Description:
When starting the GUI, I get this error:

mkvtoolnix-gui: symbol lookup error: /usr/lib/libmatroska.so.6: undefined symbol: _ZTIN7libebml10EbmlMasterE

and the program fails to start.

Additional info:
* package version(s)

mkvtoolnix-cli 34.0.0-1
mkvtoolnix-gui 34.0.0-1
libmatroska-1.5.1-1

Steps to reproduce:
Just run /usr/bin/mkvtoolnix-gui from the command line.

I've tried reinstalling extra/libmatroska but that did not fix it.

pacman -Qs libebml ?

MKVToolNix author here. It seems that the Arch package maintainers for libebml/libmatroska compiled those packages wrong, or in the wrong order or something like that. I can see your problem with the current Arch packages (libebml = 1.3.8-1, libmatroska = 1.5.1-1). I cannot even compile & link MKVToolNix from source against those two versions.

However, when I compile libebml 1.3.8 and libmatroska 1.5.1 from source, I can compile MKVToolNix against those self-compiled libraries, and the resulting mkvmerge works fine.

The solution should be to rebuild libebml 1.3.8 first, then rebuild libmatroska 1.5.1.

No, libmatroska is correctly compiled against libebml 1.3.8. Please attach the full output of 'LD_DEBUG=files mkvtoolnix-gui'

Using mkvmerge, not mkvtoolnix-gui; same issue.

and 'ldd /lib/libmatroska.so.6'?

It seems to happen in release mode only. This is rather bad, obviously — I'll open a bug for libEBML & libMatroska shortly. For the time being please either pull both library updates & revert to the previous versions or rebuild the current versions without -DCMAKE_BUILD_TYPE=Release. Thanks.

Not linked to libebml, it seems.

The problem is not due to building shared libraries. It happens with static versions, too; in that case when trying to link any of the MKVToolNix binaries.

This is the bug for libEBML tracking the problem: https://github.com/Matroska-Org/libebml/issues/50
Comment by Moritz Bunkus (mbunkus) - Monday, 27 May 2019, 14:00 GMT
New releases of both libraries have been made which should fix the issue.
Comment by Maxime Gauduin (Alucryd) - Monday, 27 May 2019, 14:34 GMT
New releases are up, fix confirmed!
