Android question (for porting EQL5 to that platform)

Hi all, I'm currently trying to port EQL5 to the android platform. There is a big show-stopper to this: - building ECL for android only works with NDK r9 (which is really old already) - building EQL5 for android only works with NDK r15 (for Qt 5.9; but Qt5 requires a recent NDK anyway) Since I need to link the both together, I have an incompatibility issue during the final linker step. Now, the only solution I see (so far) would be this: making ECL work with latest NDK r15. Did anybody already give it a try? Is it feasible at all? (We need to look at what we would be gaining: EQL5 on android, using QML and Lisp, just would be too nice to have!!) Thanks, Paul
