Cross compilation with X11
-
Hi,
Yes I have mounted on the place as I had while cross compiling.I have permission to read/write but as a root. Its as shown below:
@drwxr-xr-x 2 root root 4096 Jun 11 2013 cdrom
drwxrwx--- 2 root vboxsf 4096 Jun 12 2013 sf_UbuntuSharedFolder
drwxr-xr-x 1 root root 4096 Oct 6 11:28 SSHFS_X11@ -
Hi,
I resolved that issue. The problem was while mounting the file system using ssfhs I had not provided an option i.e allow_other. So it was showing permission denied error
Thank you. -
Hi,
All my problem solved. Now Qt application is running on gnome.
Thank you so much for the help :) :) -
You're welcome !
Since you have your application working now, please update the thread title prepending [solved] so other forum users may know a solution has been found :)

Hi,
Ya sure I will do it.
I have one more problem. Keyboard is not working after running the application.
How can I enable it? -
How are you starting your application ? What type of keyboard is it ?
-
I am using USB Keyboard.
I am starting the application by giving the command in the terminal:
@./Test_app@Keyboard works till application runs after application start running it doesn't work.
-
Still using X11 ?
-
Yes Qt application running on X11.

Is it possible build without target device ?
Can you explain what you mean?
You can build without target device if you have a sysroot for it. -
I have mounted target device on /media/SSHFS_X11/ path on host machine (Ubuntu). While mounted Qt getting build, If I disconnect the target device. I am getting following error:
Basic XLib functionality test failed!
You might need to modify the include and library search paths by editing
QMAKE_INCDIR_X11 and QMAKE_LIBDIR_X11 in /home/lolveley/bin/qt-x11-opensource-src-4.5.1/mkspecs/linux-g++.May I know how to build without target device ? And how to configure sysroot on host (Ubuntu) machine ?
Could you please help me on this...

I have copied /usr dir files to /media/SSHFS_X11, and tried to build But still and getting following error,
Basic XLib functionality test failed!

QMAKE_INCDIR_X11 and QMAKE_LIBDIR_X11 in /home/lolveley/bin/qt-x11-opensource-src-4.5.1/mkspecs/linux-g++.Is it required to copy all the contents or /usr dir is fine?
Target device also Ubuntu OS stand alone device.
-
@thanga You need to copy everything what is needed. You should copy at least /usr/lib and /usr/include, probably /lib as well.
It should then look like:/media/SSHFS_X11/usr/include /media/SSHFS_X11/usr/lib /media/SSHFS_X11/libCall configure with -v parameter to see what exactly is missing if it says "Basic XLib functionality test failed!".
-
If you don't use the same folder as you did when configuring the first time then you should point configure to the new location. Note that you should do a build from scratch to avoid any leftovers from interfering.

Does this header file exist in /media/SSHFS_X11/usr/include ?

Did you do a full copy of the sysroot over to your desktop ?
On a side note, unless you're locked to that version, at least use the latest of the Qt 4 series which is 4.8.7. Even better if you migrate to Qr 5.
