An extra null pointer check is not needed in functions like the following.

• gps_handler
• RecordingManager
• TransitionUndefinedException

The function "exit" does not belong to the list of async-signal-safe functions.
I guess that a different program design will be needed for your function "sighandler".

Would you like to add more error handling for return values from functions like the following?

• printf ⇒ TimesyncHandler::handleMessage
• pthread_create ⇒ main

Hi, your algorithm is very innovative and has a great influence to my research.
However, i find that the pushbroom stereo algorithm can not detect some body parts, such as legs or head, while a person as an obstacle. So i really want to know what specific environment is best for this algorithm.
Is there a standard for obstacle selection? Can you tell me how to choose them to make me continue my research?
Thanks you for your help!

Hi I am super new to LCM an just went through homepage about the introduces and tutorials. But it seems no detail tutorials. I have experiences in ROS but want to use some small framework to develop our project. Algorithm processed in onboard computer( arm ubuntu) with copter to avoid obstacles.

Can I ask questions about framework which integrated in your whole project. Is that LCM connected every module together like several ROS nodes with pub/sub mechanism. It seems that LCM use broadly in multi-mechines communication not computer threads.

I try to use the flight controller API (drone-python) to communicate between onboard computer and Pixhawk which uses APM copter firmware. Because that's more stable and functional API. And stereo-camera with opencv to acquire obstacle data in c++, like depth map, etc. I wan to use LCM sub/pub message mechanism to wrap this two modules. maybe more modules in the future. Is that possible?

Please correct my misunderstanding and give me some suggestions. Thanks for your help.

i clone the libbot , and when i run the sudo make BUILD_PREFIX=/usr/local -j
there is two mistake about bot2-param how can i figure it out ?

Hello, I'm new to this. I'm trying to build your project by doing things like ./build-all, and make in the different directories but I can't get it to work. Could you explain how to build and run your project?

i install everything , but when i use the command ./build-all -j , i meet some wrong .

rek@rek:~/realtime$ ./build-all -j
