error compiling in android studio

[Smashman4]

Decided to take a whack at porting Mighty Mike to Android, but fist I decided to see how pomme would work in android.
I get this error when I try to compile just the libraries or compiling Mighty Mike using a template from the SDL site
android-project/app/jni/src/Sound/cmixer.h:120:19: error: implicit instantiation of undefined template 'std::span<char, 4294967295>'

Let need know if you need more details.
