I’ve tried compiling the project that you provided on a couple different macs and Binary builds but I’m getting the same result with the .dylib errors. If I try compiling the project with a source built engine however, I receive errors related to the source for your plugin, such as undeclared identifiers and missing constructors. Could you try downloading 4.9, 4.10, or 4.11 Preview from Github and see if you get these same errors? If so, it may be able to point you in the right direction.
