Native Android Build Relies on CPP #1311

Open xloem opened 3 years ago

xloem commented 3 years ago

The newer android NDKS (I'm using 21.4.7075529) do not include a CPP binary. It's replaced by passing -E to CC (so, something like aarch64-linux-android21-clang -E).

Additionally the need to pass the correct compiler to ant via CC= should be added to the android documentation in the /www/ subfolder.

Fixes are welcome, please don't break builds on old NDKs.
