find_package error

[emirkarayilan]

sir, i am getting an error at colcon build step. Can anyone help?;
CMake Error at CMakeLists.txt:13 (find_package):
By not providing "Findpx4_msgs.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "px4_msgs",
but CMake did not find one.

Could not find a package configuration file provided by "px4_msgs" with any
of the following names:

px4_msgsConfig.cmake
px4_msgs-config.cmake

Add the installation prefix of "px4_msgs" to CMAKE_PREFIX_PATH or set
"px4_msgs_DIR" to a directory containing one of the above files. If
"px4_msgs" provides a separate development package or SDK, be sure it has
been installed.
(i am a beginner for ros2 and i open for all advices)
thanks!

Hi, I think you need to clone and build "px4_msgs" first in your workspace

git clone https://github.com/PX4/px4_msgs.git

i am still getting an error. Maybe i couldnt build "px4_msgs" package. Can you help me about setup?

[ahmad12hamdan99]

In this case, I think you should try to clean the whole workspace and rebuild

cd ~/ros2_ws
rm -r build install log

Then try to build

colcon build --packages-select px4_msgs

i did what you say but i am still getting this error.

It seems like you have a problem with setuptools
please try this

pip3 install --upgrade setuptools

and then redo my previous comment
Good luck!

px4_msgs is done but for now px4_swarm_controller created a problem
