Can not identify drake related class

[hughhugh]

Hi, @andybarry I have git clone and complied drake in R2017a and Ubuntu 16.04. I tried examples in drake like Quadrotor and Quadrotor2D, both works well. Then I git clone the simflight repository, it doesnot work. Log are as the following. From the console infos, there is something wrong with the drake class. In the Quadrotor example, the class "drake.util.BotLCMGLClient" is also been used. So could you help figure it out? Thank you very much.

'LCM: Disabling IPV6 support LCM: TTL set to zero, traffic will not leave localhost. Undefined variable "drake" or class "drake.util.BotLCMGLClient".

Error in DrawTrajectoryLcmGl (line 32) lcmgl = drake.util.BotLCMGLClient(lcm.lcm.LCM.getSingleton(), lcmgl_name);

Error in BuildTrajectoryLibrary (line 15) [x0, u0, lib] = FindTrimDrake(p, lib, gains_ti);'

Drake has changed a lot since I wrote this code. Try checking out a revision of Drake from around Dec 2015.

Hi, @andybarry I have build the last_sha_with_windows_support. The visualizer can be loaded, but there are still some errors. I have tried 'ccmake ..' command to set Drake. Could you display me the configure used? Thank you.

1.Find all "drake.util.BotLCMGLClient" in the drake, and change it to "drake.matlab.util.BotLCMGLClient". 2.Find all "obj.p.playback" or "playback", and comment it.

which verison of drake ? Can u explain it? thanks. @dayanmayi @andybarry @hughhugh
