build.sh Issue

[sabdi1]

Hello.

I have a previous version of the Crazyswarm in another location that I've made modifications to and runs fine.

I've cloned the current repo into a new location, and attempted to run the build.sh script and run into a CMake issue:

-- +++ processing catkin package: 'crazyswarm'
-- ==> add_subdirectory(crazyswarm)

Invoking "cmake" failed

Any ideas on why I'd be running into this issue?

Sounds like a old cmake version. Which OS and cmake are you using? We run continuous integration tests on Ubuntu 20.04 with ROS noetic.

[sabdi1]

Ubuntu 18, CMake 3.10.2, python 2.7.17

[whoenig]

target_link_directories was added in cmake 3.13. You could upgrade cmake, or try to change the CMakeLists file to only use older functions (PRs welcome).

Updating CMake allowed me to finish the install.
When I run the associated pytest, the only one that fails is the test_videoOutput.py.
However, when I try to run python chooser.py i get:

WARNING: Could not find STM32 firmware (/home/sabdi/crazyswarm_ws/crazyswarm/ros_ws/src/crazyswarm/scripts/../../../../crazyflie-firmware/cf2.bin).

[rospack] Error: package 'crazyflie_tools' not found

[rosrun] Couldn't find executable named reboot below

Which are not errors I've seen before.

I believe it was having trouble finding 'crazyflie_tools' because I wasn't sourcing properly. The issues above remain and once I launch python chooser.py with these errors and try to reboot the CF, I get a timeout error. The terminal shows:
