Hi Pau, The Android Necessitas Qt project moved from MinGW to MinGW-w64 for our A4 release.
As we also build our own version of the Android NDK for Necessitas, we used (improved and merged back into) their mingw-w64 build script also build our cross MinGW compilers: https://android.googlesource.com/platform/ndk/+/5d6dd385bd9814e8da832c70a598a729b9172585/build/tools/build-mingw64-toolchain.sh For the released Windows version I used ruben's 4.7.0 GCC (the cross compile did work fine for Qt and Qt Creator actually, but we never got the packaging side of things finished) We've run into just one bug so far in the Qt Creator we released with it (and it's unlikely the compiler's fault).
