This should work similar to the python package we use in rocon_console.

A hint on how to do the checks for an appropriate terminal is on stack overflow here.

Having them configured in place mucks up parallel builds (cross compiling and such).

The cotire module is just using regular cmake variables to guard - and these go out of scope, so it gets included by every package.

Make proper cached variables to guard...

Hello,

I am trying building files using catkin, which is used for Robotic OS, that uses CMAKE to build files. (I also attached a screenshot)

While I am building the files, the error below occurred.

Could you share why this error occurs and how to resolve this error, please?

It would be great to get this released into Melodic to start the process of getting the turtlebot2 repositories released there. Thanks!

Currently a mess inside ecl_io and I don't think it exports the correct windows librarys for msvc or mingw right now.

I'm trying to install the turtulebot_simulator on OSX and ecl_time_lite is failing to build.

@stonier

Macros defined in ecl/config/ecl.hpp need to be fixed up when we attack mingw/msvc support again.

Hi,

It would be nice to have a ros2-ardent branch to integrate PR for ros2, as #12
