That’s odd, I was expecting a B version for whatever Apple OSX is doing now in OpenAL.framework in Mojave, with the A version left as it was.

Not so, I was expecting there to be at least one header, such as OpenAL.h, which incorporates al.h and alc.h (both are referenced by libkdegames code).

Instead we have no headers at all, not even a Headers directory. Weird…

I believe Apple OSX uses OpenAL for its own sounds, which I daresay are still working on Mojave and Catalina, so Apple must have some new way of linking the OpenAL package into apps and other programs.

I will see if I can escalate this problem via Ticket #57294 or the MacPorts Developers’ list, but I have been out of touch with both for a long time.

Cheers, Ian W.

However I will see if I can recall how the KDE Games builds work and if I can get up-to-date with MacPorts, selfupdates and upgrades. I must confess I am hopelessly behind with MacPorts maintenance (hell, I’m 82 now), but I did have some experience introducing the use of OpenAL into KDE Games several years ago. I won’t be moving to Mojave any time soon, though.
