Hi, I clone the Apollo project(v6.0) and build the cyber_rt module with cmake,but I found the example "common_component_example" run failed. I dbg it and found that when the writer want to publish it's channel change msg,it can not send the fully message:

   bool Manager::Publish(const ChangeMsg& msg) {...
  apollo::cyber::transport::UnderlayMessage m;
    RETURN_VAL_IF(!message::SerializeToString(msg, &m.data()), false);
     return publisher_->write(reinterpret_cast<void*>(&m));}

Here the msg will be serialized by protobuf to data member of undelaymessage ,but the serialized data contails "\0" and the fast-rtps(or fast-dds) may be not support send "\0" message data, here is the evidence: [https://github.com/eProsima/Fast-DDS/issues/2689#issuecomment-1132705252] [https://github.com/eProsima/Fast-DDS/issues/2786] So, How to solve this problem?Does I missed anything such as any correct config?

there're two question to be check

1. does fast-rtps support send \0
2. cmake support for cyber or apollo

[minhanghuang]

fast-rtps need patch

[daohu527]

which patch? you mean docker/build/installers/FastRTPS_1.5.0.patch?

fast-rtps need patch

I used the patch tool, but this situation still occurs, but my platform is risc-v. Do I need to modify the patch file? Looking forward to your reply, thank you
