Supposing you followed the instructions from http://libcinder.org/docs/welcome/GitSetup.html ... According to the site
"Cinder is free, open-source and available for Mac OS X, iOS and Windows."
So no ubuntu is supported out of the box.
When I look at the source it has some very deep dependencies to Windows and Mac internals, such as:
#if defined( CINDER_MAC )
#include "cinder/cocoa/CinderCocoa.h"
#import <Cocoa/Cocoa.h>
#import <AppKit/NSPasteboard.h>
#import <AppKit/NSImage.h>
#elif defined( CINDER_COCOA_TOUCH )
#include "cinder/cocoa/CinderCocoa.h"
#include "cinder/cocoa/CinderCocoaTouch.h"
#import <UIKit/UIPasteboard.h>
#elif defined( CINDER_MSW )
#include <windows.h>
#include "cinder/msw/CinderMsw.h"
#include "cinder/msw/CinderMswGdiPlus.h"
#include "cinder/Utilities.h"
#include "cinder/ip/Fill.h"
#include "cinder/ip/Blend.h"
#include <set>
#endif
so no Linux branch. However you could get "in touch" with cinder developers, ask them if they plan to provide Linux support ... Maybe volunteer yourself for it?
