Error compiling px4_ros_com

ROS / MAVROS / MicroDDS
1

Hello together,

I’m now trying to install the px4_ros_com for few days but get stuck every time at the same point.
I’m able to compile px4_msgs but get the following error on px4_ros_com:

Failed   <<< px4_ros_com	[ Exited with code 2 ]

Summary: 1 package finished [12min 5s]
  1 package failed: px4_ros_com
  1 package had stderr output: px4_ros_com

I followed this guides and only want to install the ros2 part:

So I have installed:

  • fastrtps 1.8.2
  • fastrtpsgen 1.0.4
  • ros2 Dashing
  • px4 firmware latest
  • java-1.8.0-openjdk-amd64 AND java-1.11.0-openjdk-amd64 (tried both using update-java-alternatives)

I also tried to delete all that stuff and start from beginning. Deleted also under /usr/local and made sure with find that noting is left.

I saw that at the cmake command for fastrtps 1.8.2, as in the docs, it says:
cmake -DTHIRDPARTY=ON -DSECURITY=ON …
…
– Configuring Fast RTPS
– Version: 1.8.4

I’m not seeing what I’m doing wrong, any advises?

I saw related posts here, but nothing of them helped for me.

Ok, my fault, shame on me. I checked again /usr/lib and there were some older fastrtps libs as mentioned in another thread.
