[SOLVED] [slackware-current regression] SDL2_mixer and SDL_mixer need rebuilding: fluidsynth broken

teeemcee · 09-07-2021, 12:38 AM

Hi all,

SDL_mixer (v1.2 and 2.0) are configured by default to runtime loading of libraries including fluidsynth, but they load a specific .so version:

Code:

> strings /usr/lib64/libSDL2_mixer-2.0.so.0 | grep '\.so'
libSDL2-2.0.so.0
libm.so.6
libc.so.6
libSDL2_mixer-2.0.so.0
libFLAC.so.8
libfluidsynth.so.1
libmodplug.so.1
libmpg123.so.0
libvorbisfile.so.3
libopusfile.so.0

From "libFLAC.so.8" on down these are strings passed to dlopen(). SDL_mixer 1.2 has similar dependencies.

fluidsynth is now at libfluidsynth.so.3, so MIDI playback with it doesn't work (silently fails at runtime, may or may not successfully fallback to its builtin Timidity fork).

Also, the SDL2_mixer-compat32-2.0.4-x86_64-4compat32 package (provided by Eric) can't be linked to because it's been linked to libmad, but no libmad-compat32 is provided:

Code:

/usr/bin/ld: warning: libmad.so.0, needed by /usr/lib64/gcc/x86_64-slackware-linux/10.3.0/../../../../lib/libSDL2_mixer.so, not found (try using -rpath or -rpath-link)
/usr/bin/ld: /usr/lib64/gcc/x86_64-slackware-linux/10.3.0/../../../../lib/libSDL2_mixer.so: undefined reference to `mad_stream_finish'
...etc.

This is strange, because SDL2_mixer defaults to using libmpg123 rather than libmad. (No libmpg123-compat32 either.) Note that SDL_mixer doesn't have an option to dlopen libmad.

MMMM

Code:

ldd  /usr/lib64/libSDL2_mixer-2.0.so.0
        linux-vdso.so.1 (0x00007fffb4b6c000)

seems you have a problem but slackware current is fine. take it up with Alien bob or rebuild the packages that link to them.
as far as stuff missing in multi-library whats new just look at ffmpeg-compat32.

Code:

ldd /usr/bin/fluidsynth  | grep missing

And most of all sometime Eric doesn't keep up I am sure you can use his build scripts.

lovemeslk · 09-07-2021, 03:06 AM

You may want to do like I do Just pull the compat32 from the latest's updates.

Code:

mkdir slackware64-compat32 && cd slackware64-compat32 && su -c "massconvert32.sh -u https://mirrors.kernel.org/slackware/slackware-current/slackware/"
su -c "upgradepkg --install-new *?/*.t?z"

As for anything you install from Eric's repo you have to rebuild or wait till he has time to catch up.

BTW, I got the impression that this forum is the preferred place to report issues with Slackware, considering that there's no obvious email address provided to report issues.

I'm sorry, I don't want to be rude, but you completely misread my post. SDL_mixer uses dlopen() to dynamically link these libraries, as your ldd output proves: all the libraries it uses for decoding audio files are missing!

And yes, I know it's a bit lazy to complain about Eric not having a complete set of compat32 packages, but he usually does such an amazing job that I only wanted to help improve it! I usually compile SDL_mixer myself because I sometimes patch it, and often want to use latest dev version. For example, there hasn't been an official release of SDL 1.2 or SDL_mixer 1.2 in 8 years, but there are many fixes in git.

so rebuild it I do not see an issue with it.

it shows them all there !
at anytime do you see the word missing.
scratch my head say have a great day.
You want a complete slackware studio

Quote:

Also, the SDL2_mixer-compat32-2.0.4-x86_64-4compat32 package

That would be fixed in that script I added. That's all Eric does he wrote the massconvert32.sh script just for this reason.
So you the user can stay up to date with current. Other wise he would be spending way to much time converting and syncing.
He gave you the tools when you installed multi-lib

Code:

mkdir slackware64-compat32 && cd slackware64-compat32 && su -c "massconvert32.sh -u https://mirrors.kernel.org/slackware/slackware-current/slackware/"
su -c "upgradepkg --install-new *?/*.t?z"

Oops, you're correct. I must have pasted the wrong thing from my shell history. Nonetheless, "libfluidsynth.so.1" is still the same.
And of course, SDL2_mixer.SlackBuild does enable libmad support; I shouldn't have been surprised earlier. (It's also a pity Slackware doesn't have libmodplug; mikmod (built into SDL_mixer) is inferior.)

Quote:

Yes, that's what I'm asking for : )
As said, because it runtime-links with dlopen() it fails at runtime; ldd can't show you anything about that.

wtg "teeemcee" seems I missed it. Thanks for being patient.

Code:

l/SDL2_mixer-2.0.4-x86_64-5.txz:  Rebuilt.
  Rebuilt to fix embedded shared library .so-versions used for dynamic loading.
 Thanks to teeemcee.

teeemcee · 09-08-2021, 11:22 AM

And thanks for trying to be helpful.
Guess I should report issues here afterall, then.
