Just to clarify - in our case the issue cannot be related to OpenSSL as both working and broken configs are the same? |

@Tobias-Fischer Yes, looks that way, doesn't seem to be OpenSSL version issue at least. |

@traversaro Thanks, I'll diff that against mine and see if I can isolate my problem. |

@traversaro There aren't many differences in packages, and nothing that seems relevant 🤔 Yours (ST) |

My suspect is that one of us has something corrupting/interfering with the system/environment in some way. |

This documentation points at the need for Visual C++ Redistributable Packages for Visual Studio 2013 to supply via I tried installing that (Windows Installer) but no luck. Will try to restart and check again. EDIT: I restarted with no-luck and re-ran the Visual C++ 2013 Redistributable installer again:

Great debug! The issue then is that the run_exports for foonathan-memory should be stricter: https://github.com/conda-forge/foonathan-memory-feedstock/blob/47bf93075f75cc4645b5c77f9a26bb9b84697242/recipe/meta.yaml#L21 . This is because the library has a form of manual soversion by changing the library name: https://github.com/foonathan/memory/blob/f75c9fc761fde7fa0f6a829df08ea0041ebf1f10/src/CMakeLists.txt#L109 . |

conda-forge/foonathan-memory-feedstock#7 should fix the issue for future builds, but for past build we should pepare a repodata patch and submit a PR to https://github.com/conda-forge/conda-forge-repodata-patches-feedstock, something like conda-forge/conda-forge-repodata-patches-feedstock#286 . |

This is now working fine with the fresh builds, at least on Linux. However, see RoboStack/ros-noetic#30 |

Hi @danzimmerman, could you please let us know whether this is still an issue with the new builds in the robostack-staging channel? |
|
@Tobias-Fischer Sure, happy to. I just tried it with these channels: and But I can't find the desktop package. Do I need to wait a while for it to propagate? |
|
Sorry, still working on ros-humble-desktop on Windows. However, https://anaconda.org/robostack-staging/ros-humble-rosbag2-py is available which should be enough to test this particular issue? |

Seems to work fine here to import Didn't get a chance to actually open a bag file yet, which seemed to also give me some trouble. I'll try some other things later when I get a chance, but the basics seem to be working. |

Ok - let’s close here then, if you have rosbag troubles please open a separate issue. |

Issue
I installed ROS2 Humble on Windows today and had an issue locating the FastDDS RMW implementation.
To reproduce the error, it's sufficient to
import rosbag2_pyin Python. (EDIT: and, apparently, have theRMW_IMPLEMENTATIONenvironment variable set tormw_fastrtps_cpp, see final comments below)The error kills the Python interpreter as well ("Kernel has died" in Jupyter or a silent exit from a Python prompt)
I have two older installs where this does not seem to have been a problem.
On one of the older installs and this fresh install, there is a
rmw_fastrtps_cpp.dllin theC:\Users\<username>\mambaforge\envs\humble\Library\bin, but it seems like the fresh install can't find it (or maybe it is returning the wrong identifier?)On the broken machine, I tried installing Fast DDS with the Windows installer from the eProsima website, which does resolve the error (installs the required files and sets
FASTRTPSHOMEenvironment variable). However, I didn't recall needing to do this in the past on the other working machines, and the working machine I have access to right now doesn't have it explicitly installed.On the broken machine, the problem returns when I uninstall it.
