无法使用位置 /home/ecm/oinstall/rcuHome/rcu/log/logdir.2011-12-26_09-54/rcu.log 初始化日志记录程序
使用以下位置初始化日志记录程序: /tmp/logdir.2011-12-26_09-54/rcu.log
Exception in thread “main” java.lang.UnsatisfiedLinkError: /home/ecm/oinstall/rcuHome/jdk/jre/lib/i386/xawt/libmawt.so: libXext.so.6: cannot open shared object file: No such file or directory
