Building on macOS does not use libraries installed by package managers about squeezelite HOT 5 OPEN

This is on purpose as I build all the decoders and support libraries as part of the my macos squeezelite builds.
Adding the PATH(s) to these other package managers break my builds.

What about having extra Makefiles like Makefile.m1-pkgsrc and Makefile.m1-macports?

from squeezelite.

I don't know if this is the kind of thing ./configure would fix, but I was able to get squeezelite compiled on my M2 Mac today. The packages available on the website the OS said were all corrupted.

I don't know what the cleanest way of handling these things are or I'd make a pull request so I'm documenting them here because the binary works fine. I haven't written C code since the 90s.

Apple M2 Mac running Ventura

1. Comment out the -rt stuff because it's not Linux
2. Force PORTAUDIO because it was trying to use ALSA
3. add -I /opt/homebrew/include to CFLAGS and -L /opt/homebrew/lib to LDADD so it could find all the includes and lib.

Hope that helps!

Yes.

Not sure, what you mean here.

I guess you did not use the existing m1 Makefile. You can specify it like that: make -f Makefile.m1

3. add `-I /opt/homebrew/include`  to CFLAGS and `-L /opt/homebrew/lib` to LDADD so it could find all the includes and lib.

Yes, that is basically what you need to do. Tell the build system, where headers and libs are.

Corrupted packages from the Sourceforge site:

I tried using the Makefile.m1 and it looks like it was very hacked for someone's specific machine. I think the Opus stuff might just be a quirk in how Homebrew packages stuff so I wound up taking OPUS and ALAC out since it didn't seem worth fighting with right now to get a clean compile.

This is what I had to change:

Briefly:

1. The gnu99 stuff
2. Removed the sysroot stuff as it wasn't needed and just broke things
3. Took out DALAC and DOPUS because they were just causing headaches on my machine. I'm guessing I could fight to get the stuff in the right place to make it work because Homebrew didn't have it or do it. The ALAC stuff is over a decade old at this point.

tl;dr I think it would be cool to get the Sourceforge downloads to not be broken. Otherwise, the Makefile.m1 (and Makefile) needs a little love if people are going to use it without too much trouble. I think the package manager stuff could be handled more cleanly in variables than as hardcoded.

If we can get these sorted out so that most people are happy, I'm happy to submit a PR for the README which is currently not useful to anyone.
