EDIT: Replaced vline~ with line~ objects, now patch compiles.
Please delete this post. Issue solved.
Original text below.
I get more compiler errors with a different patch to compile.
“/tmp/owl-build-tmtXxS/Source/HvMessage.c:17:23: fatal error: HvMessage.h: No such file or directory
compilation terminated.
make[1]: *** [/tmp/owl-build-tmtXxS/HvMessage.o] Error 1
make: *** [patch] Error 2
ERROR: Patch build failed.”
Is that my mistake?
