Glibc-2.17 toolchain issue iconv folder undefined reference -


on building glibc on toolchain . libraries make succesfully (and test ok) flags unset except specified building default glibc. start building programs both , without flags on seperate fresh build attempts , every time in iconv folder breaks...

i'll diverge second moan how iconv breaks in glibc me , has done long can remember... moving on though....

after 2 weeks of trying compile every way possible im getting bit fed up. ideas please?

a bit late, useful.

the symbols tsan , asan in name related address sanitizer project provides llvm clang , gcc tools detect , report whole range of problems related illegal memory access.

to use them have install tools , libraries, use correct versions of compilers , correct combinations of flags during compile , linking depending on version.

in experience documentation useful, , topic pretty advanced. in project on have full control, ended disabling 1 commandline parameter -fsanitize=address recommended -fno-omit-frame-pointer both compile , link (gcc 4.8 on x64 ubuntu 14.04lts).

since attempting build existing project, @ mercy of settings. @ docs project , try determine recommended versions of compiler , sanitizer tools there, or maybe configuration options disable if don't care.

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...
