What instructions are you following? Where does it fail?

Hello, JulianOes:
I want to receive uorb topic message with ROS2 and I follow the instruction “https://dev.px4.io/master/en/middleware/micrortps.html”.
I installed the ROS2 ardent and Fast RTPS, but the error appear after the command “make px4_sitl_rtps” under Firmware folder.

this is the error list:

But what steps have you done to install all prerequisites? And did they all succeed?

FYI @TSC21 maybe you can help here.

it seems that the prerequisites needed is ros1 kinetic, ros2 ardent and Fast RTPS.
first I install ros1 kinetic with “sudo apt install ros-kinetic-desktop”,
then ros2 ardent was installed with “sudo apt install ros-ardent-desktop”,
after that I install Fast RTPS under the instruction below:

$ git clone https://github.com/eProsima/Fast-RTPS
$ mkdir Fast-RTPS/build && cd Fast-RTPS/build
$ cmake -DTHIRDPARTY=ON -DBUILD_JAVA=ON …
$ make
$ sudo make install

the installation process is OK

I tried to reproduce this and I can’t even install Fast-RTPS successfully, so I’ve made an issue: https://github.com/PX4/Firmware/issues/12773

Thank you for your help!
may be this problem is caused by FAST-RTPS installation.
