I am currently working on yocto project.
Am running my OpenCV code in ARM. am using meta-ti and meta-openembedded layer am getting error like:
OpenCV Error: Unspecified error (GStreamer: your gstreamer installation is missing a required plugin
) in handlemessage, file /usr/src/debug/opencv/3.1+gitAUTOINC+92387b1ef8-r0/git/modules/videoio/src/cap_gstreamer.cpp, line 1692
terminate called after throwing an instance of 'cv::Exception'
what(): /usr/src/debug/opencv/3.1+gitAUTOINC+92387b1ef8-r0/git/modules/videoio/src/cap_gstreamer.cpp:1692: error: (-2) GStreamer:n
in function handlemessage.
I am using bitbake core image-sato
the code is cross compiled with toolchain and i build it.. is working fine but it showing error on board.
it asking gstreamer but gstreamer is already there in meta-oe there..

When running the project on a simulator everything seems to work fine. Once i tried to deploy to an actual device I get the following error:

Make sure you have added flutter we bauth dependency plugin in your pubspec.yaml
dependencies:
flutter_web_auth: ^0.1.3
If it's added and it still does not works, ensure also that the pod install works fine to add the plugin.
While compiling cobalt for raspberry pi on ninja, im getting an error like this:
undefined reference to symbol 'eglCreateImageKHR'
here is the full trace:

I googled it and found somewhat related article on this site.
As per this article the fault could be that of libssl1.0-dev not being there. I checked and found it was libssl-dev. Replaced it with libssl1.0-dev but still the error persists.
Can somebody tell me what is going wrong?
eglCreateImageKHR() is an EGL extension EGL_KHR_image. Since Cobalt compiled, it appears the headers declare the extension, but the linked EGL library didn't define it. It's surprising that only eglCreateImageKHR() is missing and not eglDestroyImageKHR as well.
At any rate, I recommend trying to update the EGL library, but I'm not familiar with the raspi install, so can't tell you the specifics.
Alternatively, it is safe to comment out the call to that function in decode_target_create.cc since SbImageIsDecodeSupported() always returns false for raspi (see image_is_decode_supported.cc), so decode targets should never be created / destroyed on the platform. (Decode target support is a work in progress for raspi.)
I resolved this by changing the os itself. The problem was that the cobalt was not compatible with raspi stretch but with raspi jessie. Because sysroot files are being copied from the OS it was creating that error. I don't know exactly where the difference is but changing to raspi jessie worked fine for me.
I've been trying to install Tensorflow and get it working over the past few days. Whilst I have managed to install TF and get it working as tested by opening Python in the terminal and typing,
import tensorflow as tf
I have not been successful attempting to retrain Inception v3. I managed to install it from source once by following the instructions laid out here however I am no longer able to do so. When I get to the section 'Create the pip package and install' and go to run bazel build -c opt //tensorflow/tools/pip_package:build_pip_package in the root of my Tensorflow directiory I get the following error.
kieran#kieranUbuntu:~/tensorflow$ bazel build -c opt //tensorflow/tools/pip_package:build_pip_package

This is the same error I ran into when I managed to install it and then attempted retaining the classifier following this tutorial. At the section, bazel build tensorflow/examples/image_retraining:retrain.
I just can't figure out what is going wrong and I have been trying for so long.
I'm using this pip version, # Ubuntu/Linux 64-bit, CPU only, Python 2.7
I think you should search before ask, This link can probably solve your issue.
The issue lied in the incorrect use of ./configure. Whilst it was ran I currently have two versions of python on my computer, both of which are stored in different locations, when running ./configure I pointed it to the wrong python version. After rectifying the issue everything worked correctly.
I'm starting out with QT creator
My objective is to use it to create a Application using Qt3D and QT quick Ui
When I try to create a project it shows me I don't have a compiler yet: (screenshot on link)
QT new project, no compiler error
If I try to build an example it shows me the following error:
16:35:11: Configuration is faulty. Check the Issues view for details.
Error while building/deploying project shadow-map-qml (kit: Desktop Qt 5.6.0 MSVC2015 64bit)
When executing step "Make"
Did I do something wrong on the installation or Do I need to download and install a separate compiler? If so for Qt 5.6 on windows 10 which should I download?
I'm cross-compiling my first program with OpenCV on the BeagleBone.
I use Eclipse Juno IDE, arm-angstrom-linux-gnueabi-gcc compiler and the last OpenCV library.
I've successfully built program with OpenCV on my PC, I've successfully cross-compiled "Hello Wolrd" onto my BB, then I've tried to cross-compile OpenCV on BB.
I just linked OpenCV libraries (opencv_highgui, without changing my "hello world" code) and after compiling got the following errors:
/usr/local/angstrom/arm/lib/gcc/arm-angstrom-linux-gnueabi/4.3.3/../../../../arm-angstrom-linux-gnueabi/bin/ld: skipping incompatible /usr/lib/libopencv_highgui.so when searching for -lopencv_highgui
/usr/local/angstrom/arm/lib/gcc/arm-angstrom-linux-gnueabi/4.3.3/../../../../arm-angstrom-linux-gnueabi/bin/ld: skipping incompatible /usr/lib/libopencv_highgui.a when searching for -lopencv_highgui
/usr/local/angstrom/arm/lib/gcc/arm-angstrom-linux-gnueabi/4.3.3/../../../../arm-angstrom-linux-gnueabi/bin/ld: cannot find -lopencv_highgui
Arm compiler ignores this lib, and I don't know why.
How can I fix this problem?
