Hi Daniel,
Have you mixed homebrew and macports? That’s not a good idea they say.
I’ve personally used only homebrew, and I haven’t had any issues installing software I’ve needed.
Openmotif needed Xquartz, setting the CFLAGS was all really needed, the libs were found automagically, but
setting -L/usr/X11/lib in LDFLAGS didn’t mess anything, and it looked more correct.
Yes, X11 is dying, but as I’m used to use motif on Linux, I just tried to build snd with motif on macOS, and it works
nicely.
Best regards
