Hi,

on my computer:
find /opt/android-*/ -name new
/opt/android-ndk/toolchains/llvm/prebuilt/linux-x86_64/lib64/clang/7.0.2/include/cuda_wrappers/new
/opt/android-ndk/sources/cxx-stl/system/include/new
/opt/android-ndk/sources/cxx-stl/llvm-libc++/include/new

In the ./qml_box2d-prefix/src/qml_box2d-build/Makefile file, do you have
"-isystem /opt/android-ndk/sources/cxx-stl/llvm-libc++/include" in you
CXXFLAGS?
