I am trying to build opencv.js by following the steps mentioned in the Open CV [official document][1].
Note: I am trying to make a custom build instead of using the existing [opencv.js][2] library because I want to add some contrib modules as well.
Open CV source version: 4.5.1
Cmake: 3.20.0
Python: 3.7
Emscriptem: [latest][3]
operating system: windows 64 bit
The below is the stack trace of the issue I get when I try to execute the below command in the windows power shell..
emcmake python ./opencv/platforms/js/build_js.py build_js

Any ideas to resolve this issue is appreciated.
Building opencv.js on Windows will NOT work, at least according to this open issue. An alternative is to install WSL and use it to build.
When I compile caffe for windows (64bit, release, vs 2013, nvidia 750, opencv 3.1,cuDNN version 5.1), I got the following error
"Error 13 error C1083: Cannot open include file: 'cudnn.h': No such
file or directory ...\caffe\util\cudnn.hpp 5 1 convert_imageset".
I set everything like what mentioned in this video.
I search for this error in github issues link this and this
if I use version 4 of cuDNN and OpenCV 2.4I got:
========== Rebuild All: 15 succeeded, 1 failed, 0 skipped ==========
However, I got error:
Error 1 error MSB3073: The command
""...\caffe-master\windows\scripts\BinplaceCudaDependencies.cmd"
"C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v7.5\bin"

Extract the cuDNN archive to a directory of your choice, referred to below as installpath. Then follow the platform-specific instructions as follows:
Add installpath to the PATH environment variable.
In your Visual Studio project properties, add installpath to the Include Directories and Library Directories lists and add cudnn.lib to Linker->Input->Additional Dependencies.
I am trying to compile OpenCV with Cuda support using Microsoft Visual Studio 2013 and get the following compilation error message:
22> CMake Error at cuda_compile_generated_pyrlk.cu.obj.cmake:264 (message):
22> Error generating file
22> F:/Nir/dev/opencv/build/visualStudioA/modules/cudaoptflow/CMakeFiles/cuda_compile.dir/src/cuda/Debug/cuda_compile_generated_pyrlk.cu.obj

22>C:\Program Files\MSBuild\Microsoft.Cpp\v4.0\V120\Microsoft.CppCommon.targets(170,5): error MSB6006: "cmd.exe" exited with code 1.
Is there a way to get more information about the error?
Increasing log verbosity, or getting the nvcc command that failed could be useful
Cuda compile verbosity can be enabled at CMakeCache.txt file:
//Print out the commands run while compiling the CUDA source file.
// With the Makefile generator this defaults to VERBOSE variable
// specified on the command line, but can be forced on with this
// option.
CUDA_VERBOSE_BUILD:BOOL=ON

Hello everyone,
I'm trying to just compile and run an HTML5 App for ubuntu Phone, but after trying and searching for a week now, I still can't make it run !
For the moment I just want to run the simple html5 app template.
This is the situation :
I have installed ubuntu sdk as instructed in https://developer.ubuntu.com/en/start/ubuntu-sdk/installing-the-sdk/
I've created in the run click menu, an i386 build target. (15.04) --- which exited with no errors
I created an i386 emulator in devices --> i386 - devel - default password --- which is finally up and running correctly
The problem is when I compile the default template : theses are the errors I get :
desktop_Exec(app): found unexpected Exec with architecture 'all':./qtc_device_debughelper.py
security_policy_groups_safe_app(debug):(REJECT)reserved policy group 'debug':not for production use
security_policy_version_matches_framework(app.apparmor):invalid framework 'ubuntu-core-15.04'
And when I try to edit it anyway :
This is what I get :
Traceback (most recent call last):
File "/tmp/qtc_device_applaunch.py", line 29, in <module>
gi.Repository.get_default().require("UbuntuAppLaunch")
gi.RepositoryError: Typelib file for namespace 'UbuntuAppLaunch' (any version) not found
During handling of the above exception, another exception occurred:
Traceback (most recent call last):

AttributeError: 'DynamicImporter' object has no attribute 'find_spec'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/tmp/qtc_device_applaunch.py", line 33, in <module>
from gi.repository import UpstartAppLaunch as UAL
File "/usr/lib/python3/dist-packages/gi/importer.py", line 53, in find_module
'introspection typelib not found' % namespace)
ImportError: cannot import name UpstartAppLaunch, introspection typelib not found
I have been looking for this everywhere but I couldn't find something that works.
I need some of your knowledge to help me understand all this!
I have the same errors. I think that the 'ubuntu-core-15.04'-error is related to the version of Ubuntu you are using. I use Mint 17, which is based on Ubuntu 14.04. Canonical recommends the newer Ubuntu Versions for app-developing, because there is some stuff in it they changed.
unfortunately, I can't help you with the other errors.
I just downloaded the Cocos2d-x SDK and tried to compile the hello world example with the following result:
<code>The Selected NDK toolchain version was 4.8 !

Which cocos2d-x version are you using? Seems like you didn't define your env variables correctly. Please have a look at this tutorial and make sure you define the following variables:
COCOS2DX_ROOT : should point to the root directory of cocos2d-x
ANDROID_SDK_ROOT : Should point to the root directory of the Android SDK
NDK_ROOT : Should point the to root directory of the Android NDK
NDK_TOOLCHAIN_VERSION : Which Android NDK toolchain should be used
See the problem is that the system is not able to compile the cocos.py.
So, if you open cocos.py from the bin directory where you have unzipped the file
it runs smoothly.
The thing is Python3.x is not able to compile the Phython2.x code.
So we must change the path in environment variable so the system doesn't a python2 file with the help of python3 compiler.
Thanks
Summary
1.Go to Control Panel, then type path or environment in search bar
2.open Evnvironment variables
3.Just delete any C:\Python34 or anything starts with python3.x and add C:\Python27 path where you have installed.
