I went to nightlies to fetch the debug version of Ardour 6.9 and downloaded Ardour-6.9.0-dbg-x86_64.run. When installing I am warned that
WARNING: GCC4/5 libstdc++ ABI Mismatch
Ardour was compiled with gcc4, your system uses a newer version of the
standard c++ library. Plugins on your system may not load or plugin-UIs
may cause crashes.
I didn’t get this warning while dealing with any of the 6.8-versions, nor with the 6.9 from the official download. There were some packages updated recently, but I don’t know how to tell when this particular package was last updated.
Should I just proceed anyway, or are there better paths to follow?
Not sure if I’m looking in the right place, but “apt show gcc” returns
