Using Xojo2019R1.1 in Mojave. Running the app in the IDE gives no errors, nor does running a codesigned build. But when I add hardening to the build step, when the app is run I get an error when I try to open a window with a listbox: Could not load objc_allocateClassPair from libobjc.dylib. The error occurs in the XScrollView.Constructor.
An absolute or relative path to the Mach-O executable. In the case of system libraries, it should be absolute “/usr/lib/libobjc.dylib”, for a bundled executable it should be relative, based upon the main executable.
