Libkdegames in Mojave (was Re: Jigsaw puzzles)

Hi Lenore,

Can you just try something for me on your Mojave system?

In a Terminal window type the command:

    ll /System/Library/Frameworks/OpenAL.framework/Versions

The command is said as “ell ell”, short for “long list”. On my system (High Sierra) I get output:

    drwxr-xr-x  8 root  wheel  256  5 Apr 18:50 A/
    lrwxr-xr-x  1 root  wheel    1 19 Nov  2017 Current@ -> A

My guess is that, on Mojave, there will be an extra line, listing directory B/, and Current will point to B.

Please also try the command:

    ls /System/Library/Frameworks/OpenAL.framework/Versions/Current/Headers

I get output:

    MacOSX_OALExtensions.h  al.h
    OpenAL.h                alc.h

meaning that the file “al.h” is there to be found.

What output do you get? My guess is that “al.h” will not be there on your Mojave system.

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.
