Why not https://lib.openmpt.org/libopenmpt/2020/04/14/release-libopenmpt-modplug-0.8.9.0-openmpt1/ ?

That produces libopenmpt_modplug not libmodplug. All the other distributions have libmodplug, I can vaguely remember it in openSUSE as well, was most probably deleted in favor of the one provided by libopenmpt.

I have checked the ABIs.

First, libmodplug-0.9.8's libmodplug.so.1 against libopenmpt-0.4.12's libmodplug.so.1:

» abidiff $a/libmodplug.so.1 $b/libmodplug.so.1
[...]
3 Removed function symbols not referenced by debug info:

  _ZN10CSoundFile13InitializeDSPEb
  _ZN10CSoundFile14ProcessMonoDSPEi
  _ZN10CSoundFile16ProcessStereoDSPEi

Well that's a great start :-/ so libopenmpt was binary incompatible all along. But no one noticed, so openmpt has that going for it.

Now, libopenmpt-0.4.12's libmodplug.so.1 against libopenmpt-modplug-0.8.9.0's libopenmpt_modplug.so.1:

» abidiff $b/libmodplug.so.1 $c/libopenmpt_modplug.so.1
ELF SONAME changed
Functions changes summary: 0 Removed, 0 Changed, 0 Added function
Variables changes summary: 0 Removed, 0 Changed, 0 Added variable

SONAME changed from 'libmodplug.so.1' to 'libopenmpt_modplug.so.1'

So no ABI change there. This suggests that if libopenmpt-modplug was built with the right SONAME, we would have the same situation as a few days ago. Sounds like a plan?

I was looking for a quick clean solution I also dislike long names, somebody else is welcome to create libopenmpt_modplug1 and provide libmodplug1 Have a look at the git fork https://github.com/Konstanty/libmodplug, it is a currently active fork of the original libmodplug

The libopenmpt_modplug also has this option: --enable-libmodplug Enable libmodplug replacement library based on libopenmpt. WARNING: This will replace your current libmodplug installation. CAUTION: The emulation of the libmodplug interface is not complete as libmodplug exposes lots of internal implementation details. If any of those is used by an application, the emulation via libopenmpt will fail and/or crash.

I was stupid not to search for libmodplug in openSUSE it's last days were in Leap:42.3:Update using the github version. modplug is very old and it's only use is for converting music that was made in the 90s but it's nice to have it around. It still builds with gcc10

Well even for 90s music, one can use openmpt or xmp or something :-)
