CMake Error at Firmware/CMakeLists.txt

[zshn25]

I followed the instructions from https://pixhawk.org/dev/ros/sitl

I created and configured the workspace manually. Everything went well untill the last step.

When I run catkin_make, it gave the following error messages

CMake Error at Firmware/CMakeLists.txt:158 (include):
  include could not find load file:

    configs/nuttx_px4fmu-v2_default


CMake Error at Firmware/CMakeLists.txt:170 (message):

I have the same issue, pls help me

Can you try the updated documentation at dev.px4.io ? Do you specifically want to compile the firmware for ros, or just want a general sitl setup(provided in the updated doc on the link above) ?

[zshn25]

I already installed the toolchain from dev.px4.io. I want to compile the Firmware for ROS which includes SITL too.

I am not sure, but I guess the ROS compilation has some issues right now, you could go to previous commit master before the CMake branch was merged in.

Same issue here, anyone knows what changes introduced this recently ?

It still works. The ros build is tested on every commit. Try "make ros"

The basic problem I'm seeing with the ROS build (that gets run when catkin_make is called) is that Firmware/CMakeLists.txt assumes that CMAKE_SOURCE_DIR is the Firmware directory, but in the case of catkin_make, that isn't the case.

In a catkin workspaces, you typically have:

workspace_root_folder/
    src/
       /Firmware
       /Some_other_ROS_repo
       ....

Catkin seems to set CMAKE_SOURCE_DIR to workspace_root_folder/src/
Changing CMAKE_SOURCE_DIR to CMAKE_CURRENT_SOURCE_DIR gets me a bit further, but then it fails with:

CMake Error: File /home/jbinney/ws/px4/src/cmake/posix/apps.h_in does not exist.

I wasn't too clear in the previous comment; I was referring to chaging line https://github.com/PX4/Firmware/blob/b3bb8adbc5d3498bb95865820ec7a62bbf14c28e/CMakeLists.txt#L156 to replace CMAKE_SOURCE_DIR with CMAKE_CURRENT_SOURCE_DIR

[wkyoun]

Try this

catkin_make --cmake-args -DCONFIG=ros_sitl_simple

instead of catkin_make

[brandonr49]

Has this been fixed?
I just had the same error zshn25 posted.

[brandonr49]

Nevermind. This was my mistake.

We changed the way how things work, so closing this.
