I downloaded OpenCV folder from GitHub and followed the ReadMe instruction to build it for ios.
After use python opencv/platforms/ios/build_framework.py ios command I have the following error:
Executing: ['cmake', '-GXcode', '-DAPPLE_FRAMEWORK=ON', '-DCMAKE_INSTALL_PREFIX=install', '-DCMAKE_BUILD_TYPE=Release', '-DIOS_ARCH=armv7', '-DCMAKE_TOOLCHAIN_FILE=/Users/name/Downloads/opencv/platforms/ios/cmake/Toolchains/Toolchain-iPhoneOS_Xcode.cmake', '-DENABLE_NEON=ON', '/Users/name/Downloads/opencv', '-DCMAKE_C_FLAGS=-fembed-bitcode', '-DCMAKE_CXX_FLAGS=-fembed-bitcode'] in /Users/name/Downloads/ios/build/build-armv7-iphoneos

What I have to do to fix it?
If someone in the future will have the same problem.
This problem was in the master branch, downloading branch 2.4 and adding CMake at PATH the build process go well
I also encountered the same problem.
In the master branch or 3.4 branch or 2.4 branch.
But after installing cmake, it will be fine.
In the 2.4 branch error message will show :
/bin/sh: cmake: command not found

I'm trying to install v8js on a local http/ssh server built with Debian 9.3, so I need to install v8 chromium engine first according to this documentation.

Obviously I can not continue the following installation steps (I can't use ninja) and I do not really know about Python so a help would be really convenient :)
PS: I saw (I don't remember where) that there is probably minimum RAM (8GB) and Disk space (100GB) requirements to build v8, is that it ...?
I'm getting errors when trying to install abpcrawler (Repository below).

Am I missing something? I have Mercurial installed and am able to clone the build tools repo.
Judging from the error message, /usr/bin/firefox couldn't be started because:
OSError: [Errno 2] No such file or directory
ABP Crawler requires Firefox to be installed, it will automate Firefox in order to collect data. If Firefox is actually installed, maybe the path is /usr/local/bin/firefox or something similar. You can run which firefox from the command line if you aren't sure.
How do I run/install this: https://github.com/kevmoo/kbuild?
I installed the dependencies and tried to execute the bin/kbuild Python script, but it's giving me this error:
Traceback (most recent call last):
File "kbuild/bin/kbuild", line 12, in <module>
BREW_PREFIX = subprocess.check_output(['brew', '--prefix']).strip()

raise child_exception OSError: [Errno 2] No such file or directory
My guess is that this tool was intended for OSX and Homebrew and that's why it's choking. I just wasn't sure based on the minimalist installation instructions.
Line 12:
BREW_PREFIX = subprocess.check_output(['brew', '--prefix']).strip()
is explicitly trying to run 'brew' in the shell, so yes I'd say it is written only for OSX.
I'd suggest you wait for your Issue to be answered on GitHub, or try modifying it yourself. It seems brew is only being used to check for available compilers.
I'm trying to set up django-nonrel into a new virtualenv, but am getting an error saying: OSError: [Errno 2] No such file or directory.
I can't tell from the error log exactly which file or directory is missing. Please could anyone suggest what might be going wrong?

What is going wrong?
I'd recommend getting the latest version from github
https://github.com/django-nonrel/django-nonrel
You'd wanna use git to download it rather than pip.
I am trying to build adblockplus from this link. When I issue the command:
python build.py build
I end up getting the following error message. I tried with and without sudo to no avail.

Am I missing a package? Any hint on what the problem could be will be much appreciated.
The stack trace makes it clear that the issue is caused by the following line:
(result, dummy) = subprocess.Popen(['hg', 'id', '-n'], stdout=subprocess.PIPE).communicate()
If you look at the subprocess package documentation, this line is trying to run the hg id -n command (get numerical Mercurial revision). Apparently, the Mercurial command line tool isn't present on your system (a possibility that this build script didn't consider) so it fails.
Disclaimer: I happen to be the one who wrote this script and I fixed this bug now. Mercurial isn't essential for the build, the revision number is pretty much only necessary to determine the output file name.
