Hello. I am trying to build obs from ports and I was facing the same issue related here:

Thread 'Unable to build OBS because of old github issue'

Since last year if you try to build multimedia/obs-studio, it throws a link to this Github issue and says obs-studio is marked as broken. It seems like this was fixed in October yet we still can't build it - the tag is for 27.2.3 and that version is currently in quarterly ports. Anyone know why?

I also commented the line PULSEAUDIO_BROKEN_OFF and the build went on. But differently from the deleted user on the thread I linked, I am facing the following issue:

Code:

Pulseaudio is disabled in config, I also didnt selected it for any dependecies while building (I guess), also, reading the port makefile, I tried to build with -DDISABLE_PULSEAUDIO=true and -DENABLE_PULSEAUDIO=false but I got the same output.

I dont really want to install pulseaudio, but also, I dont know how to avoid that. Could you guys give me some ideas?
At make config of obs I am selecting only pipeware and sndio.
 
Since the bug was closed and not reopened, the issue still exists: you have to have pulseaudio when building without pulseaudio (that is why the option is marked as broken when turned off).
One way to build it without pulseaudio would be to use a chroot, and install pulseaudio in it before doing the build.
Then you can install the generated packages.

And of course there is no guarantee that you could run it afterwards, since it is linking to pulseaudio, maybe you could fix it by writing a stub library that fake pulseaudio.
 
After your post I've readed the older post again carefully.

This dont really match what is being said at the post and the issue. I guess the OP off the old post had pulse instaled and was not using it maybe...

I find it too much... Even if this is simple. I thank you anyway!

could be an port misconfiguration?

I will try checkout obs repo and built it for my user to see what happens.

Yep, when buildind directly:


Code: 
cmake -S . -B /tmp -G Ninja \
    -DENABLE_RELOCATABLE=ON \
    -DENABLE_PORTABLE_CONFIG=ON \
    -DENABLE_PIPEWIRE=ON \
    -DENABLE_PULSEAUDIO=OFF &> /tmp/obs.log

there is a way to the port prints the cmake flags like when building directly? My guess is even if we disable pulseaudio, it will keeps goin turned on.
 
I've ended compiling obs myself and also opened an issue/PR at their repo. It ended with Yuri updating the port and some other questions about BSD dependencies over OBS. Now everything just works fine and it should build fine at ports.
I am marking this as solved.
