Ubuntu 20.04下Windriver Workbench报java.lang.UnsatisfiedLinkError错误求助

背景 #

通过scp从另一台服务器复制Windriver目录到本地Linux服务器，该操作在其他服务器可正常运行。启动Windriver Workbench后GUI能显示，但选择工作区目录后报错，提示查看日志。

本地Java版本 #

openjdk version "1.8.0_392"
OpenJDK Runtime Environment (build 1.8.0_392-8u392-ga-1~20.04-b08)
OpenJDK 64-Bit Server VM (build 25.392-b08, mixed mode)

之前的问题及处理 #

曾遇到共享对象缺失问题，报错如下：

no swt-pi-gtk in java.library.path /root/.swt/lib/linux/x86/libswt-pi-gtk-3836.so: libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory Can't load library: /root/.swt/lib/linux/x86/libswt-pi-gtk.so

安装相关库后GUI可正常启动。

已尝试操作 #

安装Windriver官网提及的依赖库：

sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib \ build-essential chrpath socat cpio python python3 python3-pip python3-pexpect \ xz-utils debianutils iputils-ping libsdl1.2-dev xterm

针对java.lang.UnsatisfiedLinkError错误，可按以下步骤排查修复：

1. 匹配Java版本 #

从日志可见，Windriver Workbench实际调用的是Java 1.6.0_21，但本地系统默认是OpenJDK 1.8.0_392。老版本Windriver对Java版本兼容性要求严格，需强制Workbench使用对应版本：

• 下载Oracle JDK 1.6.0_21并解压到本地目录（如/opt/jdk1.6.0_21）
• 修改Windriver启动脚本（如wrwb），在开头添加环境变量配置：

  export JAVA_HOME=/opt/jdk1.6.0_21
  export PATH=$JAVA_HOME/bin:$PATH
  

2. 补全32位系统依赖 #

日志中BootLoader显示ARCH=x86，说明Workbench是32位程序，需安装32位基础库：

sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 libgtk2.0-0:i386 libxtst6:i386

3. 修复目录权限 #

复制的Windriver目录可能存在权限缺失，执行以下命令修复：

sudo chmod -R 755 /path/to/windriver
sudo chown -R $USER:$USER /path/to/windriver

4. 重置工作区配置 #

若上述步骤无效，可尝试重置工作区：

• 删除原工作区目录下的.metadata文件夹
• 重新启动Workbench并选择该工作区
