Hi srifenbark,


I am Nikhil working as soft ware engineer in kerala.

Currently i am working with a project which require yocto based file system.
I am using sama5d36-xplained evaluation kit.

Based on the information from the following site
http://www.at91.com/linux4sam/bin/view/Linux4SAM/YoctoProject build a file
system which support qt images and tested successfully.

Is there any way to  avoid this demo images from this build and add qt
support for bitbake core-image minimal process.


Regards
Nikhil

[yocto] Yocto update to Sumo with Multilib results in error in do_image_wic

[baisch]

After the update to Yocto 2.5 Sumo my genericx86 build doesn't work anymore. 
The problem seems to be with the Multilib feature. I need the 64 bit version of 
grub-efi so I've added this to my local.conf:

  require conf/multilib.conf
  MULTILIBS = "multilib:lib64"
  DEFAULTTUNE_virtclass-multilib-lib64 = "x86-64"
  IMAGE_INSTALL_append = " lib64-grub-efi"

With Sumo I get this error:

  image-dev-1.0-r0 do_image_wic: Error executing a python function in 
exec_python_func() autogenerated:

  […]

  Subprocess output:
  sed: can't read 
/workdir/poky/build-x86/tmp/work/genericx86-poky-linux/image-dev/1.0-r0/recipe-sysroot/usr/bin/crossscripts/x86_64-pokymllib64-linux-libtool:
 No such file or directory

The file `x86_64-pokymllib64-linux-libtool` is in 
`genericx86-pokymllib64-linux/image-dev/1.0-r0/lib64-recipe-sysroot/usr/bin/crossscripts/`
 (Note the difference: `lib64`). If I copy it over just to see what happens, 
another error pops up:

  ERROR: image-dev-1.0-r0 do_image_wic: Error executing a python function in 
exec_python_func() autogenerated:

  […]

  Exception: FileExistsError: [Errno 17] File exists: 
'/workdir/poky/build-x86/tmp/sysroots-components/x86_64/lib64-glibc/sysroot-providers/virtual_lib64-libc'
 -> 
'/workdir/poky/build-x86/tmp/work/genericx86-pokymllib64-linux/image-dev/1.0-r0/lib64-recipe-sysroot/sysroot-providers/virtual_lib64-libc'

  ERROR: image-dev-1.0-r0 do_image_wic: Function failed: extend_recipe_sysroot

Did something fundamentally change with Multilib in Sumo? I scanned the manual 
but it seems that I don't have to do anything different than before. 
https://www.yoctoproject.org/docs/2.5/mega-manual/mega-manual.html#using-multilib

When I comment the Multilib lines from the local.config it builds without 
errors.
