kdevelop - KDevelop4 linking to external library -


i'm trying setup kdevelop gcc, can't link external libraries. following error:

/home/tahsin/projects/glwrap/build> make linking cxx executable glwrap cmakefiles/glwrap.dir/main.cpp.o: in function `main': /home/_/projects/glwrap/main.cpp:11: undefined reference `glutinit' collect2: error: ld returned 1 exit status make[2]: *** [glwrap] error 1 make[1]: *** [cmakefiles/glwrap.dir/all] error 2 make: *** [all] error 2 *** failed ***

my code simple opengl file:

#include <gl/gl.h> #include <gl/glu.h> #include <gl/glut.h> #include <cassert>  using namespace std;  int main(int argc, char **argv)  {     glutinit(&argc, argv); }

i can of course compile file fine command line makefile, not kdevelop. i've tried setting cmakelist (although i'm new this, use makefiles). cmakelist associated kdev project looks this:

cmake_minimum_required(version 2.8) project(glwrap) set(cmake_cxx_flags "-lglut -lglu -lgl -i/path/to/the/include/dir") include_directories( /usr/include ) include_directories( /usr/lib ) include_directories( /usr/include ) link_directories( /usr/lib64 ) link_directories( /usr/lib32 )  add_executable(glwrap main.cpp) install(targets glwrap runtime destination bin)

is there specific needs set gui?

i'm not cmake expert, believe problem cmake needs in finding glut includes. 2 solutions might work are:

  1. find them , insert additional explicit include_directories( ) commands in cmakelist file program.
  2. (this uses powerful feature of cmake system.) use cmake findglut command. (check cmake documentation findxxx usage.) cmake glut files you.

in either case, after inserting changes cmakelist file, should run configure command in kdevelop4 project menu. cmake execute cmakelist changes , report if glut files found.

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...
