CMake Deprecation Warning at cmake/for_clients.cmake:15 (CMAKE_POLICY):
The OLD behavior for policy CMP0007 will be removed from a future version
of CMake.
The cmake-policies(7) manual explains that the OLD behaviors of all
policies are deprecated and that a policy should be set to OLD only under
specific short-term circumstances. Projects should be ported to the NEW
behavior and not rely on setting a policy to OLD.

WARNING: The host 'haiyuan' could not be looked up with /usr/local/mysql//bin/resolveip.
This probably means that your libc libraries are not 100 % compatible

This means that you should use IP addresses instead of hostnames

The problem could be conflicting information in an external
my.cnf files. You can ignore these by doing:
shell> scripts/mysql_install_db --defaults-file=~/.my.cnf
You can also try to start the mysqld daemon with:
shell> /usr/local/mysql//bin/mysqld --skip-grant --general-log &
and use the command line tool /usr/local/mysql//bin/mysql
to connect to the mysql database and look at the grant tables:
shell> /usr/local/mysql//bin/mysql -u root mysql
mysql> show tables;
Try 'mysqld --help' if you have problems with paths. Using
--general-log gives you a log in /data_linux/mysql/3306/data/ that may be helpful.

文章浏览阅读1.8k次。 路径规划问题是机器人学研究的一个重要领域，它是指给定操作环境以及起始和目标的位置姿态，要求选择一条从起始点到目标点的路径，使运动物体(移动机器人或机械臂)能安全、无碰撞地通过所有的障碍物而达到目标位置。路径规划从研究对象上可分为关节式机械臂和移动机器人。一般来讲前者具有更多的自由度，而后者的作业范围要更大一些，这两类对象具有不同的特点，因此在研究方法上略有不同。在V-rep学习笔记：机器人路..._collision pairs
