Hi @carlstand , Were you able to build fastdds successfully for QNX SDP 7.1? If yes , can you please provide the steps and the toolchain file to build it? Actually I'm getting foonathan_memory issue. I'm attaching the error file for the reference. Thanks. |

@carlstand and @aniketshukla619, Me too trying to cross compile fast DDS in QNX platform but facing multiple issues. Could you provide me the qnx toolchain and steps? I'm pretty new to these things. Any help would be appreciated. |

QNX has official documentation on how to build ROS 2 for QNX here. The build process includes building Fast DDS. |

I am going to move this issue to the Unofficial support discussion forum. QNX is not an officially supported platform. According to the CONTRIBUTING guidelines, the issues related with non-officially supported platforms should be opened in this forum. |

when i run the example code of HellowroldExample Shared memory, it gives following errors on QNX7.1 system
i've check the issue #1606, but seems it still happened on QNX 7.1

System information
Additional context
the error log above happens when i restart the QNX, if i rerun the program, the first error e.g. "[RTPS_TRANSPORT_SHM Error] Failed to create segment fca0182b6b6d5908: File exists -> Function compute_per_allocation_extra_size" disappeared, but other errors remain
Thanks!
