seems so.

Apple is issuing warning on first start of every 32-bit application that they'd be unsupported on 10.14.

mvm breaks with

MathPlugin.c deps/FloatMathPlugin.d
make[1]: *** No rule to make target `../../platforms/Cross/plugins/FloatMathPlugin/fdlibm/e_acos.c', needed by `build/FloatMathPlugin/acos.o'.  Stop.
make: *** [build/vm/FloatMathPlugin.lib] Error 2

but this looks actually unrelated…

My uneducated guess is that the entitlement makes no difference…

When I got to the point of two Linux headers both saying they should be included before the other, I stopped. The support in build.linux64ARMv8/gdbarm64 did seem to be as expected, including conf.COG and makeeem.
