compiler errors - when use cygwin g++ to build a project , can't find the include head file even if I have indicated path with -I -


i knew there punch of kind problem bother . it's weird me . please patient let me finish problem statement .

background : windows vista , cygwin latest version , opencv 2.4.3

my project make file opencv installed in d:\application\opencv2.4.3\opencv :

opencv=/cygdrive/d/application/opencv2.4.3/opencv/build custom_includes+=-i${opencv}/include -i${opencv}/include/opencv -i${opencv}/include/opencv2/ml -i${opencv}/include/opencv2/highgui -i${src_dir} custom_libraries+= -l${opencv}/x86/mingw/lib -lopencv_core -lopencv_highgui -lopencv_imgproc -lopencv_objdetect

and head file need build :

#include <iostream> #include <string> #include <opencv2/core/core.hpp> #include <opencv2/core/core_c.h> blablabla...

when execute :

g++ -c src/objectdetector.cpp -wall  -o3 -ffast-math -funroll-loops   -i/cygdrive/d/application/opencv2.4.3/opencv/build/include -i/cygdrive/d/application/opencv2.4.3/opencv/build/include/opencv -i/cygdrive/d/application/opencv2.4.3/opencv/build/include/opencv2/ml -i/cygdrive/d/application/opencv2.4.3/opencv/build/include/opencv2/highgui -isrc/ -o build/objectdetector.o

oops, turn out :

    in file included src/objectdetector.cpp:10:0: src/objectdetector.h:15:33: fatal error: opencv2/core/core.hpp: no such file or directory

i 100 persent sure opencv2/core/core.hpp in /cygdrive/d/application/opencv2.4.3/opencv/build/include , , use "" substitute <> . none of these works , pained . have referenced every google search item . pls me out .

thanks .

it looks trying mix mingw-compiled opencv cygwin; won't work. if want use opencv on cygwin, try installing libopencv-devel package cygwin ports.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
