "-Djava.library.path=/usr/lib/jni/" >> /etc/eclipse.ini

Answer 4

在我的情况下,我/usr/lib/jni完全错过了目录.固定的

sudo apt-get install libswt-gtk-3-jni libswt-gtk-3-java

之后不需要符号链接.Eclipse正常启动.

Answer 5

无法加载库：/home/tom/.swt/lib/linux/x86_64/libswt-gtk-3740.so
无法加载库：/home/tom/.swt/lib/linux/x86_64/libswt-gtk.so

看起来这些库应该位于 .swt/lib/linux/x86_64/ 如果没有，你可以尝试这个命令：

找到 libswt-gtk.so

这应该会发现库将整个目录复制到 /home/tom/.swt/lib/linux/x86_64

Answer 6

对于适用于 Linux 的 Windows 子系统 (WSL)，您需要

apt install libswt-gtk-4-jni

如果您没有 OpenJDK 8，您还需要

apt install openjdk-8-jdk
