I get 'vec2' has not been declared among other errors.

I get

Code:
This file requires compiler and library support for the ISO C++ 2011 standard. This support is currently experimental, and must be enabled with the -std=c++11 or -std=gnu++11 compiler options.


even when im including

Code:
LOCAL_CFLAGS := -std=c++11


on my android.mk


this is the output of the compiler
Code:

[armeabi] Install        : libSDL2_image.so => libs/armeabi/libSDL2_image.so

Shouldn't you be using LOCAL_CPPFLAGS, since you're using a C++ Compiler?

And are you sure your compiler even supports c++11? gcc 4.7 or later or something, if I recall correctly

Yeah I was running with 4.8 and 4.9 but that was not the issue, I solved it by using

Code:
APP_STL := c++_static


Instead of

Code:
#APP_STL := gnustl_shared
