#29196: boost-gil-numeric @1.0 (devel), gil examples which come with the boost package fail to compile --------------------------------+------------------------------------------- Reporter: macdev@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Not set | Milestone: Component: ports | Version: 1.9.2 Keywords: | Port: boost-gil-numeric --------------------------------+------------------------------------------- Dear maintainer of boost-gil-numeric, the gil examples which come with the boost package failed to compile on my system. Problems are caused by 2 lines in file /opt/local/include/boost/gil/extension/numeric/sampler.hpp The functions iround() and ifloor() are defined to return point2<std::ptrdiff_t> which is a long int on my system. That causes problems with related template definitions. You might want to conference the prototye definitions to be found in file /opt/local/include/boost/gil/utilities.hpp I created a diff:[[BR]] ===========================================================[[BR]] {{{ --- old_sampler.hpp 2011-04-18 12:58:09.000000000 +0200 +++ new_sampler.hpp 2011-04-18 12:57:08.000000000 +0200 @@ -45,7 +45,7 @@ template <typename DstP, typename SrcView, typename F> bool sample(nearest_neighbor_sampler, const SrcView& src, const point2<F>& p, DstP& result) { - point2<int> center(iround(p)); + point2<std::ptrdiff_t> center(iround(p)); if (center.x>=0 && center.y>=0 && center.x<src.width() && center.y<src.height()) { result=src(center.x,center.y); return true; @@ -101,7 +101,7 @@ template <typename DstP, typename SrcView, typename F> bool sample(bilinear_sampler, const SrcView& src, const point2<F>& p, DstP& result) { typedef typename SrcView::value_type SrcP; - point2<int> p0(ifloor(p)); // the closest integer coordinate top left from p + point2<std::ptrdiff_t> p0(ifloor(p)); // the closest integer coordinate top left from p point2<F> frac(p.x-p0.x, p.y-p0.y); if (p0.x < 0 || p0.y < 0 || p0.x>=src.width() || p0.y>=src.height()) return false; }}} [[BR]] ===========================================================[[BR]] Best regards, macdev -- Ticket URL: <https://trac.macports.org/ticket/29196> MacPorts <http://www.macports.org/> Ports system for Mac OS
