Building native samples

So I was able to run all samples exept ones using ndk.

I get this in console `

**** Build of configuration Default for project OpenCV Tutorial 3 - Add Native OpenCV ****

D:\pbIxtex\android-ndk-r7c-windows\android-ndk-r7c\ndk-build.cmd 
Install        : libnative_sample.so => libs/armeabi-v7a/libnative_sample.so


**** Build Finished ****

and this is the logcat

if i try ndk-build.cmd -B it goes like this

but the error is the same. I've tried CDT 8.1.0 and 8.0.2 and ndk r8b and r7c.

I've downloaded the samples from google play and they worked. Any suggestions?
