homography_rectifier_p->run(input_left_view, 0, boost::gil::view(rectified_left_view));

Note that AbstractStereoMatcher::input_image_view_t and AbstractVideoInput::input_image_t are different types.  The former is an any_image_view of const data, while the latter is an rgb8_image_t.

You can edit the message down to this:
StixelWorldApplication.cpp:296
error: ‘const class boost::gil::any_image_view</*unintelligible template gobbledygook*/>’ has no member named ‘pixels’

Which is true.  It looks like you're passing input_left_view, of any_image_view type, into run, which expects rgb8c_view_t.  Perhaps you need to use rectified_left_view (which isn't really a view) in conjunction with gil::view() (which will retrieve a view from the image).
 
I hope somebody can help me with that. As I said, I'm new on using Boost Generic Image Library and it is driving me crazy.

I can sympathize -- it's pretty easy to do basic things with GIL, and GIL allows you to do very complex things elegantly, but there can be a steep learning curve in between.


HTH,
