Common build errors

Here are some common errors and workarounds (if found any) on either of your local machine / jenkins (buildfarm at ROS infra) / travis.

This is due to memory limitation of travis server.

WORKAROUND: Wait and re-trigger travis, as recommended (here).

(travis) test RESULT: FAIL

This is failure in the test, in the test, happens in for example https://github.com/start-jsk/rtmros_hironx/blob/ef440a46961917047e8c265e62067755aa67e891/hironx_ros_bridge/test/test_hironx.py#L494.

self.check_log_data(data, 6, 9, -135, -100.0)

means using data and index of 6, expected time is 9 sec and the angle moves from -135 to 100. This test fails when we rtc did not runs every 5 msec ???

WORKAROUND: This has been fixed in 1.0.21, please report error to https://github.com/start-jsk/rtmros_hironx/issues

(rostest/rtmtest) test fails with corbaserver using port 15005

When rostest fails no matter what value you use in launch files, look at Environment Variables RTCTREE_NAMESERVERS, which might be most likely set as 15005 (hrpsys default). In that case re-define it as you want:

$ unset RTCTREE_NAMESERVERS
$ export RTCTREE_NAMESERVERS=localhost:2809
