when i want run my program in mini2440. i seen this error: ./armNEW: error while loading shared libraries: libQtGui.so.4: cannot open shared object file: No such file or directory and when i googling i see this link: http://www.friendlyarm.net/forum/topic/1403#9580 that they say look for libs in /usr/local/Qt / libraries but i dont have Qt folder that contains Qt libs. now what can i do now?
Google <ini2440vietnam> and read through his tutorial on Qt.
Hi and thanx for yuor reply. I saw that, and i do those : 3. Loading automatically my own program before qtopia The first thing we should do is to stop qtopia, do this: $cd /etc/init.d/ $vi rcS Comment last three lines: #bin/qtopia& #echo" "> /dev/tty1 #echo"Starting Qtopia, please waiting..." > /dev/tty1 Reset the board, you will see that there is no qtopia desktop anymore but a black screen. The second thing we do is to add the code to run our own program, for example, our program has a name as "ex1" and it is located in /mnt/ex1. In this step, we will make some changes from the files in article Upgrade Qt4.6.2 $cd /etc/ $vi profile Cut those line: export LD_LIBRARY_PATH=/usr/local/tslib/lib export QTDIR=/usr/local/Qt export QWS_MOUSE_PROTO=tslib:/dev/input/event0 export TSLIB_CALIBFILE=/etc/pointercal export TSLIB_CONFFILE=/usr/local/etc/ts.conf export TSLIB_CONSOLEDEVICE=none export TSLIB_FBDEVICE=/dev/fb0 export TSLIB_PLUGINDIR=/usr/local/tslib/lib/ts export TSLIB_TSDEVICE=/usr/local/tslib/lib/ts export TSLIB_TSEVENTTYPE=INPUT export QWS_DISPLAY=LinuxFB:mmWidth=105:mmHeight=140 Close and save it. Then: $cd /etc/init.d/ $vi rcS Paste above lines into the end of this rcS file, and add following line into the end of rcS file too ./mnt/ex1 -qws i mean when i open "profile" at the first, there is no command like the site says. but i copy them from site to /etc/init.d/rcS but i have that error :./armNEW: error while loading shared libraries: libQtGui.so.4: cannot open shared object file: No such file or directory (i change my app name from ex1 to armNEW) helppppppppppppppppp meeeeeeeeee plzzzzzzzzzzzzzz :(
Well, looking at the error msg .... where is libQtGui.so.4 located on your target?
hi i do at first again 1: install linux on mini2440 2: copy the libs (tslib and /usr/local/Qt/lib (my first problem is solved and i find i should copy that directory from pc to board to make /usr/local/Qt/lib)) 3: when i run my program i see this error again : [root@FriendlyARM usb]# ./armNEW -qws ./armNEW: error while loading shared libraries: libQtGui.so.4: cannot open shared object file: No such file or directory libQtGui.so.4 is placed in : [root@FriendlyARM /]# find -name "libQtGui.so.4" ./usr/local/Qt/lib/libQtGui.so.4 ./usr/local/Trolltech/QtEmbedded-4.6.3-arm/lib/libQtGui.so.4 but i dont know what is the meaning of this error?
Going back a post or two ... > i mean when i open "profile" at the first, there is no command like the > site says. I think you mean no file like that. I think you are doing the right thing putting those environment variables into /etc/init.d/rcS You seem to have the correct library path export QTDIR=/usr/local/Qt http://www.friendlyarm.net/forum/topic/4853 near the bottom was a solution? to someone's problem. You did do a readelf on the cross-compiled libQtGui.so.4 as per the other recent QT thread? Can you do a ts_calibrate?
Another tutorial: https://suchakra.wordpress.com/2011/05/17/qt-on-mini2440/
Try this ... libQtGui.so.4 is a link to libQtGui.so.4.8.4 on my system. Is libQtGui.so.4 a link to libQtGui.so.4.x.x on your system? I read something about copying symbolic links from your host to your target, ie maybe something gets messed up. Does libQtGui.so.4 show as a valid link on your target?
