Able to compile native code from apdfviewer?

I wonder if anyone else had problems running the ./ndk-build on apdfviewer?

I've everything working and set.. but i get errors for missing files (SkCanvas.h, SkPaint.h) .. and others related to 'LOGE'..? (i get those on cygwin console)

Can't figure out what am I missing... well, besides those missing files... but i 开发者_如何学运维"don't buy" that the developer has forgotten... I think I'm missing some import...

Please help...

Thanks!!

SkCanvas.h is part of skia, 2D Graphics Library. it's one of the build dependences.
