我无法运行eclipse.如何解决这个问题并运行eclipse.

Answer 1

尝试使用以下命令

• 64位系统: ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86_64/

• 32位系统: ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86/

Answer 2

通过复制libswt文件来解决这个问题~/.swt/lib/linux/x86(or x86_64)

对于32位:

/bin/cp /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86/

对于64位:

/bin/cp /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86_64/

Answer 3

当我试图在64位linux下启动32位Eclipse时,我遇到了这个错误.安装ia32-libs软件包后问题得以解决.

Answer 4

您正在混合 64 位和 32 位。下载 64 位版本的 Eclipse 并使用 64 位版本的 Java 7。
