Debian/Bookworm builds linking to two libFLAC versions

[jman-schief]

hey @midwan I noticed that the Debian/bookworm package links to two different FLAC libraries (1.4.x and 1.5.x):

$ ldd `which amiberry` | grep flac
	libFLAC.so.12 => /lib/x86_64-linux-gnu/libFLAC.so.12 (0x00007fe9e94d2000)
	libFLAC.so.14 => /lib/x86_64-linux-gnu/libFLAC.so.14 (0x00007fe9e7bf8000)

Now I'm curious: what is the reason for that?

Thanks!

Not sure, that's probably some weird side effect (maybe from the cross-compiler in the Docker container?). We definitely don't need both.

Bookworm doesn't contain libflac14 , that's only part of trixie/sid -- just tested on my Bookworm install, only links against libflac12.

Interesting. I opened this question specifically because I had removed libFLAC 1.4.x from my debian/trixie and Amiberry didn't start anymore.

I have installed Amiberry 7.0.5 (Bookworm package from the github release) and libflac 1.5.0

$ dpkg -l | grep "amiberry\|libflac"
ii  amiberry                              7.0.5                                  amd64        Optimized Amiga emulator for various platforms
ii  libflac14:amd64                       1.5.0+ds-2                             amd64        Free Lossless Audio Codec - runtime C library

and Amiberry does not start:

$ ldd `which amiberry` | grep "not found"
	libFLAC.so.12 => not found
$ amiberry --version
amiberry: error while loading shared libraries: libFLAC.so.12: cannot open shared object file: No such file or directory

Could be something with how Debian handles dynamic linking but can't say more. Maybe something to keep in mind when Trixie is promoted to stable (hard freeze is in May 2025, according to their release page)

This must be a trixie-specific thing. If I run the same thing here on Debian12, I only see it using libFLAC.so.12 => /lib/x86_64-linux-gnu/libFLAC.so.12 (0x00007f11d7073000).

Keep in mind the pre-compiled packages are only available for currently supported Debian versions, i.e. not Trixie yet.
