Thanks! The Termux docs did mention that dlopen was "different": > Symbol visibility when opening shared libraries using dlopen() works differently. On a normal linker, when an executable linking against a shared library libA dlopen():s another shared library libB, the symbols of libA are exposed to libB without libB needing to link against libA explicitly. This does not work with the Android linker, which can break plug-in systems where the main executable dlopen():s a plug-in which does not explicitly link against some shared libraries already linked to by the executable. See the relevant NDK issue <https://github.com/android-ndk/ndk/issues/201> for more information.
I have no qualms about digging around in the sources. I was sort of hoping I'd have to do that. Anyway, removing the noted vesdigital code just caused a failure in ffi/unsafe, specifically in the body of get-ffi-obj*. I'll start messing around with linker flags tomorrow.
