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

[Bryce Salmi]

Qt List,

    Thank you for your help!  I have figured out the problem and the fix
was found on Qtforums.com
(http://www.qtforum.org/article/27787/tuto-how-to-install-qt-embedded-li
nux-4-5-1-on-arm-board-phycore-i-mx31-from-phytec.html ) by adapting the
posts methods for the board I am working with. I have run into another
problem though.  I tried to run the framebuffer test program (will not
work due to lack of mmap support at this time) but I also tried to run
the widget "analogclock".  When I try to run this in terminal I get
this:

 

# ./analogclock -qws
Initializing QFontEngineQPF failed for
/usr/local/Trolltech/QtEmbedded-4.5.1-arm
/lib/fonts/DejaVuSans.ttf
Initializing QFontEngineQPF failed for
/usr/local/Trolltech/QtEmbedded-4.5.1-arm
/lib/fonts/DejaVuSans-Bold.ttf

 

I would really appreciate any help with this issue.  Deleting the fonts
results in no error messages but it still seems like the program hangs
just like it does with the previous error messages.  The .cpp source
file for analog clock does not seem to call any fonts either so this may
be a Qt related problem?  Could the lack of output be related to no mmap
support?  Does Qt use mmap in all its applications or does it differ?
Thank you for your time!

 

 

 

 

Sincerely,

Bryce

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
