I'm glad to see that this project is moving on and especially that
it's using Qt :) However, I get a compile error with revision 2:

g++ -c -m64 -pipe -O2 -fmessage-length=0 -O2 -Wall -D_FORTIFY_SOURCE=2
-fstack-protector -funwind-tables -fasynchronous-unwind-tables -g

-I/usr/include -I. -I/usr/X11R6/include -I. -o Camera.o Camera.cpp
Camera.cpp: In member function ‘void Camera::print()’:
Camera.cpp:76: error: ‘stderr’ was not declared in this scope
Camera.cpp:76: error: ‘fprintf’ was not declared in this scope
make: *** [Camera.o] Error 1

I believe it just needs a '#include <cstdio>' at the top of Camera.cpp.
