Thank you for your response, I managed to get a simple 
no-druntime-no-phobos app running with a function written in D.

Now I am trying to create a wrapper around a library that uses 
the runtime and phobos extensively, and even though the 
`libphobos2-ldc.a` and `libdruntime-ldc.a` files (created by 
`android-setup.d`) have been linked into the .a file that 
resulted from using
> dub build --compiler=ldc2 --arch=armv7a-none-linux-android
on my library, I still get linker errors telling me that symbols 
from phobos and druntime are undefined. (At least, I think I 
linked them in properly, because the size is approximately equal 
to the sizes of `libphobos2-ldc.a` and `libdruntime-ldc.a` added 
up.) Do you have any idea what could be wrong with my setup?

I am on windows and am using Android Studio v3.6.1, NDK 
21.0.6113669 and the newest version of LDC2.

Thanks in advance.
