Error when building RCLCPP #8

Closed pablogs9 closed 4 years ago

pablogs9 commented 4 years ago

Hello, I have been following VxWorks 7 SDK for Raspberry Pi 4 instructions and this repo instructions in order to run some ROS2 demos on VxWorks 7 on a RPi 4.

I get the following error when building rclcpp:

--- stderr: rclcpp                                                                                                              
CMake Warning:
  Manually-specified variables were not used by the project:

Can I have some support with errors? Thank you so much!

Currently, I am facing the same issue for the RPI 3B+ SDK. As I successfully build the libraries before at the end of June using the Docker Build infrastructure, I was surprised by the fact that recently the docker build fails involving the ROS2 rclcpp package. I have tested the following versions with nealry the same outcome:

vxworks-ros2-build branch wrsdk RPI3 version Outcome
dashing-releaseSR640 1.4 rclcpp failed
SR0650 1.5 Make-Target fails because of missing rule
master 1.5 Fails as dummy.c is missing
master 1.4 rclcpp failed
dashing-release 1.5 fails to configure asio
dashing-release 1.4 rclcpp failed
dashing-release-python 1.4 rclcpp failed

Is there a supported set of fixed combinations of different versions? For further debugging purposes I attached trace as well.

Hello @sdoerr20, thanks for reporting it. It shall be possible to build an RPI3 image with ROS2 against the SR0640 SDK which is https://labs.windriver.com/downloads/wrsdk-vxworks7-raspberrypi3b-1.4.tar.bz2 Let me look into it.

Hello @pablogs9, thanks for reporting it. The RPI4 SDK for ROS2 is also the SR0640 one -https://labs.windriver.com/downloads/wrsdk-vxworks7-raspberrypi4b-1.0.tar.bz2. Will look into it as well.

This issue shall be fixed now with https://github.com/Wind-River/vxworks7-layer-for-ros2/commit/81197b31d35cc55fe1fe1c413cc50c68564036fe I have tested it on QEMU, please let me know if it works for you, that I can close it. I'll update a README saying that the build works with SR0640 SDKs at the moment.

Thanks @razr for this update. Closing the issue.
