I'm trying to start learning OpenCV but I can`t even create the framework.
I'm using this command like the instructions said
python opencv/ios/build_framework.py ios
But I'm getting the following error:
** BUILD FAILED **
The following build commands failed:
Libtool /Users/myName/Documents/Apps/Frameworks/ios2/build/iPhoneSimulator-i386/modules/world/UninstalledProducts/libopencv_world.a normal i386

I don't know what to do! Please help
Try this:
$ git checkout 2.4.3 # or 2.4.4 or 2.4.3.1 or 2.4.3.2
...somewhere in your opencv checkout before you run
$ python ./build_framework.py <SOME_DIR_OUTSIDE_OF_OPENCV_SOURCE_TREE>

I do not know what the problem is. If I start container and build it manually it works.
If I create it manually then I am getting following error:
Conan: Version found ERROR: Can't write version file in /.conan/version.txt
I added the following environment variable to my jenkinsfile. Then it simply works!. I was trying to define env variables in docker container that was my fail
environment {
CONAN_USER_HOME = "${env.WORKSPACE}/"
CONAN_NON_INTERACTIVE = 1
}
I am trying to lock a pipfile and I am getting the following error (on Windows 10). Any tips on how to resolve this? I have tried updating pipenv, wheel, and setuptools.
The code is pulled from a repo which works fine for others.

I am trying to buiil Dart-VM on windows, I follow the steps as described here
https://github.com/dart-lang/sdk/wiki/Building
When I run the build.py command as below:
.\tools\build.py --mode release --arch x64 create_sdk
I get the following error:

It seems missing the args.gn file in out\ReleaseX64 folder. but I cannot find args.gn in Dart source folders. Is it generated during building process? whether I do wrong steps led to no such file generated?

This error happens because cmake is either (a) not installed or (b) not on the user's path.
In this case, the OP had downloaded the cmake gui application from cmake.org, and copied it to /Applications. This app doesn't add the path to the binaries automatically, which is why the script couldn't find cmake.
By adding the path to the cmake binaries (bash syntax):
PATH=$PATH:/Applications/CMake.app/Contents/bin
the OP was able to successfully build opencv.
Most package managers - e.g. homebrew or macports whould have automatically added a path to the user's profile that would have permitted it to run without having to modify the path any more.
You may need to install CMake
My-Mac: opencv$ brew install cmake
I've followed the directions here to build html documentation https://code.ros.org/trac/opencv/browser/trunk/opencv/doc/README.txt (actually my local copy that came with OpenCV 2.2, but they are the same), but I get this error after running sh buildall:

The pdf file built fine but I prefer html.
I'm using Ubuntu 10.10.
I was able to get this working by simply doing "mkdir parse-cache" in the opencv/doc/latex2sphinx directory.
