Issues building from source

[TotalSpaceshipguy]

Hi @mincequi

I've managed to fix my build issue :) From what I can see, the thirdparty/qtzeroprops/thirdparty/QtZeroConf/CMakeLists.txt file in your master branch doesn't include the avahi-common library

I was able to fix the build by changing line 34 of that file from
target_link_libraries(QtZeroConf PRIVATE avahi-client)
to
target_link_libraries(QtZeroConf PRIVATE avahi-client avahi-common)

The current master of QtZeroConf at https://github.com/jbagg/QtZeroConf/blob/master/CMakeLists.txt seems to be a later one than your fork, and that version does also include a reference to avahi-common

I'm not sure why your build works. Maybe you have different source locally that hasn't been added to the github master yet, or your local setup is using a more up to date version of the QtZeroConf project, but I could not get the build to work by cloning the source into a new folder.

I'd love to do a pull request, but wouldn't know where to start lol - I haven't done any development for over 10 years !

Anyway, hope this helps someone else. An official amd64 release of the 0.8.1 deb would be handy as I couldn't see one, which lead me down this rabbit hole, but then I wouldn't have learnt anything ;)

Cheers

This looks like an incompatible version of libavahi. Did you try
sudo apt update && sudo apt upgrade
?

I happen to have a fresh installation of debian bullseye on AMD64 and everything works perfect here...

Hi

Thanks for the quick response :)
Yes, this was a fresh bullseye install and everything is up to date..These are the versions I have

So I have package v3.5.4 which is based on the avahi 0.8 source. This looks correct according to the file in the debian package list - https://packages.debian.org/bullseye/amd64/libavahi-common3/filelist

I do have another debian and ubuntu, install and they both have the same file version and sizes as the build environment

The build environment is actually a debian bullseye lxc container running on ubuntu 22.04 - maybe that's upsetting things ? I'll spin up a fresh virtualbox debian VM and try again

[TotalSpaceshipguy]

OK. I've created a brand new debian vm using the latest 11-6 netinst ISO
Ran an apt update and apt upgrade.. Installed all the listed dependencies and tried to build the source again.

I still get the same build error unfortunately :(

Hi @TotalSpaceshipguy

great to hear, that you had been able to fix that :)

Thanks for your input. I will update my refs to the most recent QtZeroConf.

Ok, just discovered that i only have armhf builds since this is my main target. However, you are absolutely right. Providing binaries for amd64 would ease up things...

...when i find the time, this project needs some cleaning anyway. ;)

@TotalSpaceshipguy thank for your tip about line 34 of thirdparty/qtzeroprops/thirdparty/QtZeroConf/CMakeLists.txt.

hey guys, cornrowd is conflicting with pulseaudio:

$ sudo apt install ./cornrowd_0.8.1_arm64.deb 
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Note, selecting 'cornrowd' instead of './cornrowd_0.8.1_arm64.deb'
The following packages were automatically installed and are no longer required:
  libltdl7 libpulsedsp libspeexdsp1 libtdb1 libwebrtc-audio-processing1 pulseaudio-utils
Use 'sudo apt autoremove' to remove them.
The following packages will be REMOVED:
  pulseaudio
The following NEW packages will be installed:
  cornrowd

do you know why?

[mincequi]

Hey @carnei-ro,
yes, this is intended. cornrowd aims to be a "bare-metal" bluetooth daemon for embedded devices. So, I do not support output via pulseaudio since pulse is very hardware hungry and supports bluetooth itself.
However, I often thought about to change that, but I ran completely out of time...
