Problem with building the android export templates

I’ve tried to compile the library to use AdMob in my android game, but scons says that included file alloca.h is missing and stops the process. I’ve read the manual and installed all necessary tools, but the error is still here. Does anybody know how to fix that?

c:\godot>scons platform=android target=release

your ndk version?
try with latest ndk.

I’ve already updated NDK to the latest version. Actually those .h files scons can’t find are in the NDK folder, but for some reason scons can’t reach them.

So the problem really was with the NDK. Google changed the header folder in later versions of NDK!
So for anyone building the android export templates: USE NDK 13b, otherwise scons never find the headers!

Compiling using the Android NDK r16b with the latest Android SDK on Linux works for me.

What’s your version of Godot?
