[Qt-embedded-interest] Qt Embedded on ARM Development Board

[fares.abdullah at sosco.com]

Hi Bryce,

"./hello: not found" sounds like a more fundamental (simple?) issue. Could it be a permissions problem (file is not executable), for example? You can try "ls -al" to see all permissions.

If that is OK, then you can check the "hello" file using the "file" utility, to make sure it is the architecture and format and linkage you expect it to be:
# file hello

If you don't have the "file" utility in your distribution then you can use a desktop machine running Linux or Windows+Cygwin.

Cheers,

- Fares

Qt Embedded List,
     I am currently trying to get Qt Embedded to run on an ARM 11 development board (about 35 Mb on-board memory with 256 Mb Ram) running a very simple version of Linux and a busybox shell.  I have followed the installation instructions as closely as possible on the Trolltech website and I believe that the cross compiler is statically built on my computer correctly.  The resulting "hello world" type application using code from the Trolltech tutorial builds successfully and is in ELF ARM file format and about 10 Mb large (seems right for static builds).  I mount a network drive with the development board and try to run the program on the ARM board (since it doesn't have much on-board memory) however, I get the error:

# ./hello
-sh: ./hello: not found
# ./hello -qws
-sh: ./hello: not found

     This occurs even though the file is obviously there with the "ls" command and also occured when I tried to run it dynamically with the library folder mounted to my /usr/lib directory on the board and the 14Kb hello application residing physically on the board.  That made me think it was a library issue which is why I built the compiler statically... Any ideas?  I would really like to get this working and displaying on my LCD screen (/dev/fb0). It is very worrisome that it says the file cannot be found which seems very very very wrong.  Any help would be greatly appreciated!




Thank You,

Bryce
