Hi guys, i am trying to run a GUI application inside mini2440(FriendlyARM board that runs Qtopia). I followed instructions from http://mini2440vietnam.blogspot.com/2011/05/programming-application-for-... & the following from "tslib & Qt compilation" compilation http://mini2440vietnam.blogspot.com/2011/04/upgrade-qt462-in-mini2440.html i have set up necessary environment on my machine and also in Qt Creator as given in the blog. i have followed all the instructions from this blog, but when i try to execute this application inside ubuntu bash terminal (here i am connected to mini2440 using telnet and the GUI application binary is in "/opt/Qtopia/bin") i get the following error [root@FriendlyARM bin]# ./HelloWorld QWSDisplay::Data::init: Invalid argument Client can't attach to main ram memory. Aborted what is the problem here, was there any mistakes during my compilation.?? now that i understand that this is terminal and can't run GUI apps, but when i try to run this application inside mini2440 board, nothing happens, Qtopia/system doesn't even recognizes the binary and "?" sign appears as the application icon. What is wrong with this?? and what will i have to do to make this happen(run GUI application compiled from Qt Creator 2.0.1 in Linux) ??? thankyou.
