c++ - Simple OpenCV program won't run; given no errors. What now? -

-

i'm working on term project school , plan use opencv. i've spent past day or battling include/link errors (mostly because of dumb mistakes) , have working. or thought.

i have simple program, looks this:

#include <highgui.h> int main() {     cvnamedwindow("window", cv_window_autosize);     cvwaitkey(0);     return 0; }

no errors appear in eclipse, , bold-faced / looking should library functions (can't remember proper formatting name called). when compile it, succeeds. no errors. when run this, nothing happens. , it's @ point i'm stuck.

i'm using opencv @ work , modeled setup @ home accordingly (nearly identically actually). include paths, library paths, , libraries added in project eclipse (at least, w.r.t work setup). dll's in same folder executable.

any ideas why doesn't run? (the window doesn't display, instantly terminates)

i should mention i'm using eclipse (helios), mingw, windows 7, , opencv 2.3.

cheers.

try compiling command prompt, run executable command prompt, see happens. how compile 

g++ -o main.exe main.cpp -i"c:\opencv2.1\include\opencv" -l"c:\opencv2.1\lib" -lcxcore210 -lcv210 -lhighgui210 -lcvaux210 -lml210

note: have used opencv 2.1. set 1 accordingly. , have added opencv bin folder path, makes easier find dll files executable file.

actionscript 3 - TweenLite does not work with object -

-
i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
