c++ - How can I check a running process to see what shared libraries it is using? -


on linux, have c++ application using dlopen() load shared libraries, i'm suspicious version of shared library being loaded not 1 expect because debugging trace code not appear executed.

is there way check running process query shared libraries has open , path each of libraries? in other words, akin ldd works on running executable , lists runtime loaded libraries well.

if want know library files program have opened, can try pmap. example, if want know libraries bash process 3860 have opened, result be:

3860:   bash 08048000    880k r-x--  /bin/bash 08124000      4k r----  /bin/bash 08125000     20k rw---  /bin/bash 0812a000     20k rw---    [ anon ] 099ae000    348k rw---    [ anon ] b715c000     44k r-x--  /lib/i386-linux-gnu/libnss_files-2.15.so b7167000      4k r----  /lib/i386-linux-gnu/libnss_files-2.15.so b7168000      4k rw---  /lib/i386-linux-gnu/libnss_files-2.15.so b7169000     88k r-x--  /lib/i386-linux-gnu/libnsl-2.15.so b717f000      4k r----  /lib/i386-linux-gnu/libnsl-2.15.so b7180000      4k rw---  /lib/i386-linux-gnu/libnsl-2.15.so b7181000      8k rw---    [ anon ] b7183000     28k r-x--  /lib/i386-linux-gnu/libnss_compat-2.15.so b718a000      4k r----  /lib/i386-linux-gnu/libnss_compat-2.15.so b718b000      4k rw---  /lib/i386-linux-gnu/libnss_compat-2.15.so b71a1000      4k r----  /usr/lib/locale/locale-archive b71a2000   1428k r----  /usr/lib/locale/locale-archive b7307000   2048k r----  /usr/lib/locale/locale-archive b7507000      4k rw---    [ anon ] b7508000   1676k r-x--  /lib/i386-linux-gnu/libc-2.15.so b76ab000      8k r----  /lib/i386-linux-gnu/libc-2.15.so b76ad000      4k rw---  /lib/i386-linux-gnu/libc-2.15.so b76ae000     16k rw---    [ anon ] b76b2000     12k r-x--  /lib/i386-linux-gnu/libdl-2.15.so b76b5000      4k r----  /lib/i386-linux-gnu/libdl-2.15.so b76b6000      4k rw---  /lib/i386-linux-gnu/libdl-2.15.so b76b7000    112k r-x--  /lib/i386-linux-gnu/libtinfo.so.5.9 b76d3000      8k r----  /lib/i386-linux-gnu/libtinfo.so.5.9 b76d5000      4k rw---  /lib/i386-linux-gnu/libtinfo.so.5.9 b76d8000     28k r--s-  /usr/lib/i386-linux-gnu/gconv/gconv-modules.cache b76df000     40k r-x--  /lib/i386-linux-gnu/libnss_nis-2.15.so b76e9000      4k r----  /lib/i386-linux-gnu/libnss_nis-2.15.so b76ea000      4k rw---  /lib/i386-linux-gnu/libnss_nis-2.15.so b76eb000      8k rw---    [ anon ] b76ed000      4k r-x--    [ anon ] b76ee000    128k r-x--  /lib/i386-linux-gnu/ld-2.15.so b770e000      4k r----  /lib/i386-linux-gnu/ld-2.15.so b770f000      4k rw---  /lib/i386-linux-gnu/ld-2.15.so bfbbf000    132k rw---    [ stack ]  total     7152k

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...
