I'm using NDK r18, SFML 2.5, Android API 24, Clang on MacOSX. STL=c++_shared.
And I made sure the STL value was the same across cmake and the generated makefiles.
I followed both the SFML official guide and a template found here on the forums. Both end with the same error. I'll show
the command line example from the official guide only:
Here is the output

Someone on IRC said it might be link order so I've tried every possible combination. And I know it has to be a specific order: dependent libraries first so graphics then window then audio/network then system. As you can see I have that too.
I tried static and it installed but crashed on startup. Reading the official android C++ docs, they mention
static is not suggested and use shared instead.
Help me get this to build and run right on android.
