Issue details

I am unable to build the mavros package. I was following the source install tutorial on this page https://github.com/mavlink/mavros/blob/ros2/mavros/README.md

I run into errors at the colcon build line. Where mavros_msgs fails to build due to a CMAKE error. I am not quite sure how to solve this issue. Thank you!

MAVROS version and platform

Mavros: 2.3.0 ROS: Foxy Ubuntu: 20.04

Autopilot type and version

*Cant get far enough to test

[ ] ArduPilot [ ] PX4

Version: ?3.7.1?

Output of colcon build command

Starting >>> mavlink Starting >>> mavros_msgs --- stderr: mavros_msgs
CMake Error at CMakeLists.txt:14 (find_package): By not providing "Findament_cmake.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "ament_cmake", but CMake did not find one.

Could not find a package configuration file provided by "ament_cmake" with any of the following names:

ament_cmakeConfig.cmake
ament_cmake-config.cmake

Add the installation prefix of "ament_cmake" to CMAKE_PREFIX_PATH or set "ament_cmake_DIR" to a directory containing one of the above files. If "ament_cmake" provides a separate development package or SDK, be sure it has been installed.

Have you done source /opt/ros/foxy/setup.bash as suggested by ros distro install?

[OscarDeGar]

Yes, thanks. Just did this and now I have a new error. It would seem that the python module future cannot be found however it is definitely install and up to date. See error below:

Try installing the "future" python package:

python -m pip install -U future

@OscarDeGar have you done rosdep stage?

@aa-calvo i'd suggest not to use pip. Usually it's preferable to use package from distro. E.g. apt install python3-future.

I am updating for @OscarDeGar I am working on this project with them. We managed a successful build of the environment by simply uninstalling all packages and repositories and starting over. At that point, there was a permissions error when running mavros but this was solved by elevating the read write privileges of the usb/serial interface.

Thank you for your help!

@jerWenger if you on Debian or Ubuntu simply add a user to dialout group. Look at ls -la /dev/tty{USB,ACM}*
