compiles fine on ubuntu linux using gcc 4.4.1.
It should not. Are you sure this is exactly the same code that you
actually compiled? If it really is the same, then you must be invoking
the compiler with some wrong options.
These are the options that I use:
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -w -s -lX11 -Dcimg_use_xshm -lXext -Dcimg_use_xrandr
-lXrandr -O3 -fpermissive -march=nocona -m64 -ffast-math -funroll-loops -finline-functions")
There are plenty of other stuff that is not caught using gcc. As an example I have this:
template <typename A, typename J>
class Producer {
public:
typedef J JobType;
const unsigned int Dimension = JobType::Dimension;
...
....
which compiles fine when using gcc. But in VS I need to a the static keyword to make it compile:
const static unsigned int Dimension = JobType::Dimension;
