Please post a recipe to reproduce those complaints:
the .spec file (or URL), other context for building, etc.

Sorry, I was hoping it was obvious. I'm only building in locally right now so I have uploaded it here:
https://hobbes1069.fedorapeople.org/emqx-nanomq.spec

 
When I build according to README.md at https://github.com/emqx/nanomq
"Building From Source", without Ninja:

    git clone https://github.com/emqx/nanomq.git ; cd nanomq
    git submodule update --init --recursive
    mkdir build && cd build
    cmake ..
    make

then I see no complaints from /usr/bin/ld.

Yes, it seems to be an issue when trying to enforce all of Fedora's build flags.

Full build log here:
https://hobbes1069.fedorapeople.org/build.log

 
The software package itself is low quality.  gcc complains dozens of
serious errors such as:
    nng/src/nng.c:2269:1: warning: control reaches end of non-void function [-Wreturn-type]
    nng/src/sp/protocol/mqtt/nmq_mqtt.c:271:51: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
    nng/src/supplemental/mqtt/mqtt_qos_db.c:620:13: warning: unused variable ‘rv’ [-Wunused-variable]
      620 |         int rv = sqlite3_exec(db, "COMMIT;", 0, 0, 0);

Thanks. I'll make sure that makes it upstream.

Richard
