Apalis TK1 opencv bitbake failed

Hi.
Im trying to bitbake image for Apalis TK1 with opencv but I got that error:

Collected errors:

  • check_data_file_clashes: Package linux-driver-package-dev wants to install file /home/odroid/Openembedded_TK1/oe-core/build/tmp-glibc/work/apalis_tk1-angstrom-linux-gnueabi/angstrom-lxde-image/V2.7-r0/Apalis_TK1_LinuxImageV2.7/rootfs/usr/lib/libGL.so
    But that file is already provided by package * libgl-mesa-dev

  • opkg_solver_install: Cannot install package opencv.

I followed instructions on:

and

and use
bitbake -k angstrom-lxde-image
but I got that error at the end of process.
If I remove

IMAGE_INSTALL_append = " opencv"
from local.conf bitbake is producing image correct.

PS
I also have this warning:

WARNING: No recipes available for:
/home/odroid/OpenEmbedded_Apalis/oe-core/build/…/layers/meta-jetson-tk1/recipes-graphics/mesa/mesa_11.1.1.bbappend.

Is recipe for opencv 3.1 is broken??
Thanks

For opencv on the Apalis TK1, recommended recipe would be opencv4tegra. OpenCV for Tegra is a version of OpenCV that NVIDIA optimized specifically for Tegra platform family.

IMAGE_INSTALL_append = " opencv4tegra"

would be required in local.conf.

Also have a look at the OpenCV for Tegra documentation.

Thanks for that.
I added:

IMAGE_INSTALL_append = " cudatoolkit6.5"

IMAGE_INSTALL_append = " opencv4tegra"

and apply patches from morty-next branch.
Now it is compiling wit no errors but at the end of bitbake I got this error:

I solved this by changing in package_manager.py

output = subprocess.check_output(cmd.split(), stderr=subprocess.STDOUT).decode(“utf-8”)
to

output = subprocess.check_output(cmd.split(), stderr=subprocess.STDOUT).decode(“gb2312”,errors=“ignore”)

Bitbake process is now finished and generated image seems to work but im not sure if that is the proper way.
Thanks
