Hi Ch'Gans,

Thanks for your valuable reply first of all.



127.0.0.1 is your local network node, so it's very unlikely it will ever
failed. This is all very basic Unix/networking knowledge...

You need to find out the IP address of your board, I don't know how your
computer is setup, nor do I know how your board is. So I'm sorry but I
can't help you on that one

PC is set with ubuntu14.04. And I'm using wandboard-solo rev-A0

Anyways i carried the following experiment


I gave a static address to wandboard by using
ifconfig eth0 192.168.73.55

ifconfig eth0 192.168.73.55 up

now with the
wandboard-solo:~# ifconfig

it shows the desired ip address

But when trying to ping the host PC using the wandboard is giving the
following error.

192.168.74.145 (192.168.74.145):56 data byte
sendto:Network is unreachable

do i need to alter anything else?


Interesting, can you try this then:

Not good, in a previous email you mentioned /opt/poky/1.6.1/..., and now it
seems to be /opt/poky/1.4.1/...

Which version of Poky are you really using?

I'm using 1.6.1, the previous

By giving the ./qtcreator.sh in the Qt5.3.1 directory
(/Qt5.3.1/Tools/QtCreator/bin)it pops with the logs

minda at minda-HP-dx2480-MT-VP562PA:~/Qt5.3.1/Tools/QtCreator/bin$ sh -x
./qtcreator.sh


*+ source
/opt/poky/1.4.1/environment-setup-armv7a-vfp-neon-poky-linux-gnueabi*
./qtcreator.sh: 2: ./qtcreator.sh: source: not found
+ which ./qtcreator.sh
+ me=./qtcreator.sh
+ test -L ./qtcreator.sh
+ dirname ./qtcreator.sh
+ bindir=.
+ cd ./../lib

LD_LIBRARY_PATH=/home/minda/Qt5.3.1/Tools/QtCreator/lib:/home/minda/Qt5.3.1/Tools/QtCreator/lib/qtcreator
+ export LD_LIBRARY_PATH

i'm puzzled how 1.4.1 is coming there.But i've conformed that i'm using the
1.6.1 by verifying the /opt/poky


One key question you need to ask yourself is whether you need Qt4 or Qt5.
Can you answer that?

we wanna use Qt5


If you keep changing your environment all the time, we won't be able to
help, you might be interested in this FAQ:
http://catb.org/~esr/faqs/smart-questions.html

I could not access the URL.





 Have you tried the "bitbake meta-toolchain-qt5" command?

Try this:
$ cd /home/minda/bin/fsl-community-
bsp/
$ bitbake meta-toolchain-qt5


I cannot find the folder of mita-toolchain-qt5 in the
/home/minda/bin/fsl-community-bsp/sources

can you please provide the  url for cloning.

sorry i'm novice in this field



Thanks
