Pcl: How to display the debug info in console?

[Micalson]

Hello, thank you for your nice code.
I have a question in debugging pcl source code. There are many places using "pcl::console::print (pcl::console::L_DEBUG, __VA_ARGS__)", but I could see nothing in cosole. How to display the debug info? (any macro definition?)
Thank you for your reply.

If you add this command to the start of your program, PCL will show all debug/logging: pcl::console::setVerbosityLevel(pcl::console::L_VERBOSE);. Here is the documentation.

Thank you for your reply. I will try it.

If you wish to not modify your code (for any reason), you can also use environment variables to achieve the same result.

PCL_VERBOSITY_LEVEL can be ALWAYS, ERROR, WARN, INFO, DEBUG, VERBOSE as and when needed.

There's another variable that might be helpful if you're using some other facility to log your logs: PCL_CLICOLOR_FORCE. If it's set to any valid string, it'll force the output to always be colored.

PS: Please close this issue once you're satisfied with the answers
